The Bay Area canyon mountain lion and people

She’s a cautious mountain lion. She wants nothing to do with people and does whatever is necessary to avoid them. She travels through the canyon on the wildlife and hiking trails during those times when she is less likely to encounter people. At the first hint of a human, she quietly disappears into the brush. She knows when there are people nearby because they’re loud, not just vocally but in other ways. They walk heavy, the ground creaks and rattles under their feet, grasses crunch. People aren’t subtle on the trails. Although pumas avoid humans, there are exceptions. Females can be belligerent when accompanied by cubs. Like all species, maternal instinct kicks in. Another exception is when a mountain lion feels cornered.

Many wild animals, including the canyon mountain lion, venture out between dusk to dawn to find food and other resources, times when human activity is minimal. The presence of people alters the dynamics between predators and prey, changes feeding behaviors^{1, 2} and the locations for hunting, foraging and sheltering. Although some species, including mountain lions and bobcats, are naturally nocturnal and/or crepuscular³, studies are showing that wild animals are shifting their activities from day to night to avoid humans⁴. People should be mindful and time-share the canyon and other natural spaces with the wild residents, only enjoying them during the day. The night belongs to wildlife. Don’t visit the canyon at night, instead walk on the street in the evenings and at night. The street runs parallel to the canyon and is less than four hundred yards away.

Our canyon mountain lion runs from a person

On the night of August 23^rd, in our bay area canyon, the mountain lion avoided an encounter with a walker who stumbled up the trail. Most likely, he had no idea that he was right behind the mountain lion, heading in the same direction. The time stamp on the first video shows the puma rushing up the trail at 8:39 PM. A few seconds later, at 8:40 PM, the walker is captured on film following closely behind her.

Mountain lions follow their prey

Mountain lions follow their food and their favorite meal is venison. The canyon is currently hosting a substantial number of deer. There is plenty of vegetation, water, and cover for them. Until recently, it’s been a relatively safe haven for the does and their fawns. Before the puma showed up in July, the only predators that raised concern were a pair of coyotes who are regulars in the canyon.

A mountain lion will kill and eat approximately one deer a week. Our canyon lion, like all pumas, doesn’t eat the whole thing in one sitting. She first drags the carcass somewhere nearby and then caches it; covering it with forest detritus to protect it from scavengers and reduce spoilage. Depending on the size of the prey and other environmental factors, it can take her between 2-5 days to consume it. Being a typical mountain lion, she’ll stay nearby, unless frightened away, until the carcass is eaten or spoiled. She isn’t the only one who benefits from her hunting prowess. When she’s away from the carcass, other animals have a chance to grab a quick bite—coyotes, raptors, skunks, and other wildlife benefit from the puma’s successful hunt.

On August 22^nd, our bay area canyon mountain lion stalked and ambushed a fawn, one of two who was birthed by a lame, resident doe. Although sad to see, the death of that one fawn is ecologically significant. That fawn died so that others can live and thrive. Her death was not in vain—it contributed to keeping the eco-system balanced and healthy. She fed the community.

The delicate balance of the ecosystem

The presence of the mountain lion in the bay area canyon serves as a powerful reminder of the delicate balance between wildlife and human activity. Our puma plays a crucial role in maintaining the health of the canyon ecosystem. By regulating the deer population, she helps prevent overgrazing, reduces disease transmission (including Lyme disease), and provides sustenance for other wildlife. Additionally, because she is an opportunistic hunter she hunts smaller prey including rats.

By being mindful of our impact on the environment and sharing these spaces responsibly with wildlife and bay area mountain lions, we can help maintain the health of the ecosystem and its wild residents. The canyon, with its rich ecosystem, offers a sanctuary for many species, and it is our duty to protect and preserve it. One small way we can help the ecosystem is to enjoy the canyon only during the day—don’t go there at night. The night belongs to the wild ones. Enjoy the canyon and other open spaces during the day and leave the night to its rightful inhabitants.

Future conservationists learning about the ecosystem

Simple activities that make a difference

Ecocentric activities can take a little or a lot of work. Some, such as not disturbing wildlife, not moving rocks (they may be sheltering someone) and staying on trails are passive activities. Others, including picking up trash (even if it isn’t yours), leashing dogs, removing their excrement and planting gardens to attract pollinators take more effort.

Pick a Flower and Trouble a Star

Everyone must be mindful of the effects that individual and collective actions have on the environment. The consequences of our actions ripple through the ecosystem. Even the seemingly innocent act of turning over a stone in a river can have devastating consequences and hasten the extinction of an endangered species¹

Larger projects carried out in open spaces including clearing trails and installing barbed wire fences and barriers across wildlife paths and corridors can fragment habitats, separate animal families and block food sources.

A new fence blocks a wildlife pathway.

A shoutout to the children

The 88-acre canyon that I love and write about, hosts a diversity of wildlife. Although a small habitat, it’s an important one. This wild space is part of a network of other natural areas, separated from each other by roads and buildings. The little canyon is also a popular hiking spot for the locals. It’s a perfect place to see how people’s activities impact the fragile environment.

There’s a wonderful eco-minded pre-school at the head of one of the trails that leads into the canyon. A few years ago, the young students started calling themselves The Jell-O Club.  The name wasn’t randomly picked. Like many preschoolers, the children were given mid-morning/mid-day snacks. After they and their eco-conscious parents noticed the plastic wrappers from their refreshments littering the canyon and floating down the creek, they asked the school’s director if they could have snacks that were in biodegradable packaging. These eco-minded youngsters didn’t stop there. They cleaned up the canyon trails, using pickers to grab up plastic, paper, metal and glass. To this day these little ones are still vigilante trail custodians. They are more than trail custodians; they are young conservationists in training, and they help keep the wildlife, dogs and hikers safe from the hazards of garbage and glass. The earth needs young vigilante conservationists like the Jell-O Club. They are making a difference.

Destruction of a shelter close to home

Until a few months ago, wildlife kept dry by crossing the canyon creek on a natural bridge made from branches intertwined between rocks, roots and the trunk of a large bay tree. The tangle of branches and leaves also provided shelter, cover and food for many species of wild animals. Generations of bobcats found the trunk and vegetation a safe spot to shelter and raise kittens. Although this was one of several shelters that the bobcat families used, they returned to it on a regular basis. Generations of kittens played, grew and learned essential survival skills on top of the branches and on the banks adjacent to the shelter.

Bobcats weren’t the only animals who hung out there. When the bobs weren’t around, possums would forage amongst the leaves and use the fallen branches and rocks as pathways to connect to the other side of the creek. Every night, dusky-footed woodrats, who are a species of special concern, ran over the tops of the large trunk that framed the creek. It worked well as a bridge, connecting to the bay trees where the woodrats built their large multi-generational homes.

For many years, this pile of rocks and branches played an important part in the lives of the wild residents. It supported many species for countless generations until one day a man with a shovel purposely destroyed it. It only took him one hour to eliminate it.

There were no reasons to demolish it. No human-made structures were nearby that could be impacted by the rising creek waters. Nature had successfully managed the creek for hundreds of years without this man’s help.

In addition to negatively impacting the animals, he destroyed part of a sensitive habitat that is home to species of special concern. Years ago, the county mandated that there can never be any building or modifications made in the canyon because it’s an environmentally sensitive riparian habitat. It is supposed to remain untouched.

Destruction of a wildlife crossing point and shelter

It was difficult to watch the videos of wildlife discovering that their familiar crossing point and shelter was gone.

Rat poisons

For ten years, an organization near one of the trail heads hired an exterminator to bait traps with 2^nd generation rodenticides. These deadly rat poisons remain in the tissues of the rats and travel up the food web. After eating the poison, the sick rodents don’t immediately die. The rats wandered into the canyon and neighboring yards and became easy targets for predators, including raptors, bobcats, pumas, coyotes as well as household dogs and cats.²

Bobcats help maintain a healthy ecosystem.

5 years ago, Slim, a beautiful mountain lion died after she ate a rodent that had eaten the bait. She had been frequently filmed late at night walking up the canyon trails, often hesitating at the junction where two two trails intersected.  Slim was one of many unintended victims of 2^nd generation rodenticide.

One person made a difference

Because of the perseverance of one man, the organization recently stopped using the poison. He successfully convinced the organizations board of directors to stop its use and dispose of the bait traps. He presented facts and suggested alternatives to 2^nd generation rodenticide for reducing the rat population.³ One person took action and made a difference.

You can make a difference

Although individually we may not be able to stop global warming, we can take actions that halt further destruction of the environment. We need to be mindful, think about the potential consequences of our actions and be aware of the ripple effect that our activities have on the ecosystem. We all need to do our parts to preserve and heal our fragile ecosystem.

1. Hellbender, an endangered species is in danger of disappearing forever. Because it makes it home under rocks in rivers, turning over, moving rocks displaces them “Once a nest rock is moved, hellbenders won’t ever use that rock again.” Stroup said. “There’s not a whole lot of clean, pristine habitat left for hellbenders. A lot of time we were damming rivers and creating lakes, we lost a lot of that riverine habitat for aquatic species.”
2. These rat poisons kill indiscriminately.  A study commissioned by California Department of Fish and Wildlife found 2^nd generation rat poison in 85% of the mountain lions, bobcats and fishers who were tested in California  In 2020, Governor Newson signed the bill which makes it illegal to use 2^nd generation rodenticides in California. Although it’s illegal, some people and businesses, including the canyon neighbor, hire exterminators, who place the lethal poison in bait boxes.
3. Rats are a problem, but there are better, safer ways of managing and reducing the population. You can make a difference and let natures’ exterminators do their jobs. Rats are regular parts of the predator’s diet. Additionally, remove food items, pick up dog and cat food and secure garbage cans and clear away brush will also help keep rats away from homes and businesses.

Among the notable wildlife recorded this summer, we are privileged to watch as bobcat kittens, a mountain lion cub and a spotted fawn grow and mature.

New bobcat family in the canyon.

Puma family saga

It is not new news that mountain lions are regulars in the canyon. They have lived in the area long before the first peoples came to California. My cameras have watched the wildlife in this canyon for only five years—a brief minute when compared to the length of time pumas have lived here.  Until this year, they have documented only solitary lions, never family groups or pairings. This year it is different. For the first time since the cams have peeked into the lives of the inhabitants, the canyon is fortunate to host a small puma family composed of a female along with her one cub. The pair has been captured on film almost every month since February. The first glimpse I saw of the little family was when the cub was around three months old.

Youngsters stick with their mums until they are between 18-24 months old. Then they disperse, searching for their own territories. Puma moms have difficult jobs. It is not an easy task to teach their young ones’ important survival skills. Living solitary lives, they must protect, hunt and raise the cubs without help. Unlike our local coyotes, mountain lions do not live peacefully with each other; they don’t live in packs and they don’t hunt cooperatively. Nor do adults willingly share their meals with conspecifics, but there are exceptions.

The puma mom is doing a good job. As her cub matures, she gives him more independence. One indication of this is her increasing the distance between them. But she is always nearby, ready to intervene, just in case there is danger.

The most recent appearance of the little family was in June, filmed at the rim of the canyon.

Bobcat soap opera

At least two litters of bobcats were born this year, probably from two different females. Usually, bobcats only have one litter a year. The kittens stay with their mums until they’re between eight to twelve months old and then disperse². Early this year three adorable bob kittens were recorded almost every day, playing with each other and annoying their mother. Although one of the babies had only one eye, he seemed to manage as well as his siblings.

Early this summer a new bob family was recorded in the canyon. The mom seems young; she may have been born about 18 months ago and possibly is the daughter of the female who, for at least four years, has claimed parts of the canyon as her core territory. Based on her behavior with the kittens, I’m guessing that this litter is a first for this girl. She doesn’t seem quite as vigilant as the older, experienced bobcat mum. Although she keeps track of the youngsters, they are a distance from her. Also, she only has two kittens. Young, first time mothers usually have fewer kittens then older females.³

The first time the babies were caught on film they were young, barely two months old. Mom may have been moving her little family to a new den. Kittens are frequently relocated, more when they are neonates, sometimes as often as every day to every few days. As they age they are moved less often. Predators also determine when it is time for a change of address⁴ because the little ones are vulnerable to predation by coyotes, raptors, puma and even male bobcats. The smell of the dens and the sounds of the kittens attract them.

The first time the babies were filmed, they may have been almost weaned, new graduates from the milk bar and barely getting accustomed to a meat diet. Around this time, they also start to learn to hunt. Bobcat moms have their work cut out for them: there are many mandatory survival skills these babies must learn in order to make it in a dangerous and competitive environment.

Mom is doing something right. Both kittens have survived another month—a hard task for a single mom. The little ones have grown and appear to be thriving. I love watching their immediate responses when their mom calls them. We definitely will keep a vigilant eye on those youngsters.

The camera at the fork in the trail is positioned at a popular spot for bobcats. Bobcats, like most felids live mostly solitary lives, they usually don’t socialize with other conspecifics unless they are juveniles ready to disperse, adults looking for mates or a queen raising kittens.

Coyote reality show

Coyote 09M was the canyon star for a few years. He was a joy to watch as he played and interacted with his mate and gamboled on the trail. 09M had a distinctive personality that showed through in the hundreds of videos of him.  The cameras lost track of him two years ago. Since he disappeared several coyotes have been filmed. None stayed for the length of time 09M did. While that boy lived in the canyon, he took a mate and produced at least two litters of adorable pups.

A bonded pair of young coyotes began hanging out in the canyon a few months ago. Tragically, the male was badly injured in July and lost a foot.  We can only guess the initial event—he could have gotten his foot caught in a trap or he may have been bitten by a rattlesnake. It is one of many wildlife mysteries that probably will never be solved. It is difficult for coyotes to successfully hunt when injured to that degree—sadly the survival rate is low. Now, only the female has been spotted.

Deer tales

There is a smorgasbord of vegetation for the deer to dine on in the canyon—a major attractant for a doe and her fawn. The two have found plenty to munch on, especially next to the creek, directly in front of one of my cameras.

In contrast to the bobs and lions, deer are highly social, and hang together in herds. There is safety in numbers—herds give deer some protection against coyotes and mountain lions. The characteristic of individual herds vary and are dependent on the ages, gender, familial ties as well as the season. Bucks group themselves in “bachelor groups” in the spring, but then become rivals when competing for the attentions of the does. Bachelor groups usually have three to six individuals in them. Ours has five members.

Wildlife dramas continue

The wildlife soap opera continues and because of technology, we are fortunate to be able to catch fleeting, 20 second glimpses into the fascinating lives of the canyon animals. It’s wonderful to watch as they live out their lives, hunting, playing and interacting with each other.  The cameras also play an important part in monitoring the behavior changes of our wild inhabitants caused by the pressures of urbanization and the fragmenting of their habitats.

Mountain lion latrines: photo courtesy of Felidae Conservation Fund/Bay Area Puma Project

FelidaeFund/Bay Area Puma Project is using non-invasive methods to collect mountain lion scat for research. The excrement is used for monitoring the health and genetics of the local puma populations. Although people do stumble across puma scat and occasionally latrines, we aren’t very efficient or successful at finding them. And, sometimes coyote or another meso-predator’s scat is mistaken as having been left behind by a puma. Because trained scent dogs are more successful and much faster at finding scat then humans are, FelidaeFund recruited Finn, a smart working dog, along with her well-trained handler, Michelle for the job. Watching the team work was impressive.

Scent dog team searching for mountain lion scat

When Finn first detected the lion’s scent next to my wildlife camera at the bottom of the canyon she sprinted straight up the steep 85 degree incline, through sticky brush and tall grass until she found her prize—puma poop. The two human members of the team followed close behind her. Not wanting to slow everyone down, I waited below, my eyes fixated on my phone; waiting impatiently for texts about what the dog had found.  Finn’s sensitive nose led the team to a welcomed find—mountain lion latrines.

Mountain lion latrines

Mountain lion latrines are often found near puma kills, sometimes adjacent to a trail and/or under brush. Although, they can be within 15 feet or so from the carcass, they can also be located further away¹. Latrines can contain between 1-5 scats, but it varies widely; sometimes lions will defecate in one place several times or they’ll use it only once and then move on to another spot. According to the Mountain Lion Foundation the latrines vary in size and in mound height. After defecating in the latrines, lions will usually cover the excrement with forest detritus—this is one of the few circumstances when pumas cover². Possibly, covering the excrement near kills minimizes the possibility of unwelcomed predators, including other pumas, coyotes and bobcats from detecting the smell, being drawn to the fresh carcasses and helping themselves to free meals.³

The locations of mountain lion latrines are not arbitrary. Pumas don’t sit down to a meal and eat the whole thing in one sitting; they consume their prey in multiple feedings. Because a single deer carcass can feed a puma for a few days to a week, it’s practical for lions to make latrines close to the carcass. Covering them reduces the smell factor.⁴

A mountain lion’s favorite meal is venison.

Genetic checks

The scat that Finn triumphantly tracked down contains genetic material as well as other valuable components that provide insights about the health of the individual who produced it. DNA analysis of the canyon scat coupled with a larger sample base collected from other Bay Area locations will reveal information about stress levels of the local lions and the amount of inbreeding that is occurring because of fragmented, shrinking habitats and blocked wildlife corridors. Collectively, the information will help establish the necessity of building wildlife crossings over and under the highways to encourage genetic diversity within the wildlife populations.

Health check ups

The scat Finn tracked down also provides details about the canyon mountain lions health and the general health of the ecosystem. It reveals the individuals’ menus, if they’re mostly consuming deer or relying on other prey animals for nourishment. Analysis will also identify the types of parasites and pathogens that are harbored in the puma’s systems as well as the presence of deadly second generation rodenticides. Thanks to Finn, collecting puma scat in the canyon was easy.

Dog with a job

Finn is a working dog. She has a highly tuned sense of smell and is blessed with millions more olfactory receptors then we sensory deprived humans possess. Having roughly 300 million olfactory receptors, her scenting capability is around 40 times more acute than ours. Because of her talented nose, she is trained to detect specific scents, including scat from a variety of animal species and even scents from a wide range of invasive plants. Finn and her person work for Working Dogs for Conservation and are excellent at their jobs.

Finn’s nose led her to the mountain lion latrines

Using force free methods, a diverse species of animals, including dogs, horses, pigs and cats can be trained to be successful scent animals⁵. The training process is relatively straight forward and includes drilling holes in sturdy, identical containers. Samples of objects that carry the scent the animal in training is being taught to recognize are put in a few of the containers, while the remaining are filled with other unrelated scents. When the animal trainee stops and sniffs at the container with the right scent, she’s reinforced. Clicker training is a fun, force free method commonly used to train animals.

Finn is very good at her job. After her nose led her to the puma poop, she sat down and excitedly wagged her tail. Of course, she was immediately reinforced with a treat for each triumphant success.

Who would think that puma poop plays such an important role in finding out about the health of the local puma population as well as other animals in the eco-system? The scat that Finn tracked down will provide wildlife researchers and conservationists with important genetic and health insights about the effects of urbanization.  Analysis of the scat from the canyon as well as from other locations in the area will hopefully contribute to projects that unblock wildlife corridors and create wildlife crossings under and over highways.

The trail camera was strategically placed

The stolen camera was recently placed strategically for research. We are collecting data about the mountain lions and bobcats and I am writing about their behaviors. My articles are based on the videos of wildlife that are memorialized by the cameras, including the one stolen from us.

A mountain lion mum and her growing cub periodically traverse the canyon. They are very adept at never being seen by people who use the trails—but the cameras see them. Recently Bay Area Puma Project/Felidaefund, as part of a broader DNA study, brought a scent dog into the canyon for the sole purpose of locating and collecting mountain lion scat for genetic and health research. The spot I placed the stolen trail camera is one of the areas the scent dog identified as a puma latrine. My next article, which I was working on before the camera was stolen, will focus on puma scat and the working scent dog.

Our trail cameras document wildlife

This canyon cannot be developed for any reason—it must be protected and remain wild. It is part of a network of other shrinking open spaces that wildlife relies on in order to access resources for survival and persistence. The canyon is also fortunate to shelter some special species of concern. These animals and their canyon habitat are protected: the county will not allow development of any sort to occur there. Our cameras are positioned to document the diverse animal species in the canyon as they live their lives and navigate between the fragmented open spaces.

Before the trail camera was stolen, it often filmed the dusky-footed wood rat–one of the species of special concern. This is one of their homes.

Community support

After years of filming, monitoring and writing about the canyon wildlife, we know that the majority of the residents support our work. Based on neighborly conversations through the years, we believe that most of you treasure the canyon and understand the importance of preserving it. Clearly, you love and respect the environment and understand the adverse impacts that urbanization has on wildlife. Unfortunately, at least one local person doesn’t feel the same way, if he did, our equipment would not have been stolen. I just don’t understand why someone felt entitled to steal our camera. The theft was not done on an impulse. The cam was secured to a tree with a locked, steel cable, a security box and a padlock.

To the neighbor who stole the camera: do the right thing, either return the trail camera, the memory card and the security box or pay for them. Place them at the base of the tree from where you cut the cable and stole them. Unfortunately, because of your theft, the valuable night footage cannot be replaced. Please support us, instead of hindering our research.

The post Why Steal a Wildlife Research Trail Camera? appeared first on Urban Edge Wildlife.

Fragments of the Wild

Although 88 Acres may seem like a large area to the people who live on the rim and walk the trails, it isn’t large enough to successfully supply enough food, territory and mates for many of the wild animals who are regularly filmed there. This small wildlife oasis is only a small part of a network of other wild spaces in this suburban-scape. These natural places are separated from each other by busy roads, highways, fences and structures. In addition to these splintered, wild areas there is a large open space managed by the San Francisco Public Utilities Commission. In order to obtain enough food and to find mates, the animals have to travel between these green pockets. It’s dangerous for them; many do not survive past their first year, becoming victims of vehicles.

Share the space, avoid humans

Because of the size of the canyon, animals, including bobcats, coyotes, deer and mountain lions share the habitat with each other as well as the people who have discovered this small slice of paradise. Over the past 4 years, my wildlife cameras have recorded 1,000s of vignettes of wild animals hunting, patrolling, raising their young and living their lives along the trails that crisscross through the little wildlife oasis. Amazingly, the animals are mostly successful at avoiding people who hike, walk, jog and exercise their dogs on and off leash.

Mountain lion family

It is never predictable. Weeks can go by and only a few animals are captured on film, but then there are other times when the memory cards are full of extraordinary wildlife. Recently, the little canyon has been in for a treat. Along with the regular wild residents, mountain lions are visiting. Although we¹ regularly film pumas, this is the first time in 4 years that we are privileged to glimpse a little mountain lion family—a mom with her cub.

Lions in the hood

As a rule, pumas don’t want anything to do with humans and will attempt to time their visits to avoid us. Unfortunately, because of the increasing pressures of urbanization, it’s becoming harder for them to avoid detection. Their wild environments are shrinking, fragmenting and disappearing. As their habitats are squeezed, animals have little choice but to venture into nearby neighborhoods, seeking food, water and territory. Deer feast on plants around homes and the predators, including mountain lions and coyote, follow them. Felidae/Bay Area Puma Project conducted a study in the San Francisco Bay Area to predict the habitats that mountain lions occupy in these highly fragmented urban and suburban landscapes. The study found that instead of pumas being partial to areas with a high density of prey (deer), they prefer forested habitats that have sufficient cover that supports their stalk and ambush hunting strategies.

Human residents are seeing wild animals with increasing frequency. Recently, a home security camera located near the canyon filmed a large male mountain lion killing a female lion early in the morning and then dragging her down the street.

Mountain lions are highly territorial; males especially do not tolerate other lions in their territory. If their habitats weren’t shrinking and becoming increasingly splintered, the two may have never encountered each other. It is possible that both lions followed the deer into the neighborhood where the fatal confrontation occurred.

This may be a video of the male lion, crossing the busy road that borders the canyon a week after the deadly battle.

Usually our local mountain lions visit the canyon late at night, when people aren’t around. A study was conducted about five years ago that showed that even the sound of human voices was enough to startle them away from their meals. Confrontations with humans are rare. According to California Fish and Wildlife, there have been 19 attacks since 1984. Of those 19, three were fatal. The last fatality in the Bay Area occurred in 1909 in Morgan Hill and that mountain lion had rabies.

Although encounters between mountain lions and people are rare, it’s important to be cautious. Children should always be accompanied by adults and it’s safer to not hike alone. If you do happen to see a puma or a coyote, don’t run. Instead morph into a large, fearsome human—wave your arms, do jumping jacks and yell. Minimize your chances of crossing paths with predators by enjoying the wild areas only during the day. Pumas are generally the most active between dusk and dawn. Thousand of videos from trail cameras show wildlife activity occurring predominantly at night and in the early morning, before first light.

We are fortunate to have natural habitats adjacent to our communities as well as small wild pockets within some of our towns. Unfortunately, because of the increase in urbanization and the growing population, these habitats are disappearing, becoming increasingly fragmented and reduced in size. By themselves, they are not large enough to support and sustain healthy ecosystems—but, together they form a network. Wildlife has no choice but to travel across dangerous roads and sometimes into the neighborhoods in order to access these wild areas for food and mates. Although they want to avoid people, expect to occasionally spot wild animals on the roads, in your yards and on security cameras².

1. Years ago I started monitoring cameras in this canyon solely for the Bay Area Puma Project (Felidae Conservation Fund)–one of our scientists identified it as good location for research. After a few years, BAPP turned it over to me and although it’s still part of our research, it is the primary focus of my articles.

The post A Wildlife Oasis in Suburbia appeared first on Urban Edge Wildlife.

“As humans have developed and destroyed habitats worldwide, it is critically important to keeping remaining isolated patches of habitat connected to each other with corridors of similar habitat, to allow animals (and thus their genes) to move between them.  Conservation biologists refer to this as ‘connectivity'”. Laurence Frank PhD–Living with Lions, Kenya

Wild animals go where there is food and water. It doesn’t matter what service they provide in the ecosystem—predator and prey must eat to survive. Deer are drawn to areas where there is plenty of vegetation—generations follow the same wildlife paths, going back and forth between sites that are proven to be rich in vegetation. They browse and graze on leaves and grasses in one area, then move to others, eventually circling back to the original spot. Predators, including mountain lions and coyote follow them. It is vital that these wildlife routes are kept open and are not made impassible. Additionally, keeping these wildlife corridors accessible discourages inbreeding and may help to deter predators from venturing into urban and suburban areas.

This wildlife path has been followed for years by many generations of deer

Wildlife corridors

Barbed wire fences, barriers and tall fences in our neighborhoods often obstruct the natural movement of wildlife. This is becoming more problematic as expanding urbanization divide and limit animals from accessing wild areas. The neighborhood canyon is no exception. Because the 88-acre canyon is too small to fully support a diverse and healthy group of animals, wildlife cross the busy street that borders one side of the canyon to access the open space. They graze in the meadow, browse on the vegetation, hunt prey and drink the water from the creek in the pristine habitat that is managed by the San Francisco Public Utilities Commission (Hetch Hetchy Regional Water System). The canyon side of the corridor is vital for wildlife as well—it is also a riparian zone and provides food, water and shelter for the animals. One of my cameras is aimed at the crossover spot at the fence the animals go through when crossing between the two wild areas. For many years it’s faithfully recorded a variety of species crossing back and forth.

For years and countless generations, animals have consistently passed through the fence at this spot. Youngsters, watching and following their parents, learned that this is the best place to make the crossing. They wait, hesitating at the fence, blending in with the shadows from the trees until the road is quiet and free of traffic and then dash over to the safety of the canyon.  Families of deer as well as coyotes, bobcats and mountain lions have worn paths under the horizontal barbed wires to go back and forth between the two wild areas. That spot at the fence is rich with the familial scents of thousands of animals over many years passing under and through the wires. Until recently, it worked well.

Everything changed a few weeks ago.

The SFPUC blocked the wildlife corridor

The SFPUC, recently weaved strong twisted wire strands between the horizontal wires in the fence, making it impossible for the deer to squeeze through. This wildlife artery, used by many wild species for crossing back and forth between the canyon and the open space is now impassible and dangerous for many animals.

SFPUC Added vertical wire to the fence, blocking the wildlife corridor

The SFPUC most likely made the poor decision to add the vertical wires because they don’t want people trespassing into the open space. Based on years of consistently filming the spot, their trespassing concerns are unfounded. In the 3.5 years that the camera has filmed the fence, there have only been four occasions when people have squeezed through the wires into the open space. Twice utility workers picked their way through the barbed wire, another time a house painter climbed through the wires to urinate. In 2019 a couple of trespassers did maneuver their way through the fence, probably to take pictures. While the SFPUC concerns are understandable, it appears that they are not considering the environmental implications of blocking a well-travelled wildlife corridor. It also seems that they are not honoring their own policy “Water Enterprise Environmental Stewardship Policy” concerning native species habitats and enhancing ecosystem function.

I don’t know if the SFPUC is aware of the detrimental impact that adding vertical wires between the horizontal ones has on the wildlife. The wires are now locked in place, making it almost impossible for some of the animals to make those crucial trips between the canyon and the SFPUC land.

Does and fawns have it a little easier in some ways. Being smaller and not equipped with antlers, they can squeeze between the closely spaced wires, but at a painful price. They are frequently scraped and scarred by the sharp barbs.

In addition to the fence being almost impossible to pass through, bucks can get their antlers tangled in the barbed wire.  Tragically, bucks who are trapped by the fence, can become easy targets for coyotes or may die from starvation. They are particularly vulnerable right now because it’s fall, the rutting season, when the males are intent on finding mates. They wander more, increasing the possibility of getting entangled in the fence as well as being stuck on the road. Although a few does have managed to fit through the small openings between the wires, some of the members of their groups can’t—leaving them in dangerous and precarious situations on the road.

Finding safe passage

Of course, there are other places they can use to cross over between the canyon and the open space, but they aren’t as safe as the familiar spot in the fence: animals must walk a distance on the road and risk being hit by cars and trucks.

Mature buck can’t get through the fence–he’s stuck on the road

A possible solution to avoid blocking wildlife corridors

The SFPUC needs to stop blocking these important wildlife corridors with injurious fences and barriers. There is a solution that is low-cost as well as relatively easy to implement and it can include local communities. First, the SFPUC needs to identify these important wildlife corridors. These access points and corridors are easy to spot—they are the paths where the vegetation has been flattened and the soil hardened by many generations of hooves and paws. Wildlife cameras should be strategically placed to document the wildlife using the trails to cross between the wild areas. An added plus is that the cameras serve as a deterrent to trespassers. A lot of this work has already been done.  Local conservation/wildlife groups including the Felidae Conservation Fund has identified many wildlife corridors and has been monitoring them for many years. Additionally, the SFPUC can solicit volunteers from the community to monitor cameras and submit and analyze the data. Instead of blocking these spots, cameras can continue to monitor them. When appropriate, signs should be placed on roads, indicating to drivers where the wildlife crossings are located.

What is occurring to the wild animals in the neighborhood canyon is not a unique situation. Tragically, wildlife corridors are being blocked in suburban and urban edge communities throughout the west. Who knows, maybe the local community and the SFPUC can set an example that might eventually be widely adopted, benefiting wildlife and helping people successfully cohabitate in areas that are shared by wild animals.

*The term “wildlife corridors” may not be scientifically accurate. According to the following definition, the term refers to a strip of natural habitat connecting populations of wildlife otherwise separated by cultivated land, roads, etc.

The post The Devastating Impact of Blocking Wildlife Corridors appeared first on Urban Edge Wildlife.

It’s always a delight to review the memory cards. Sometimes all we see are people, dogs and deer, other days, we are treated to videos of bobcats, the occasional mountain lion, coyotes and dusky footed woodrats.

During the last 10 days, bobcat kittens, rabbits and deer were the trail cams urban wildlife stars. The largest predators that were recorded were adult bobcats. Mountain lions, coyotes and foxes did not venture in front of the cameras.

Bobcat kitten

A bobcat kitten was repeatedly filmed bopping up and down the trail for a couple of days. The little one was not accompanied by mum or siblings—perhaps he was separated from his family. I hope that this baby eventually reunited with his mum. He’s too young and vulnerable to be out alone.

The next day he’s filmed again, but this time heading in the opposite direction on the trail. There are five more videos of this sweet baby alone.

Something startled this youngster. He might be the same little solitary bobcat kitten from a few days ago, but the ruff around his face seems more prominent than the kitten’s. This little one is so frightened, he momentarily freezes in place, then hurries away, keeping as low to the ground as possible, trying not to be seen. No possible threats were recorded before or after.

More bobcats

This gorgeous bobcat is frequently filmed near the creek. Check out the stripes on the inside of his back legs.

Deer

Deer are frequent visitors, often whole families show up, looking for vegetation to munch on.

Possum

These prehistoric looking marsupials fill an important niche in the eco-system. They are cleanup crews, eating an assortment of stuff, dead and alive, including garbage, snails and mice. Thank them—they also eat ticks. Unfortunately, the cams haven’t filmed any possums with babies riding on their backs.

Rabbit

There is at least one rabbit who lives at the fork in the trail. It’s amazing he hasn’t caught the eye of the resident predators. Rabbits are part of the diets of bobcats, coyotes and raptors. Usually he’s filmed at night, seldom during the day. I am rooting for his continual survival.

Protect the urban wildlife

Thank you to those of you who appreciate wildlife and understand the importance of keeping your dogs on leashes, not allowing them to run through the fragile habitats. You set a good example.

The cameras give us small windows for viewing the fragile eco-system. They let us glimpse vignettes of canyon wildlife and how it’s impacted by humans as well as natural events.

The post A Ten day Glimpse of Urban Wildlife in the Canyon appeared first on Urban Edge Wildlife.

I created a spreadsheet, comparing videos from one camera during the same 13-day period in 2019 with those from the same dates in 2021. The data tells the story, and it is not good. It’s a tragedy to see the canyon trails, once a paradise vibrant with a diversity of wild animals, changed into a ghost town.

It probably isn’t a coincidence that at the same time there’s been a dramatic decrease in wild animals, there is a substantial increase of people, bicyclists and off-leash dogs that are racing through the sensitive habitats. People’s response to Covid19 is most likely behind this upsurge of activity. Comparing the footage from the 13 days in 2019 to the same period in 2021, it’s noted that in 2019 there was only one dog off leash, 18 walkers and one bicyclist filmed in the canyon. It’s a different story in 2021. During the same period, 62 dogs ran off-leash, 499 people walked the trail and there were 33 bicyclists. Most likely, the consequences from the increased usage, especially from the dogs who are allowed off-leash is significant enough that many animal residents have vacated. Unfortunately, Coyote 09M, his mate and pups have disappeared. The last puma was filmed in November and the last coyote was recorded in October 2020. And during the recent 13-day period only a couple of bobcats, one deer and a few skunks were filmed.

Comparison of number of people for same 13 day period in 2019 and 2021–18 people in 2019, compared to 499 in 2021. See spread sheet

Dogs and people

Many of the people who are accompanied by their four-footed companions are responsible dog people. Their dogs are leashed, and their excrement is bagged and removed. As a rule, they control their dogs and don’t let them run off the trail. Thank you for being mindful and doing your part in preserving the canyon and attempting to keep it safe for its wild inhabitants.

Unfortunately, most of the dogs are uncontrolled and race off the trails. All of these dogs have people trailing a distance behind them. During the 13-day study period in 2021, 62 dogs were filmed running off-leash while only 40 sported leashes. The off-leash dogs tore through the canyon, chasing deer and other wildlife and destroying dusky-footed woodrat homes.

Dogs running off leash comparison for same 13 day period in 2019 and 2021. 1 dog ran off leash in 2019, 62 in 2021. See spread sheet.

The dusky-footed woodrat has been designated a species of special concern. This special mammal lives in the canyon and is the main reason that the canyon is not allowed to be developed. Their homes can be 60 to 70 years old—and up to 6 feet high.

Dusky-footed woodrat home

Although it took years for dusky-footed woodrats to construct this home, it probably took less than a minute for it to be destroyed.

The wild animals have left

The increase of people and uncontrolled dogs may not be the whole story—there might be other factors that also contribute to the wild animals vacating the area. Although correlation does not imply causation, based on the comparison of videos from the same time periods for the two years as well as the reports from other nature preserves and parks, the upsurge of people, off-leash dogs and bicyclists are most likely the primary reason for the wild animals to now avoid the trail.

Wildlife sightings comparison for same 13 day period in 2019 and 2021. 46 Wild animals were filmed in 2019, 18 in 2021.See spread sheet

I realize that people want to see me post videos of the latest wildlife that uses the trails. I can’t post any for you simply because there aren’t any. Although the wild animals are conspicuously absent from around the canyon trail, every week we have hundreds of new videos that are populated only with people, dogs and bicyclists. The cams are purposely aimed at an angle to avoid recording faces—we do see legs, knees and shoes. And the cams regularly film people engaged in a range of mostly healthy activities including walking, running, exercising, singing and dancing. Sometimes unexplained events are also filmed such as these people carrying shovels. I hope they are using those shovels to fill in the areas on the trail that now have erosion issues and that they aren’t removing native plants. And why move the stick?

Thousands of videos filmed in the canyon since 2018 chronicle the usual seasonal cycles of the wildlife. Unfortunately, they’ve also recorded a huge decrease of wild animals on the trail. Based on the data comparisons from the two years, it appears that the consequence of increasing human activities, especially dogs running loose into the fragile habitats has driven the wild animals to abandon the areas around our canyon trails.

The post Where are the Wild Animals? appeared first on Urban Edge Wildlife.

After George died, the usual vibrant colors on the trail became dull

Life continues on

Despite the traumas and the natural and human made disasters that affect our world, life continues. In the midst of devastation, wildlife does its best to adapt, survive and regenerate. The life dramas in my favorite canyon still unfold and are continually recorded by my trail cameras. It’s all there, objectively imprinted on little memory cards which are copied and saved into the cloud. Thousands of 15-20 second videos document expected natural wildlife scenarios as well as the reactions of animals to unexpected events such as wildfires and the human responses to the pandemic.

Pandemic reset button

In addition to hoarding toilet paper during the initial pandemic months, people rarely ventured far from their back yards and front doors. Everyone was in lockdown. Streets became deserted, restaurants and businesses temporarily closed, downtowns were abandoned.  Urban centers transformed into ghost towns. Earth seemed to take note of the lack of human activity and momentarily reset herself. For the first time in years, the predominant sounds were bird calls and gentle breezes. The skies transformed into a rich blue and the mountains were no longer shrouded in brown smog. The air was so clear that the rock formations on the Farallon Islands were visible from the coast all day.  Many animals also responded to the absence of humans, changing their patterns and schedules, venturing into cities and neighborhoods at all hours.* This wasn’t just a local phenomenon, it was the same story throughout the world.

The memory cards were rich with images. They recorded more than the usual residents. Species that we’ve never seen before in the canyon were filmed. The animal’s schedules also changed—many, who before Covid-19 were typically recorded only late at night and early mornings, were filmed at all hours. Wild turkeys showed up and there was an increase in visits from coyote 09M, his mate and a couple of pups. Bobcats made a number of appearances regardless of the time of day. Although it proved to be a temporary re-wilding, it was refreshing to see.

People wanted out

The re-wilding was temporary. There’s only so long that humans can maintain their sanity restricted to their homes. At first, binge watching on Netflix, cleaning closets and socializing on Zoom help distract and eat up the hours, but after a couple months it took an emotional and psychological toll. Desperate to return to normalcy, people started driving again and they also searched for green places to walk. The local canyon trail was a little slice of wild almost in their back yards. Wanting to connect with nature, they over-crowded the trails.

Most everyone was respectful, keeping to the trails, enjoying nature and not tossing trash around. Many brought dogs with them—the majority of the dog people were responsible, keeping them leashed, on the trails and cleaning up after them. One conscientious walker unknowingly scooped up and bagged Coyote 09M’s poop—other predators may have appreciated the gesture. The cameras filmed it all.

The wildlife cams also caught walkers who let their dogs run off leash. Dogs were recorded trampling sensitive habitats and scaring the wildlife. The impact was immediately obvious—only a few wild animals were filmed.

Please be respectful and protective of the few wild areas that are left. Keep your dogs on leash—don’t let them run loose. It makes a big difference for the wildlife. Between our human developments and California’s wildfires, their habitats are dramatically shrinking.

The disasters keep coming

4 million acres have burned in California this year and it’s only the beginning of the fire season.  One of the fires, the CZU Lightning Complex Fire began the morning of August 16^th. It burned more than 86,500 acres in San Mateo and Santa Cruz Counties and was finally contained on September 22nd. Tragically, many animals perished while others fled for their lives—finding sanctuary in the remaining open spaces, near urban centers and in small patches of undeveloped wild spaces, including the little 90 acre canyon.

Because of the devastating fires that burned throughout the state, the quality of the air deteriorated. For weeks it hovered between hazardous and very unhealthy, sending people back into their homes where they could breathe. For a few days, the San Francisco Bay Area had the worse air quality in the world, some locations topping 500. During this time the cameras recorded an upsurge in animals and a decline in people. One lion was filmed frequently on all of my cameras. He hung around for about 3 weeks, having plenty to eat because the deer were abundant. Predators follow their food and venison is the mountain lion’s favorite meal. Note that this stunning lion is easy to distinguish because of the markings on his cheek.

Not surprisingly, very few coyotes were filmed while the lion favored the canyon. Although both are apex predators, lions are a threat to coyotes so they will avoid confrontations with the larger predator. The bobcats did stick around though; a number of them were filmed, including a little bobcat family. Originally there were 3 kittens in this family, unfortunately, only one survived.

During the last 8 months, the world turned upside down, and not in a good way. Every event, whether natural or manmade has repercussions on the environment and the eco-system—everything is impacted. Although, there are positive consequences, there is an over-abundance of negative ones.  It may seem out of our control, but there’s plenty we can do as individuals. Even though change needs to occur at government and corporate levels, we individuals can also make a difference. Actions as simple as picking up trash, keeping dogs on leashes in sensitive habitats, using renewable resources, recycling and planting trees are examples of a few activities that each of us can do that will help heal the earth.
