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.

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.

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.

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.

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.

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.
