Part 2: Signs of Human Presence

The new program for the grade 4 students visiting our trails revolvings around Noticing Signs of Animal Presence. Throughout February and March we had so much fun scouring Scowen Park for clues, investigating and discussing who might have left each clue behind. We were lucky enough to come across tracks, scat, signs of browsing and even some bones, fur and bits of skin left over from a White-Tailed Deer. Each outing served as a reminder that if we pay close enough attention, we can see signs of animals going about their activities all around us, even in the dead of winter.

 

What happens when animals of the Homo sapiens variety go about their activities in the forest? What types of clues do they leave behind?

In this article we will dive into the “Signs of Human Presence”, considering some of the usual signs left behind by the humans passing through natural areas and some of the not-so-usual signs that have a greater impact than we might realize. This is the second in a series of articles meant to encourage deeper reflection on the principles underlying the guidelines common to so many trail networks (see Part 1 on Respecting the Trail from the March-April newsletter). With the number of people enjoying natural spaces increasing, it is more important than ever to view park guidelines as invitations to participate in reducing our collective impact and hence preserving the natural areas we cherish.

 

Part 2: Signs of Human Presence

 

For the Love of Parks

 

In 2021, Parks Canada and Ontario Parks joined forces in promoting the For the Love of Parks campaign – one meant to “inspire visitors to enjoy (…) amazing places responsibly, for the enjoyment of everyone.” (Parks Canada)

 

Why do we visit natural areas? Presumably it is because there is something about them that draws us in, that is special and that we love. Why, then, would we make choices that slowly degrade these areas over time?

 

Oftentimes human actions (unwitting or not) pose a real threat to the ecological integrity of the spaces we frequent. “Ecosystems have integrity when they have their native components intact.” (Parks Canada) Organisations managing natural areas have a responsibility to keep this in mind when it comes to providing access to said areas. The mandate to make these areas accessible should never take precedence over the mandate to protect them. It is therefore everyone’s responsibility to uphold the integrity of these spaces – for the sake of preserving ecosystems and for the sake of preserving our right to access them.

 

Undesirable Number 1: Good Old Trash

 

It is heartbreaking and frustrating when we stumble across trash in the middle of a natural area. When we see this somewhere that is special to us… it almost feels personal. In addition to it being offensive and unsightly to other park visitors, it is problematic for wildlife because it doesn’t belong.

 

Everything in an ecosystem serves a purpose and is able to participate in a relatively balanced energetic exchange with the other components. Whether it be to provide substrate, nutrients or shelter, the role is necessary and the impact is moderated by the other processes going on simultaneously.

 

Trash is foreign and not only unable to contribute positively to an ecosystem, but can create an important imbalance. Firstly, trash takes a long time to degrade and while doing so, leaches toxins (and zero nutrients) into the soil. Second, various types of waste have the potential to cause needless suffering and even mortality. From empty bags to plastic containers, curious wildlife picking up the scent of food can become trapped and suffocate or starve to death. Other items can easily be mistaken for food and can be ingested, causing choking or other digestive issues that can lead to death. Moreover, whether mistaken for food or not, anything with a sharp edge to it can cause injury to unsuspecting critters, leaving them vulnerable.

 

Various forms of trash have the potential to take a lot from an ecosystem without giving a single thing in return… but what about the things that can eventually break down? Are they as bad?

 

The Not-So-Usual Suspects

“But… it’s biodegradable!” I hear this often during our fall post-outing snack when I ask students to chuck their apple cores in a brown paper bag instead of throwing it into the tall grass.

So many of us (myself included) have been taught that biodegradable equals harmless. It wasn’t until well into adulthood that I was able to fully grasp the importance of such a seemingly harmless action. Once again, it comes down to preserving ecosystem integrity. By leaving behind food waste we are indirectly feeding animals which can:

  • Be unhealthy for animals. Animals’ systems are made to process the foods that are found naturally in their habitats. Not a granola bar, even if it’s organic.
  • Cause animals to get habituated to humans. Animals catch on very quickly and can come to associate humans with food, eventually becoming nuisances as they hang around and beg for food, maybe even becoming aggressive. It’s all fun and cute until raccoons get bold.
  • Influence population numbers of one species to the detriment of another. To illustrate by way of an example: one study found that supplemental food significantly impacted Red Squirrel numbers and studies on Bicknell’s Thrush have shown that their nesting success is significantly impacted by Red Squirrel abundance. “In years when red squirrel populations are high, the reproductive success of Bicknell’s Thrush declines.” (Hinterland Who’s Who) Feeding squirrels could kill birds. Who knew?

 

Leaving behind additional food sources for wildlife creates an imbalance that can inconvenience humans and wildlife alike. Moreover, these ‘compostable items’ degrade far less quickly than we might think (e.g. banana and orange peel can take up to two years to break down in nature). Animals are capable of fending for themselves, our food scraps leave unnecessary extra resources, which can ultimately compromise ecosystem integrity.

 

Lastly, on the list of “Not-So-Usual Suspects”, we have facial tissue and toilet paper. Tissues often fall into the category of “But… it’s biodegradable!”

 

But are they and does it matter?

 

For all the reasons mentioned above, it is not advised to toss tissue paper in the forest and it bears mentioning that contrary to popular belief… it will not dissolve into the soil anytime soon. Actually, if left to do its thing, a tissue left in nature can take anywhere between one and three years to decompose completely! Not to mention it contributes nothing of value to the ecosystem as it does so.

 

Pack In, Pack Out

It can be easy to fall into the way of thinking that one single action by one single person is “no big deal”. This is when we have to stop and remind ourselves that none of our actions are ever truly isolated. We are part of a vast (and growing) whole. The choices we make have an impact and the more people who decide to make a similar choice, the greater the impact positive or negative.

 

So what to do with anything that comes into the forest? Treat it all like trash. Treat it like a real threat to the ecosystem’s integrity and bring it back with you. Always have a bag handy in your hiking pack so you can contain the messier things. You can do the sorting (compost, recycling, garbage) when you get home, feeling pleased with yourself that you chose to invest in the future of that beautiful place you just visited. And if you want to be a major investor – feel free to pick up the slack and also commit to removing anything left behind by others (when it’s safe, of course).

 

We go to these natural spaces because we enjoy them and appreciate them as they are. By choosing to leave nothing behind, to bring it all back out with us, we are actively upholding an ecosystem’s integrity and this is as much a solemn pledge to the natural spaces as it is to ourselves.
