Low-impact human recreation changes wildlife behavior

Published on January 19, 2023

Just like a dominant predator, humans can influence the behavior of wildlife even without the use of hunting rifles. A recent study in Glacier National Park observed how human presence on hiking trails affected the movement of 22 mammal species. The findings suggest that humans can create a ‘landscape of fear,’ causing animals to change their access and activity patterns. Some species completely avoided certain areas, while others used them less frequently. In order to avoid humans, some animals even became more active during nighttime hours. These results reveal the profound impact that low-impact human recreation can have on wildlife behavior.

This research supports the idea that our mere presence can alter ecosystems and disrupt the natural behavior of wildlife. It’s fascinating to think about how our actions as humans can shape the environment in ways similar to apex predators. By understanding these effects, we can work towards more sustainable practices that minimize negative impacts on wildlife.

Even without hunting rifles, humans appear to have a strong negative influence on the movement of wildlife. A study of Glacier National Park hiking trails during and after a COVID-19 closure adds evidence to the theory that humans can create a ‘landscape of fear’ like other apex predators, changing how species use an area simply with their presence. Researchers found that when human hikers were present, 16 out of 22 mammal species, including predators and prey alike, changed where and when they accessed areas. Some completely abandoned places they previously used, others used them less frequently, and some shifted to more nocturnal activities to avoid humans.
