It is not paths that disturb forest birds, but the people on them – ScienceDaily


The first study to solve the impact of forestry paths of people's presence shows that birds, as well as bird species, are lower when routine routes are used regularly. This is also the case when paths have been used for many years, suggesting that forest birds are not used in this recreational activity. Published in Boundaries in Ecology and Evolution, the perception suggests that physical presence of paths has less impact on forest birds than how often these recreational routes are used by humans. In order to reduce the impact on these forest creatures, people should avoid roaming from designated routes.

"We show that people are severely affected by forest birds and this avoidance behavior does not disappear even after years of human use. This suggests that not all birds belong to people and that there is a continuing impact, "said Dr Yves Bötsch, leading author of this study, at the Swiss Ornithological Institute of Sempach, Switzerland and associated with the Institute of Evolutionary Biology and Environmental Studies, Zurich University, Switzerland . "This is important to show that pressure on natural habitats and nature conservation areas is becoming stronger and frequent access bans are ignored."

Many outdoor activities depend on infrastructure, with roads and paths most common. Previous research has shown that paths cause habitat loss and fragmentation, where more areas of habitat are split and smaller, separating wildlife populations. However, it has been difficult to say in particular whether there is a presence of paths or people who have the greatest impact on forest birds.

Bötsch explains, "Previous studies give the results of conflicts about the effects of paths on birds, with some studies showing negative effects while others do not. We believe that differences in human consumption density can cause. This inconsistency, which motivated us to solve the impact of paths of people's presence. "

The researchers visited four forests with a similar habitat, such as the types of trees, but that were different in the recreational levels. All the birds heard and seen in nearby areas and paths were recorded, as well as within the forest itself, and a lower number of birds were found to be recorded in the forests often used by humans. In addition, they notice that some species are affected more than others.

"High sensitivity, measured by flight start distance (the distance to which a bird is exposed to someone flying aviation) showed avoids stronger runners, even rarely in forests attending & Woodland, and Eurasian crisp, as well as colonies and tree trees, "said Bötsch.

It continues, "It is generally assumed that hiking in nature does not harm wildlife, but our study shows even in forests that have been used recreationally for decades, birds have not used people in enough to offset the negative impact of human harassment. "

Bötsch ends with some advice, which could help reduce the adverse effects on forest birds by people who use forestry relaxed.

"We believe that safe areas with prohibited access are necessary and important, and new routes should not be promoted into remote forest areas. Visitors should be encouraged to existing forest routes to control" stay on track "and refrain from wandering from designating paths."
