Wildlife corridors promote biodiversity, abate landscape fragmentation and – in areas of urban development – are often refuges for fauna. Yet, they appear at odds with their main goal of conserving wildlife's natural habitat, especially when applied to a real-world context, because they are typically located in areas prone to anthropogenic disturbances. The literature varies over how concurrent use affects wildlife. One such space where this occurs is urban parks where wildlife movement overlaps spatially with recreationists. Park visitors utilize formal trails and depart from them to create informal trails. Many negative consequences toward wild biota have been attributed to informal trails, which contribute to anthropogenic-induced fragmentation and, indirectly, disturbances within the matrix. The overlap of trails with wildlife corridors begs the questions: are wildlife using the shared corridors within the reservations or should landscape, resource and trail managers be directing their efforts elsewhere to facilitate wildlife movement? Also, to what degree, if any, will wildlife move through corridors shared with humans? To answer these questions, baseline and biodiversity data needed to be established first.
Employing round-the-clock, passive, remotely triggered camera pairs in two urban parks in greater Cleveland, Ohio, U.S.A., scenarios were tested along a continuum of wildlife-anthropogenic interfacing that occurs on trails. Formal and informal trails in Cleveland Metroparks were studied, in addition to an area with restored informal trails. Examining the majority of terrestrial, animal wildlife, likelihood of Verified Use was established for each species, guild, and as a whole. Verified Use was defined as any species being detected on both cameras in the pair within a +/- five minute window.
I found that non-consumptive, anthropogenic use of trails did not necessarily hinder terrestrial wildlife's movement as suggested in the literature. In situ, not (open full item for complete abstract)
