What is the primary function of wildlife corridors in urban environments?

Wildlife corridors serve a crucial function in urban environments by facilitating animal movement and reducing the likelihood of road collisions. These corridors create safe passages for wildlife to navigate through fragmented habitats that can result from urban development. As city areas expand, animals often face barriers such as roads and buildings that isolate populations and disrupt their natural migration and foraging behaviors.

By providing dedicated pathways, wildlife corridors allow animals to move between different habitats, ensuring they can access food, mates, and critical resources without having to navigate dangerous urban landscapes. This is particularly important in mitigating the impacts of roads, which can pose significant threats to animal safety and population viability by increasing the incidence of vehicle collisions. Furthermore, these corridors help maintain biodiversity by supporting genetic exchange between isolated populations, which is essential for healthy ecosystem functioning.

The other options do not align with the primary purpose of wildlife corridors. While urban wildlife tourism can be a byproduct of green spaces and nature access in urban areas, it is not the main function of wildlife corridors. Similarly, increasing urban development opportunities contradicts the objective of preserving wildlife movement; and separating different animal species is contrary to the goals of conservation and promoting biodiversity, as corridors aim to connect rather than divide.
