What are the benefits of wildlife crossings?
Benefits of reducing wildlife-vehicle collisions (WVCs)
Benefits to wildlife include protecting individual wildlife from death or injury, keeping populations intact, and allowing individuals free movement to access important habitats and resources, thus enhancing long-term survival and population viability.

Why do wildlife cross roads?
Because It Cuts Through Their Habitat! Roads present challenges to the protection of species, their natural habitats, and their unimpeded movement across landscapes, which is why Defenders of Wildlife is very active in reducing the impact that roads have on wildlife survival.
Do koalas use rope bridges?
Koalas may not have used the rope- bridges because: (1) trees connected by rope-bridges were unsuitable as consecutive feeding trees, (2) the rope-bridge connections to trees may have made it difficult for koalas to climb onto a bridge, (3) the rope-bridge was positioned too low (i.e. lower canopy level rather than mid …

What are the advantages of constructing an animal crossing over a highway instead of beneath it?
What are the advantages of constructing an animal crossing over a highway instead of beneath it? Not only are they keeping themselves off the road and reducing car-animal collisions right off the bat, but they also create paths that more reticent animals will follow, says Clevenger.
