Habitat and Highways

Nearly 4 million miles of roads and 200 million vehicles keep Americans moving. But our mobility comes with a price. Road kill has pushed some rare species --such as the panther and grizzly bear -- closer to extinction.

Defenders supports efforts to make roads less dangerous to wildlife. Also, we are working with state and local authorities to plan for the growth of communities to avoid or minimize the harm from future roads on wildlife and habitat.

Defenders' Habitat & Highways Campaign has two objectives:


  • Reduce the impact of roads and highways on wildlife and habitat. Existing roads should be modified where necessary to allow wildlife to cross, and minimize impact on the surrounding environment.
  • Reduce future impacts by incorporating wildlife conservation into transportation planning. Future road development should avoid wildlife habitats and environmentally sensitive places.

The $61 Million Question: How Can Transportation Enhancements Benefit Wildlife?

In the States

Each state has its own department of transportation which receives federal funding for roads and highways. Most of the planning for road building and improvements are made by the state DOT. Defenders encourages local planners and state DOTs to incorporate wildlife conservation into transportation planning to avoid further conflicts and habitat loss. Get informed and get involved to protect your state’s wildlife.
