The program examines highway impacts on species listed under the federal Endangered Species Act (ESA) and works with the Idaho Fish and Game, Fish and Wildlife Service (USFWS), Forest Service, Bureau of Land Management, and others for the purpose of preserving, protecting, and enhancing the state’s natural resources while operating, maintaining, and improving the state’s transportation system.

Wildlife, fish, and sensitive plants require consideration during project planning and development. Areas of concern include:

  • Interference to wildlife functions such as wintering, foraging, migration, breeding and/or rearing
  • Effects related to collisions between vehicles and animals
  • Loss of animal or plant populations
  • Noise disturbance or loss of habitat
