Transmission Wildlife Resources

Wildlife Resources
Present, Potentially Affected

The Fish and Wildlife Conservation Act, or “Non-game Act”, (16 U.S.C. 2901-2911 Stat. 1322) Public Law 96-366 provides,” financial and technical assistance to the States for the development, revision, and implementation of conservation plans and programs for non-game fish and wildlife.”


Federal agencies work with other federal, state, local and private agencies to achieve wildlife land management. Methods include, “scientific resources management, such as research, census, law enforcement, habitat acquisition, development, information, education, population manipulation, propagation, technical assistance to private landowners, live trapping, and transplantation.”


Wildlife Resources Impacts & Mitigation

Transmission line development influences wildlife behavior, habitat and mortality. Wildlife depend on habitats that foster biodiversity. Healthy ecosystems decrease single-species dependency, competition, and species depletion. Often times, wildlife have physical adaptations to blend with the surroundings, therefore, decreasing effects to natural features such as trees, shrubs, lakes, and rivers will allow barriers between human activity and predators. Several species migrate seasonally either to breed or satisfy dietary needs. Interrupting this process may lead to wildlife disease, mortality, and effect the food chain cycle. Typical mitigation measures include:


  • Gather migration pattern information on current and migrating wildlife near the proposed site.
  • Avoid activities between mid-April and mid-June to decrease impacts to migrating animals.


  • Use airtight containers for any trash that could attract wildlife. Remove trash and dispose off-site.
  • Post speed limits onsite and post wildlife crossing signs on all public roads to mitigate wildlife mortalities.
  • Construct light fixtures to point downward to discourage insects and bats.
  • Cover and fence holes or excavated areas overnight to discourage wildlife entry.
  • Develop a blasting plan to avoid sensitive wildlife habitats. Tailor blasting activities to avoid the wildlife breeding, migrating and high density times of year.

Onsite safety

  • Prohibit firearms onsite to mitigate unlawful hunting or harassment.
  • Instruct employees how to handle wildlife encounters.
  • Report wildlife problems and wildlife mortality to the appropriate wildlife agency.


  • Instruct all onsite drivers to stay on established roads to decrease wildlife impact in undisturbed areas.
  • Decrease long-term vegetation impacts by replacing any affected vegetation for wintering animals.
  • Reduce clearing all plants and trees to mitigate habitat loss.
  • Flag and map “no surface disturbance” areas.
  • Save tree snags, logs, and coarse woody debris throughout the site. Leave scattered piles to promote natural denning and loafing habitats.
