10 Tips To Help Protect Biodiversity from the Threats of Roads

  1. Limit driving (plan efficient routes, travel less at dawn and dusk when wildlife is on the move)
  2. Alternate modes of transportation (walk, bike, bus, train)
  3. Don’t litter (especially food items that attract wildlife onto the road)
  4. Comment on local road projects and inquire about road ecology strategies
  5. Participate in litter clean ups
  6. Pay attention and drive with extra caution through wildlife habitat (e.g. forest/wetland)
  7. Watch for wildlife and wildlife crossing signs
  8. Obey speed limits to increase reaction time to wildlife on the road
  9. Move wildlife off the road IF SAFE to do so (always move turtles in the same direction they are heading)
  10. Report wildlife/road interaction sightings

Road Ecology Mitigation Measures

A collaborative, well-planned approach will help to create transportation networks that decrease their impacts on wildlife.

There are many mitigation options available that include:

  • Road closures
  • Wildlife crossing signs
  • Reduced speed limits
  • Rumble strips
  • Speed bumps
  • Exclusion fencing & ecopassages
  • Route placement (i.e. avoid fragmenting wildlife habitat and bundling modes of transportation (e.g. road and rail) to maximize available habitat).

Road design elements:

  • Curbs (designs that enable small amphibians and reptiles to climb off the road)
  • Median permeability (to minimize trapping animals on roadways)
  • Road surface (choosing road surface materials that reduce noise and vibrations to minimize disturbing surrounding wildlife)
  • Line of sight (i.e. where feasible, reduce hills and curves to maximize visibility)
  • Lighting (design lighting to maximize motorist visibility, but reduce light pollution)
  • Vegetation (customize plant species, height, proximity to road and density to help reduce wildlife/vehicle collisions of target species).
