Technical report integrating beaver and road ecology (June 2020)

Click to read about this integrated approach for providing both turtle passage and beaver exclusion from drainage culverts on a highway in eastern Ontario. This project spanned four years and trialled several wildlife exclusion fence installation methods, several beaver culvert exclusion methods, and turtle passage through an upsized Corrugated Steel Pipe. Find out more in this summary video presented at Beaver Con 2020.

This winter Eco-Kare will be completing the BeaverCorps Training with the Beaver Institute. We will be looking for field sites in the spring of 2021 to install our beaver exclusion and road ecological techniques!

New compilation for Transportation Research Board (September 2019)

Road Passages and Barriers for Small Terrestrial Wildlife by Kari E. Gunson and Dr Marcel Huijser. A compilation of materials about wildlife crossing structures and fencing for animals smaller than a coyote (including mammals, turtles, snakes and amphibians). Completed with funding from the National Cooperative Highway Research Programme.

Report 5 (Download a copy here)

Eco-Kare worked with MTO Head Office (Brenda Carruthers) to evaluate the use of a new Wildlife Habitat Awareness (WHA) sign policy, evaluation was positive, and the policy has been approved with recommendations for implementation on provincial highways.

  • Features four years of monitoring effectiveness of Wildlife Habitat Awareness Signs (WHA) on highways in Southern and Northeastern Ontario;
  • Includes traffic speed studies, road surveying and in-person motorist surveys
  • Before-After-Control-Impact study designs for traffic speed and road survey evaluation
