New publication for Transportation Research Board

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.

New publication in Le Naturaliste Canadian

A comparison of turtle and snake passage at drainage culverts along two major highways in North America by Kari E. Gunson. (Download this paper as a pdf in English; or in French.)

Eco-Kare’s most recent monitoring reports are listed here. Including recently published work from the Valentine Wildlife Refuge, Nebraska with the worlds largest population of Blanding’s Turtles. See below for an overview of content and to download a copy.

Report 1 (Download a copy here)

Kari Gunson measures a Blanding’s turtle (Emydoidea blandingii) at Valentine National Wildlife Refuge, Nebraska, USA: Photo Credit: Marcel Huijser.

  • Field methods used pit-fall traps to capture turtles and mark. Then cameras in culverts to measure a connectivity index
  • First time ever formally documented use of eight Blanding’s Turtles using existing smaller drainage culverts along a major highway
  • Recommendations to extend and improve the existing chain-link fencing and to integrate additional turtle crossings

Report 2 (Download a copy here)

Black bear and cubs on overpass

  • A comprehensive compilation (139 pages) of mitigation effectiveness for large- to mid-sized animals
  • Mitigation comparison on 4 mitigated section on two highways: Highway 69 (mitigation implemented during road expansion from 2 to 4 lanes), and Highway 11 (mitigation implemented after road expansion)
  • Before-After-Control Impact designs using snow-tracking, carcass and wildlife-vehicle collision reporting from the Ontario Provincial Police to measure fencing effectiveness
  • Hotspot maps using Siriema software
  • Picture library with over 100 photos

Report 3 (Download a copy here)

Wildlife overpass drone picture by Timbercraft Consultation Inc.

  • Bulleted easy to read summarized methods, results and conclusions (59 pages) for five years of monitoring for large- and mid-sized animals on Highway 69
  • Evaluation of effectiveness of overpass, creek bridge pathways, box culverts, jump-outs and one-way gates
  • Best animal pictures captured on cameras, including Drone pictures of overpass also available in videos on website
  • Statistical analysis that evaluates observed and expected use of overpass and underpass by species

Report 4 (Download a copy here)

Snapping turtle entering tunnel

  • A comprehensive compilation of mitigation effectiveness for reptiles including the rare Blanding’s turtle
  • Best animal pictures captured on cameras from two years monitoring also available in videos on website
  • Camera set-up and evaluation for reptiles (cold-blooded animals)
  • Statistical analysis and discussions that build on work conducted by Baxter-Gilbert et al. 2015

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
  • Two types of sign evaluation: turtles and snakes

  • Development of province-wide, GIS-based, mitigation planning tools that prioritize where mitigation is most needed for Blanding’s Turtles and large animals on the MTO provincial road network as part of the MTO Wildlife Mitigation Program Analysis and Tools (WMPAT): Click here to see maps
  • Worked with a team of researchers for prioritizing mitigation measures on US highways in Idaho and South Dakota
  • Development of a draft municipal road ecology planning document for the City of Oakville (to be integrated into their Biodiversity Plan)
  • Watershed planning to prioritize mitigation for turtles in the Raisin Region Conservation Watershed, for Snapping Turtles and Jefferson Salamanders in Region Halton, and amphibians in Peel Municipality
