Construction Guidelines for Wildlife Fencing and Associated Escape and Lateral Access Control Measures

Started: June, 2013 Ended: March, 2015 Project ID #4W4542 Status: Completed


The purpose of this project was to document U.S. and Canadian practices regarding the implementation of wildlife fences and associated measures.


WTI teamed with ICF and two consultants to conduct a national study of the best fencing methods and related structures that control wildlife along the nation’s roads.  While wildlife fencing is one of the most commonly applied mitigation measures to reduce wildlife-vehicle collisions, there are currently no generally agreed upon guidelines with regard to the length of the road sections that should be fenced, where fences should start and end, potential fence-end treatments to prevent fence-end runs, the height and type of wildlife fencing given the target species, escape opportunities for wildlife that end up in the fenced road corridor, or how to address potential gaps in the fence associated with access roads. This project conducted a literature review to document practices regarding the implementation of wildlife fences and associated mitigation measures for three different species groups: 1. Large mammals (e.g. deer (Odocoileus spp.) size and larger), 2. Medium sized mammals (e.g. coyote (Canis latrans), and 3. Reptiles and amphibians. The emphasis lies with practices in the United States and Canada.
