STUDY DESIGN TO ASSESS THE EFFECTS OF HIGHWAY MEDIAN BARRIERS ON WILDLIFE
Members of the public have expressed concerns about the implementation of continuous concrete median barriers on highways. The concern lies with the mortality of small animals and big game mammals during their attempts to cross freeways. The public has perceived an increased frequency of wildlife mortality since the construction of these medians. This report presents a simple and cost-effective study design to assess the effects of concrete median barriers on wildlife along 400-series highways in southern Ontario. The report discusses the wildlife species, issues, and hypotheses of particular interest, then summarizes current knowledge of roadway barrier effects on wildlife mortality, movements, and species diversity. Potential effects of concrete median barriers on wildlife are discussed and existing road-kill data presented. The proposed study design is based on the collection of road-kills for a minimun of five years from selected 2 km stretches of highway 401 with and without concrete median barriers. The proposed design focuses on 14 species of medium- and large-sized mammals, including valuable game and fur bearer species.
