An evaluation of odor repellent effectiveness in prevention of wildlife-vehicle collisions.

摘要: Abstract Wildlife-vehicle collisions (WVC) amount to 11% of all registered traffic crashes in the Czech Republic causing, apart from numerous deaths and serious injuries animals, property damage car passengers. Odor repellents have potential lower overall number WVC allow animals cross roads at same time. We tested effectiveness odor repellent preparation prevention WVC. 18 places were selected on road network where concentrated basis crash data. Control sections segments also delimited order keep intensities constant. applied a Before-After-Control-Impact (BACI) study design control not only effect measures but expected natural variations wildlife populations over Data compared before after installations. Wildlife carcass gathering was carried out during spring autumn. used police database supplement data when no field works out. 201 killed mammals (roe deer wild boars) identified total 47 months. Bayesian approach as limited numbers available. A decrease between 26 – 43% can be treated sections. These are, however, up three-times than those claimed by producers preparations.
