Assessment Of The Efficacy Of The Hose-Bridge As A Road-Crossing Structure For Dekay's Brownsnake (Storeria Dekayi), Sarah Elizabeth Manka

Masters Theses

Various structures have been integrated into roadways to ensure the road does not impede wildlife movements between adjacent habitats. Where traffic volume is low, the costs of installing and maintaining such structures is typically prohibitive. I tested the efficacy of a hose-bridge deployed temporarily on a State Park road in Illinois that allowed the passage of cars over it and small wildlife species to cross through it. I predicted that, during the 4.5 -week period of peak migratory movement, road-based mortality of Dekay's Brownsnakes (Storeria dekayi) would be less at the site having the hose-bridge, when compared to ...
