Whenever I hike Kent’s Ledge, I chuckle at the idea of the passage under the highway as a potential wildlife corridor (though no one proclaims it to be one).  But it makes me consider how necessary continuous land segments are to preserving wildlife habitat and biological diversity.  America’s highways not only promote our driving culture and contribute to climate change, but also fragment habitat.  This Times article discuss how roadkill is being used by some to measure the actual deaths of animals on the road and better understand the environmental impacts of roads.
