Conservationists consider road kill such a threat to species survival that they have begun looking for solutions through an emerging discipline known as road ecology.......Roads present more than just the potential for dangerous interactions between vehicles and wildlife; they fragment habitat and restrict the movement of wildlife species............. Although, many wildlife management and transportation agencies have worked to mitigate vehicle-associated incidents with wildlife on our roadways, there is still much to learn about the ways in which wildlife interact with roads.......Joe Northrup and his colleagues at the University of Alberta, Edmonton and the University of Calgary documented the response of grizzlies to vehicular traffic noting that roads themselves are not so detrimental to wildlife, and grizzly bears in particular, but that the human use of roads is what needs to be examined............What they found was that bears avoided roads with high and medium traffic volumes and instead used low traffic volume roads and crossed these low volume roads with greater frequency............ They also found that bears utilized private agricultural land over multi-use public land............ The agricultural land was typically higher in road density, but lower in traffic volume.......In fact, traffic had a greater impact on bear behavior than road density........... .Typically management plans focus on limiting road density, but with increasing industrial development in bear habitat, this is becoming difficult.............. Incorporating measures aimed at reducing traffic, such as access management, into these plans will be an important step for bear conservation

Writing in his 1859 book On the Origin of Species, which laid down the foundations of evolution as a science, Darwin reported, "There are two varieties of the wolf inhabiting the Catskill Mountains, in the United States, one with a light greyhound-like form, which pursues deer, and the other more bulky, with shorter legs, which more frequently attacks the shepherd's flocks."..........The debate continues as to whether the Eastern Wolf is a distinct species(same as the Red Wolf now relegated to the barrier islands in North Carolina) or is a subspecies of the Gray Wolf(a wolf/coyote hybrid)..............Very smart scientists come out on both sides of this equation with the US Fish & Wildlife folks beginning to side with the "distinct species" classification,,,,,,,This could lead to gray wolves being delisted in the Eastern USA,,,,,,,,,,,, In my opinion, this would be a bad thing unless this same Agency gave Endangered Species Protection to the Eastern Wolf .............I say this because under the endangered species classification, the USFW folks have a mandate to restore the endangered animal to regions of its former habitat deemed still suitable to support their existance...........There have been peer reviewed studies done that state that suitable gray wolf habitat exists in New England and NY State to support several thousand gray wolves..................If the USFW delists the gray wolf in the East, there is no chance for wolves being restored to this geographic region unless this same Agency designates Eastern Wolves as endangered..............A complex and urgent issue this is and near and dear to my heart as it is one of the initial reasons why I began this blog two years ago--We will continue to monitor this issue closely and provide you with updates as to what-happens-next for Wolves east of the Mississippi
