Are Gray Wolves Endangered in the Northern Rocky Mountains? A Role for Social Science in Listing Determinations

Posted on November 29, 2021

Conservation scientists increasingly recognize the need to incorporate the social sciences into policy decisions. In practice, however, considerable challenges to integrating the social and natural sciences remain. In this article, we review the US Fish and Wildlife Service’s (FWS) 2009 … read more

Developing Metapopulation Connectivity Criteria from Genetic and Habitat Data to Recover the Endangered Mexican Wolf

Posted on July 6, 2020

Restoring connectivity between fragmented populations is an important tool for alleviating genetic threats to endangered species. Yet recovery plans typically lack quantitative criteria for ensuring such population connectivity. We demonstrate how models that integrate habitat, genetic, and demographic data can … read more

On Wolves and Deertinyurl.com/38pm7awcFirst to clarify, a wolf pack uses my property on a regular basis. I have been driven out of the woods by mosquitoes, black flies and ticks but never a wolf.I have heard wolves howl and bark. I have seen them, found their territorial markings and they have bedded down in my field. I do not carry a gun when walking my trails. I am only armed with knowledge. I am also a dog owner. I don’t turn her loose on a busy highway and I don’t let her chase wildlife.There is an inherent risk to hunting with dogs. Nearly all the dogs killed by wolves were in pursuit of game, mostly bear, released into known wolf pack territories. Even though DNR makes “caution areas” widely known, hunters continue to release dogs into those areas.The relationship between the wolf and deer is complex and the deer population is not primarily driven by the wolf population or wolf predation.Winter weather, habitat and overall fitness play a role in deer being successful in avoiding the wolf or the wolf will be successful in capturing its prey. An open field clear of snow will give the advantage to the deer who can outrun the wolf; whereas deer can get bogged down in deep snows giving the advantage to the wolf that, with its large, “snowshoe” paws, can walk on top.The publication (Factors Limiting Deer Abundance in the UP) explained that nearly 70% of wolf predations of adult does occurred in late winter and spring when body condition of deer was poorest. Nearly half of the adult does killed by wolves in the high snowfall zone were in such poor condition that they would have likely died even if not preyed upon. The report further states, “Predation from wolves is simply one portion of what impacts our deer herd in the Upper Peninsula, they are not solely responsible for the variation.”The relationship between wolves and deer are intricately linked each having a strong influence on the other’s survival. But, along with adequate prey, wolves also need human tolerance to thrive.photo: John E. Marriott Wildlife and Nature Photography ... See MoreSee Less
