Posted on April 2, 2022

A free-ranging Gray Wolf (Canis lupus), habituated to human presence (the author) on Ellesmere Island, Canada, learned to anticipate experimental feeding by a human, became impatient, persistent, and bold and exhibited stalking behaviour toward the food source. Only after the … read more

Forest Carnivore Conservation and Management in the Interior Columbia Basin: Issues and Environmental Correlates

Posted on August 29, 2021

Forest carnivores in the Pacific Northwest include 11 medium to large-sized mammalian species of canids, felids, mustelids, and ursids. These carnivores have widely differing status in the region, with some harvested in regulated furbearer seasons, some taken for depredations, and … read more

Wolves make roadways safer, generating large economic returns to predator conservation

Posted on May 30, 2021

Recent studies uncover cascading ecological effects resulting from removing and reintroducing predators into a landscape, but little is known about effects on human lives and property. We quantify the effects of restoring wolf populations by evaluating their influence on deer–vehicle … read more

Immigration does not offset harvest mortality in groups of a cooperatively breeding carnivore

Posted on January 30, 2021

The effects of harvest on cooperatively breeding species are often more complex than simply subtracting the number of animals that died from the group count. Changes in demographic rates, particularly dispersal, could offset some effects of harvest mortality in groups … read more

Population responses of common ravens to reintroduced gray wolves

Posted on November 30, 2020

Top predators have cascading effects throughout the food web, but their impacts on scavenger abundance are largely unknown. Gray wolves (Canis lupus) provide carrion to a suite of scavenger species, including the common raven (Corvus corax). Ravens are wide‐ranging and … read more

Colorado wolfpack no longer has working collars, causing concern among officialsbit.ly/3NdRLfhColorado's closely watched North Park wolfpack no longer has a working radio collar among its members, causing growing concern among ranchers, some wolf experts and the state wildlife agency.Colorado Parks and Wildlife confirmed to the Coloradoan the remaining working collar among the three fitted on pack members failed May 13. That collar was attached to the breeding adult male of the pack, which last year helped produce the state's fist pups in 80 years."Collars were the only way CPW could keep track of the wolves, so without the collars they are blind,'' said Gittleson, whose 11,000-acre ranch he leases northeast of Walden has been home to four of the state's five confirmed wolf kills of cattle.Carter Niemeyer spent three decades studying, killing and trapping gray wolves for the federal government before retiring. He now works with ranchers on how to coexist with wolves and sits on the Colorado Parks and Wildlife's Gray Wolf.He believes this is an ideal time to trap wolves for two reasons. He said using leghold traps would serve as a "spank and release'' to scare wolves away from cattle while allowing the capture of a wolf to be fitted with a collar.Leghold traps were banned by voters in 1996.Ed Bangs, who oversaw the U.S. Fish and Wildlife Service's gray wolf recovery program in the Northern Rocky Mountains before retiring in 2011, said using helicopters to capture and collar wolves this time of year is not ideal. He said the heat of summer stresses the animals, and vegetation makes it difficult to find wolves.The need to radio collar is because people get nervous not knowing where the animals are,'' said Bangs, who in the latter part of his career voiced concerns about using radio collars on wolves.Colorado Parks and Wildlife, which is partnering with lead agency U.S. Fish and Wildlife Service in managing wolves, said it does not plan to capture and collar wolves at this time.Photo: Colorado Parks and Wildlife ...

State and livestock industry depredations on wolves must endtinyurl.com/2h285e69We’re glad that the state-sponsored depredations on wolves are at a seven-year low, but that number needs to be reduced to zero, and that requirement should be formalized by either regulation by the state Fish and Game Commission or by state statute, whichever one it takes.When the word “depredations” is invoked, it’s usually describing wolf depredations on cattle and sheep. It’s kind of a dirty word, especially in rural circles, and describing wolves as doing the depredating is a slick and crafty way to make ranchers look like the victims. But more often than not, it’s when the ranchers push their cattle out onto public wildlands – which are the wolves’ homes – that these conflicts occur. So, really, aren’t the ranchers creating the problem by moving tasty treats into wolf habitats, at times even unloading the cattle truck right next to known wolf den sites?Let’s talk instead about the depredations of the livestock industry, and state and federal agencies, on native wildlife. It’s not just state agencies gunning down wolves. It’s entire U.S. Department of Agriculture programs dedicated to killing or poisoning wild species for the benefit of farmers and ranchers. It’s about county extension agents poisoning native rodents that are a key role in native ecosystems or trapping beavers to disrupt healthy rivers and streams. It’s about individual ranchers carrying rifles in their pickup trucks to gun down anything large enough to notice. This is a result of a failure of these groups – and by extension, our broader society – to coexist and live harmoniously with the natural world, because they are too busy laboring to dominate or destroy it.Humanity needs to retool its approach to the natural world, to transform its relationship from consumers and parasites to one of responsible members of the natural community. The Washington state government has a responsibility to do its part. At Western Watersheds Project, we call on them to lead, by ending the depredations on wolves and other native wildlife. We can and must do better in our relationship to nature.photo: John E. Marriott Wildlife and Nature Photography ... See MoreSee Less
