Elk deemed mostly responsible for spreading disease to livestock
The most rapidly spreading strains of brucellosis, a disease with implications for livestock and wildlife management, appear to be centered around areas where humans feed elk to keep populations artificially high for hunters.
Those findings come from scientists with the U.S. Geological Survey and partners, who studied how the disease is transmitted back and forth between cattle, bison and elk in the greater Yellowstone area. Notably, the researchers found that a fifth, genetically distinct strain, originated, and was mainly found in bison of Yellowstone National Park. This strain appeared to be spreading less rapidly.

Trapping and hunting near parks cuts has big impact
Many Americans travel thousands of miles for a chance to spot wolves in the wild, but a new study shows that their chance of spotting the predators decreases dramatically when hunting and trapping is allowed. In 2013, Public Employees for Environmental Responsibility first raised the alarm that dwindling wolf numbers near Denali National Park are affecting wildlife watching.
The new research, published in the journal PLOS ONE, suggests visitors to national parks were just half as likely to see wolves in their natural habitat when wolf hunting was permitted just outside Denali National Park’s boundaries during a period from 1997- 2013. Other important factors linked to wolf viewing rates include, the proximity of wolf dens to the Park Road and the regional wolf population.
Colorado Parks and Wildlife is looking to add members to its Summit County Wildlife Transport Team, an all volunteer group of citizens devoted to helping the agency respond to wildlife emergencies.
Interested residents can get more information at a May 16 information session, 7 p.m. at the North Branch Library in Silverthorne. During the session, CPW will screen applicants and review requirements and expectations.
“Volunteers help us by responding and assisting with certain types of wildlife calls, usually small mammals and birds that are injured or causing a nuisance,” said District Wildlife Manager Elissa Knox of Summit County. “Our current team has several seasoned volunteers that are an invaluable asset. We encourage people to join them and help us educate the public and help wildlife.” Continue reading “Volunteers needed for Summit County wildlife rescue team”→
Wolf advocates hope for more releases of captive-bred wolves
The U.S. Fish and Wildlife Service this week agreed to prepare a recovery plan for Mexican gray wolves by 2017. The court settlement will compel the federal agency to finally meet its legal obligation to ensure that the wolves can establish a healthy, sustainable population. The settlement may speed up the slow-going conservation and recovery effort.
The settlement came in response to a lawsuit filed by a coalition of wolf-conservation groups, environmental organizations and a retired federal wolf biologist. Less than 100 Mexican gray wolves exist in the wild, making it one of the most endangered mammals in North America. The settlement follows a September 2015 ruling by a federal judge in Tucson that rejected the government’s effort to dismiss the case.
Three other men also face fines for related crimes
A Colorado man has been ordered to pay more than $14,000 in fines after pleading guilty to numerous poaching charges charges.
According to Colorado Parks and Wildlife, 59-year-old Melvin Weaver killed three bull elk on the Uncompahgre Plateau west of Montrose last fall, then called friends and told them to come to the location and to use their licenses to claim the animals as their own. In Colorado, hunters can only tag animals that they have shot themselves. Continue reading “Colorado poacher gets big fine after illegal elk killing”→
Even though I’m not a wildlife photographer, every now and then, a hapless animal cross in front of my lens. If I’m lucky, I manage to snap the shutter at the right moment to capture a halfway decent image. That always makes me happy, until I remember that humanity’s completely unsustainable approach to life is putting many other species at serious risk of extinction. Pesticides threaten many insects, especially pollinators that are so critical to ensuring a sustainable food supply. Reptiles like turtles are also threatened by impacts to water quality and wetlands, and many other species are being lost because of habitat fragmentation and, of course, climate change. If we can’t find ways to sustain the web of life that sustains us, we’re likely to become an endangered species ourselves. Some people would argue that we already are.

Reduced snow cover driven by global warming is squeezing snowshoe hares out of some parts of the species’ historic range, according to researchers with the University of Madison-Wisconsin. According to the study, the range of the hare in Wisconsin is creeping north by about five and a half miles per decade, closely tracking the diminishing snow cover the animal requires to be successful.
“The snowshoe hare is perfectly modeled for life on snow,” saud Jonathan Pauli, a UW-Madison professor of forest and wildlife ecology and one of the co-authors of the new study, published in Proceedings of the Royal Society B. “They’re adapted to glide on top of the snow and to blend in with the historical colors of the landscape.” Continue reading “Global warming shifts range of showshoe hares”→
