Plenty of good habitat left in the Colorado Rockies, researchers conclude
By Summit Voice
FRISCO — New surveys by Colorado wildlife biologists suggest that pikas seem to be holding their own as temperatures rise in the Rocky Mountains. The study found that pikas remain well distributed in the Colorado high country.
“In their primary habitat, mainly at and above timberline where there is lots of talus, we find pikas almost everywhere we look,” said Amy Seglund, a species conservation biologist for Parks and Wildlife based in Montrose. Continue reading

Shifts in wildlife populations will affect Native American communities
FRISCO — Some big caribou herds in Alaska could lose more than 20 percent of their habitat as growing wildfires destroy critical foraging areas. Those changes will likely affect generations of Native American families whose existence is spiritually linked with the Arctic ungulates, researchers with the U.S. Geological Survey reported in a new study.
Rapidly warming Arctic temperatures are to blame — global warming increases the flammability of lichen-producing boreal forests, which are important winter habitat for caribou herds. Continue reading

Recent studies show that neonicotinoid pesticides can persist in the environment, so the decision to ban them from federal wildlife refuges is good news for bald eagles. bberwyn photo.
New directive ends some long-running legal squabbles
By Summit Voice
FRISCO — Federal wildlife and land managers say they’ll end the use of genetically engineered crops and ban systemic neonicotonoid pesticides in the next 18 months. In a July 17 memo chief of the National Wildlife Refuge System James Kurth wrote that it’s not essential for his agency to use the potentially harmful products to meet its wildlife management objectives. Read the FWS memorandum.
The U.S. Fish and Wildlife Service thus becomes the first federal agency to restrict the use of GE crops and neonicotinoids in farming in the U.S.
Public land and health watchdog groups have been challenging the agency over the use GE crops since 2005, including five lawsuits, two legal petitions and multitudes of administrative challenges and appeals, resulting in numerous court rulings against the agency. In one case, a judge ordered the agency to eradicate genetically engineered plants from wildlife refuges in the Southeast. Continue reading

State biologists to unveil plan aimed at bolstering deer herds
FRISCO — After studying the decline of Colorado mule deer populations for the past few years, state wildlife biologists are ready to unveil a new strategy aimed at stabilizing an bolstering deer numbers. Western Slope residents will be able to get an early look at the plan during the upcoming Aug. 9 mule deer summit in Glenwood Springs.
The event is free and open to the public. CPW and The Keystone Center invite public review and comments on the West Slope Mule Deer Strategy draft as it serves as a guide to future CPW efforts to increase mule deer populations in Western Colorado.

Data will help assess global warming impacts to Arctic wildlife

FRISCO — The latest generation of high-resolution satellite images may help scientists gain a better understanding of Arctic polar bear populations. Dwindling Arctic sea ice is seen a huge threat to the predators, but difficult field conditions make it challenging to get a clear picture of polar bear population dynamics.
Satellite images have also been used recently to track emperor penguins in Antarctica, and researchers are starting to rely on satellite images more and more. In a new study, U.S. Geological Survey biologists matched satellite surveys with ground-truthed counts. Continue reading

Wolves draw tourists to Denali National Park.
Death of breeding wolves affects pack size and persistence
FRISCO — Following a steep drop in the Denali National Park wolf population, biologists have documented how the death of breeding wolves affects pack size and persistence. The number of wolves in the 6million acre park in Alaska dropped from 143 in the fall of 2007 to just 55 wolves in the spring of 2013, raising concerns about impacts to tourism.
Many visitors come to Denali with the expectation of seeing wolves, but a recent state decision to allow wolf hunting in area previously deemed a buffer zone has had a big impact on wolf numbers. According to the latest research, the death of a breeding wolf sometimes results in a wolfpack disbanding. Continue reading

FRISCO — Colorado’s growing moose population is causing a safety issue in the popular Maroon Bells area, near Aspen, according to state wildlife officials, who say people are getting to close to the animals along the Crater Lake Trail. Forest Service rangers temporarily closed the trail, but said that risky behavior continues, despite numerous posted signs warning of the potential danger. Continue reading
