State decides on endangered species status for wolves even as feds proceed with national de-listing push

FRISCO — When wolves start to reclaim their historic territories in the wilds of California, they’ll be protected under state law. The California Fish and Game Commission voted last week to protect gray wolves under the state’s Endangered Species Act after being petitioned by the Center for Biological Diversity.
The decision came just a few days after biologists documented the presence of two wolf pups in the Oregon portion of the Rogue River-Siskiyou National Forest that straddles the California-Oregon border. The pups, which are likely to be part of a litter of four to six pups, are the offspring of the wolf known as OR-7, which has made California part of his range for the past four years.

Proposed critical habitat for lynx in the northern Rockies, as mapped by the USFWS.
Colorado once again left out of critical habitat zone
By Bob Berwyn
FRISCO — Working under a court order, federal biologists have finished a revision of a critical habitat designation for threatened lynx — but once again, Colorado was left out of the equation.
The latest critical habitat designation, subject to a 90-day comment period, would cover about 41,547 square miles within the boundaries of five critical habitat units in the states of Maine, Minnesota, Montana, Idaho, Washington and Wyoming.
Colorado wasn’t included because the agency doesn’t believe that the state’s population is essential to the long-term conservation of the species, said U.S. Fish and Wildlife Service biologist Jim Zelenak.
“We looked at the historical record and the biological history of lynx in Colorado and it’s just not clear that Colorado ever supported a persistent population over time … We recognize the potential for lynx in the southern Rockies … but our approach has been to look at those places with persistent populations over time. We want to feel fairly certain that an area has the physical attributes needed to support lynx,” Zelenak said. Continue reading

Decision will trigger new reviews of forest plans and projects in northern Rockies
By Summit Voice
FRISCO — The U.S. Forest Service has once again been called out for failing to live up to its legal obligations to protect endangered species, this time by a federal judge in Montana, who ruled last week that the agency violated the Endangered Species Act when it failed to consult with the U.S. Fish and Wildlife Service on a regional forest plan amendment.
Dana L. Christensen, chief judge for the U.S. District Court for the State of Montana, ordered the Forest Service to re-initiate consultation, but did not block any specific projects on the affected forests, saying that plaintiffs couldn’t show any “irreparable harm.” Continue reading

New protected areas between Banff and Glacier national parks could help maintain wildlife populations
By Summit Voice
FRISCO — Species vulnerable to climate change impacts in the Canadian Rockies will need room to roam, according to a new report from the Wildlife Conservation Society Canada.
The report outlines a safe haven strategy designed around an assessment of six iconic species: Bull trout, westslope cutthroat trout, grizzly bears, wolverines, mountain goats and bighorn sheep — five of which were ranked as highly vulnerable to projected changes.
The area in question is located between Glacier National Park in Montana and Banff National Park in Canada, supporting one of the most diverse communities of carnivores and hoofed mammals in North America. Continue reading

New data to help manage predator-prey relationships
By Summit Voice
SUMMIT COUNTY — With European wolves slowly recovering from centuries of persecution, researchers have found distinctive feeding patterns that could help wildlife bioogists manage both prey and predator species.
Some European wolves show a clear preference for wild boar over other prey, according to a new study by scientists from Durham University, UK and the University of Sassari in Italy, who found that the diet of wolves was consistently dominated by the consumption of wild boar which accounted for about two thirds of total prey biomass, with roe deer accounting for around a third.
The study analyzed the remains of prey items in almost 2000 samples of wolf dung over a nine year period and revealed that an increase in roe deer in the wolf diet only occurred in years when boar densities were very low. In years of high roe deer densities, the wolves still preferred to catch wild boar.
The research team related the prey remains in wolf scat to the availability of possible prey in part of Tuscany, Italy – an area recently colonized by wolves.
“Our research demonstrates a consistent selection for wild boar among wolves in the study area, which could affect other prey species such as roe deer,” said lead author Miranda Davis, from the School of Biological and Biomedical Sciences at Durham University. Continue reading

Conservation advocates call for new introductions in northern Florida and Georgia
By Summit Voice
SUMMIT COUNTY — Wildlife conservation advocates say the record number of Florida panther deaths due to collisions with vehicles highlights the need to protect more habitat in Southern Florida.
Two more panthers were killed this past week, bringing the total for the year up to 26, or one every other week, on average. Continue reading

Pittman-Robertson Act crucial to maintaining Colorado game herds

SUMMIT COUNTY — Without much fanfare, wildlife managers around the country are celebrating a milestone this month, as the Pittman-Robertson Act turns 75.
If you’ve never heard of the Pittman-Robertson Act, you’re probably not alone, but if you value wildlife, you’ve probably benefited from what might is probably the single most effective funding tool for wildlife management and restoration.
Along with a companion measure — The Dingell-Johnson Act — passed several years later, the 11 percent excise tax on firearms and ammunition has helped restore charismatic species like wild turkeys, bald eagles and peregrine falcons. In Colorado, the funds have also been used to help pay for management and operations at 300 state wildlife areas. Continue reading
