A world without abalone?
Improved hatchery spawning and rearing may help rebuild populations
FRISCO — West Coast fisheries biologists say they’re making progress toward restoring abalone populations with improved laboratory spawning and rearing. If the shellfish can withstand the effects of ocean acidification, resource managers may be able to rebuild populations off the coast of California. Continue reading

FRISCO — Almost 15 years after listing lynx as a threatened species, the U.S. Fish and Wildlife Service still hasn’t developed a recovery plan for the snow-loving cats, but a required five-year status review currently under way may help the process.
The review is aimed at clarifying the extent, magnitude, and nature of the threats to lynx so that recovery planning can target those specific threats. When lynx were originally listed in 2000, federal biologists said the lack of adequate regulations on public lands was the main threat to the predators. Continue reading

Population still near historic lows
FRISCO — Monarch butterfly populations may have rebounded a bit this year, according to the annual overwintering count, but the species is still going to need help to recover, conservation advocates say, urging the U.S. Fish and Wildlife Service to give the colorful insects Endangered Species Act protection.
This year’s count estimated that 56.5 million monarchs are currently gathered in Mexico for the winter, up from last year’s lowest ever total of 34 million. But that’s still more than 80 percent below the 20-year average and down 95 percent from numbers tallied in the mid-1990s. Near-perfect conditions during breeding season helped bolster the numbers this year. Continue reading

Activists again decry hunting, trapping in Northern Rockies

FRISCO — Wildlife conservation advocates want the federal government to rethink its wolf recovery efforts. Instead of relying on a piecemeal, state-by-state approach, the species needs a national recovery plan to help restore populations in places like the southern Rockies and the Adirondacks, according to Kierán Suckling, director of the Center for Biological Diversity
“A congressional end run around science and the Endangered Species Act will create more controversy and put wolves and the law itself in jeopardy,” said Suckling, explaining why a coalition of conservation groups this week petitioned the U.S. Fish and Wildlife Service to reclassify gray wolves as threatened, rather than endangered, under the Endangered Species Act.

Just 50 Sierra Nevada red foxes remain in the wild

FRISCO — One of the rarest mammals in the American West may be making a comeback in the Sierra Nevada. Yosemite National Park biologists this week confirmed a sighting of a Sierra Nevada red fox in the northern reaches of the park — the first the speices has been seen in Yosemite for nearly 100 years.
“We are thrilled to hear about the sighting of the Sierra Nevada red fox, one of the most rare and elusive animals in the Sierra Nevada,” said Yosemite National Park Superintendent Don Neubacher. “National parks like Yosemite provide habitat for all wildlife and it is encouraging to see that the red fox was sighted in the park.”
The U.S. Fish and Wildlife Service has been considering endangered species protection for the species since late 2011. There are only two known populations, one near Mt. Lassen and the other near Sonora Pass, just north of Yosemite, with a total population estimated at about 50 individuals. Continue reading

SW Colorado field project will assess habitat occupancy, population trends
FRISCO — Colorado biologists have launched an ambitious monitoring program aimed at learning whether the state’s population of reintroduced and native-born lynx is holding steady.
The monitoring will cover more than 5,000 miles in the San Juan Mountains in southwest Colorado, including six wilderness areas: Weminuche, Uncompahgre, Lizard Head, Powderhorn, La Garita Mount Sneffels, and South San Juan. Continue reading

Wildlife advocates seek wider restoration
By Summit Voice
FRISCO — Despite polls showing widespread public support for relocating Yellowstone bison to start herds in appropriate locations across the state, the National Park Service has once again started rounding up wild bison for slaughter.
The animals wander out of the park each winter searching for food at lower elevations. This year’s killing program is slated to be the largest in seven years to cap the bison population in the park at 3,500, part of a settlement with the state of Montana over now-discredited concerns about brucellosis and carrying capacity.
The late-December poll showed that 67 percent of Montanans support relocating Yellowstone bison rather than killing them. It also also found that 68 percent of Montanans view bison as wildlife and 72 percent believe bison should be managed like the state’s other wildlife species. Continue reading
