Agency efforts to educate visitors sometimes met with verbal abuse, according to federal biologists

FRISCO — Observations by U.S. Fish and Wildlife Service biologists may bolster a watchdog group’s arguments that well-intentioned swim-with-manatee programs are actually pushing the endangered marine mammals closer to the brink of extinction.
In some Florida locations, harassment of manatees by visitors may be out of control, according to Public Employees for Environmental Responsibility, which last month said it will go to court to try and end the programs.
An email written last year by outgoing Crystal River National Wildlife Refuge/ Kings Bay Manatee Refuge manager Michael Lusk may be a “smoking gun” that shows exactly how visitors are disturbing the animals. Without adequate resources to manage the swim-with-manatees programs, the activities are likely to contribute to the decline of the species. Continue reading

Feds propose ‘non-essential, experimental’ status

FRISCO — Black-footed ferrets could make a comeback on private lands in Wyoming under a federal proposal to designate the State of Wyoming as a special area for reintroduction, where the mammals would be managed as a “non-essential, experimental” population under a special provision of the Endangered Species Act.
The prairie-dwelling critters have been on the Endangered Species List since 1967. They were listed just a year after Congress passed the Endangered Species Act. Continue reading

Climate change to cut key nesting habitat in Wyoming
FRISCO — As if greater sage-grouse didn’t already have enough to worry about, a new study suggests that global warming may reduce nesting habitat for the dwindling birds by 12 percent in southwestern Wyoming by 2050.
“Historic disturbances of fire, development and invasive species have altered the sagebrush landscape, but climate change may represent the habitat’s greatest future risk,” said Collin Homer, the U.S. Geological Survey scientist who led the research.
“Warming temperatures, combined with less snow and rain, will favor species other than sagebrush, as well as increase sagebrush habitat’s vulnerability to fire, insects, disease and invasive species,” Homer said, explaining that the research helped show how vulnerable sagebrush landscapes are to climate change.

Logging and post-fire salvage, along with competion from barred owls, still seen as key threats
FRISCO — Dinged by a double whammy of continued habitat loss and interspecies competition, the Pacific Northwest’s northern spotted owl may get even more protection under the Endangered Species Act.
The U.S. Fish and Wildlife Service this week said it will launch a review to decide if the spotted owl should be reclassified as endangered rather than threatened.
The population of the northern spotted owl is declining across most of the species’ range. The most recent data show a 2.9 percent range-wide population decline per year, although declines as high as 5.9 percent per year have been observed in some areas. Continue reading

FRISCO — It took 100 years, but bighorn sheep have returned to high country of Yosemite and Sequoia National Parks, as federal and state biologists last month transplanted small herds of the mammals to their new homes.
Between March 26 and March 29, 2015, nine ewes and three rams were moved from the Inyo National Forest and Sequoia National Park to the Cathedral Range in Yosemite National Park. In addition, seven ewes were moved to the Laurel Creek area of Sequoia National Park, with plans to relocated three rams to that area.
The Sierra Nevada bighorn sheep is the only federally endangered mammal in Yosemite, Sequoia, and Kings Canyon. The species was listed in 2000 after the population plunged to just 100 individuals. Since then, the population has since increased to more than 600. Continue reading

New study explores climate change effect on hundreds of species
FRISCO — New research led by U.S. Forest Service scientists shows the scope of expected climate change impacts in Alaska’s arctic and subarctic regions.
The study concluded that 97 percent of the birds and mammals living in the region would feel could experience some form of habitat loss or gain because of climate change. In all, the researcher looked at 162 species of birds and 39 species of mammals. Continue reading
