A fungal pathogen that has wiped out bat populations across the eastern third of the U.S. has now been found in Texas, according to state wildlife officials, who documented the fungus for the first time on two new bat species: the cave myotis and a western subspecies of Townsend’s big-eared bat.
White-nose fungus first emerged in 2006 in New York and his since spread into 30 states and killed at least 5.5 million bats. Wildlife conservation advocates said the recent announcement from is a biological disaster, considering the potential risks to huge, world-famous bat colonies that thrive in unique cave ecosystems in the state.

Toxic lead is back on the menu for many wildlife species, as newly appointed Interior Secretary Ryan Zinke revoked a U.S. Fish and Wildlife Service order that had banned lead hunting ammunition on federal wildlife reserves after a years-long campaign by wildlife advocates.
The USFWS order was finalized the day before Donald Trump was inaugurated as president. In his reversal, Zinke made no reference to the extensive body of science showing that lead ammunition is harmful to wildlife.
The threat of roads to carnivore species around the world has been seriously underestimated, according to a new study that looked at the issue on a global scale.
After looking at 232 carnivore species around the world (out of a total of about. 270 existing species) and assessing how severely these are affected by roads cut through their habitat, the researchers concluded that some rare species are even at risk in areas with low road densities. The study, published in the journal Global Ecology and Biogeography, calculated natural mortality rates, reproduction and carnivore movement patterns, determining the maximum density of roads that a species can cope with.

Small hibernating bat colonies need protection to prevent extinction
Between collisions with wind turbines and deadly white-nose syndrome, endangered Indiana bats may not have much of a chance of recovering, according to a recently published U.S. Geological Survey study.
Federal biologists say they can boost the population of grizzly bears in the North Cascades ecosystem by relocating the predators from other areas. The National Park Service and the U.S. Fish and Wildlife Service this week released a draft plan (open for public comment), for increasing the total number of bears in the region to 200. Bt current estimates, only about 10 remain, too small a population to sustain itself. According to the draft plan, grizzly bears could be relocated from either northwestern Montana or south-central British Columbia.
“We’re happy to see the agencies taking a step in the right direction to restore grizzly bears to the North Cascades,” said Andrea Santarsiere, a senior attorney with the Center for Biological Diversity. “Without a helping hand, grizzly bears are likely to disappear from the Pacific Northwest.” Continue reading “Feds eye grizzly reintroduction in North Cascades”→
With perhaps fewer than 100 vaquitas remaining in the Gulf of California, conservation experts say they will start a last-ditch recovery effort by trying to capture several of the marine mammals and keeping them in a temporary sanctuary. The emergency action plan will be led by the Mexican government and supported by a consortium of marine mammal experts from more than a dozen organizations around the world.
Despite substantial efforts by the Mexican government to protect vaquitas, the recovery team recently reviewed the latest results from advanced acoustic monitoring technology that showed the vaquita population continuing to rapidly decline.
“We are watching this precious native species disappear before our eyes,” said Rafael Pacchiano, Mexico’s secretary of the environment and natural resources. “This critical rescue effort is a priority for the Mexican government and we are dedicated to providing the necessary resources in order to give the plan its best chance of success.” The plan will be implemented in tandem with ongoing efforts to remove the threat of gillnets in the Upper Gulf of California and eliminate illegal fishing.

A federal recovery plan for endangered polar bears won’t halt the threat of climate change, but it could help dwindling populations of the great Arctic predators persist in the small patches of habitat that will remain after global warming melts most of the polar sea ice.
The plan, released Jan. 9, calls for reducing human-bear conflicts, collaboratively managing subsistence harvest, protecting denning habitat, and minimizing the risk of contamination from oil spills. Most of these actions are already underway, in partnership with Alaska Native communities, nonprofit groups, and industry representatives who participated in the plan’s creation. The plan also calls for increased monitoring and research. Continue reading “Feds finalize polar bear conservation plan”→
