White-nose syndrome has been spreading through U.S. bat populations since 2006 and has caused mass die-offs in various regions of the country. The syndrome is caused by Pd (Pseudogymnoascus destructans), a fungus that invades the skin of bats while they hibernate. USDA Forest Service wildlife biologists Roger Perry and Phillip Jordan conducted a study to calculate the survival rates of tricolored bats (Perimyotis subflavus) in the Ouachita Mountains of west-central Arkansas. The research helps satisfy the need for robust estimates of population data amid the WNS outbreak. The scientists chose to study the tricolored bat because it is common across North America and has suffered substantial declines due to WNS. The research highlights the importance of maintaining and protecting small hibernation sites as they may be critical to the conservation of the tricolored bat species.

The Bureau of Land Management has released the final programmatic environmental impact statement for fuels reduction and rangeland restoration in the Great Basin. This programmatic environmental impact statement (PEIS) is intended to further efforts to conserve and restore sagebrush communities within a 223 million-acre area that includes portions of Idaho, Oregon, Washington, California, Nevada and Utah.
Sagebrush communities in the Great Basin are a vital part of Western working landscapes and are home to over 350 species of plants and wildlife. Intact sagebrush communities are disappearing within the Great Basin due to increased large and severe wildfires, the spread of invasive annual grasses, and the encroachment of pinyon-juniper. The Great Basin region is losing sagebrush communities faster than they can reestablish naturally. Fuels reduction and rangeland restoration treatments can reduce fire severity, increase sagebrush communities' resistance to invasive annual grasses and improve their ability to recover after wildfires.

Cattle grazing on a nearly half mile wide targeted strip of cheatgrass near Beowawe, Nevada, created a firebreak that helped limit a rangeland fire to just 54 acres this past August compared to rangeland fires that more commonly race across thousands of acres of the Great Basin. This "targeted grazing" firebreak and eight others are part of an evaluation project being managed by the Agricultural Research Service (ARS), partnering with other federal, state and local agencies and local cattle ranchers in Idaho, Nevada and Oregon. These demonstration sites are being studied so the concept's efficacy and environmental impacts can be uniformly evaluated and compared.
Cheatgrass, also known as downy brome, is an invasive annual that dominates more than 100 million acres of the Great Basin in the western U.S. Germinating each winter, cheatgrass grows furiously in spring and dies in early summer, leaving the range carpeted in golden dry tinder. The Great Basin now has the nation's highest wildfire risk, and rangeland fires are outpacing forest fires when it comes to acreage destroyed.
