Conserving trees for endangered bats

Tricolored bats (Perimyotis subflavus) in South Carolina are threatened by habitat loss and white-nose syndrome. New research shows where they roost during winter, and where they and northern yellow bats (Lasiurus intermedius) roost in summer. Northern yellow bats are considered a species a special concern in South Carolina. USDA Forest Service scientist Susan Loeb contributed…  More

When Detecting Bats, Methods Matter

If you want to record bat calls in summer, go early. Detectors recorded significantly more high-quality call files during late June and early July than August. USDA Forest Service research ecologist Susan Loeb and colleagues published results from a bat detection survey in Acta Chiropterologica. The likely reason bats had very high recorded activity in…  More 

One Treatment Does Not Fit All Sizes

Bats are important components of healthy forests and provide critical ecological services across numerous different ecosystems. For decades, bat populations throughout the southern U.S. have been declining due to habitat disturbance and loss. USDA Forest Service scientist Susan Loeb contributed to two recent publications to address this issue, suggesting ways to improve bat management practices…  More 

Which Bat Is That? The Smell Will Tell

For the first time, people can distinguish one bat species from another by smell alone. Scientists from the USDA Forest Service and Arkansas State University found that a new, portable electronic nose (e-nose) device is capable of distinguishing between bat species by their smells. This study is part of a larger effort to help bats…  More 

Forests for Bats

“Almost all North American bats rely on forests for survival,” says Roger Perry, USDA Forest Service research wildlife biologist. Perry recently led the team that updated Forest Management and Bats, a booklet designed for private landowners and anyone managing forests. It was first published in 2006 by Bat Conservation International, and Daniel Taylor of BCI…  More 

Bat Survival in Arkansas Mines

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. White-nose syndrome (WNS) symptoms include dehydration and irritation. These symptoms awake the bats frequently…  More 

Green Line Meeting in Arkansas Promotes Collaboration

On September 10, a Green Line meeting brought USDA Forest Service researchers and managers together, along with state partners. Participants represented the Southern Research Station, the Ouachita National Forest, the Ozark National Forest, and the Arkansas Forestry Commission. Twenty-eight people attended the meeting, including leadership from SRS, the Southern Region and Arkansas state forester Joe…  More 

Research for Mississippi and Beyond

Water defines the Mississippi Delta, an alluvial plain in northwest Mississippi. The Delta is sandwiched between the Yazoo and Mississippi Rivers, and a network of levees and pumps aim to keep the land dry enough for habitation and agriculture. In 2019, however, historic flooding left fields inundated for months. USDA Forest Service scientists have served…  More 

Can Southeastern Bats and Rock Climbers Share Cliffs?

“Researchers haven’t really studied cliffs as foraging areas for bats,” says USDA Forest Service scientist Susan Loeb. “When so little is known about that habitat, it can be hard to gauge the impacts of different uses or management plans.” Rapid growth in technical climbing has put rock climbers in the same spots as bats. How…  More
