A bat displaying signs of white-nose syndrome — a fungal disease that, according to the National Park Service (NPS), has killed millions of U.S. bats since its discovery in 2006. Dr. Mark Spond, Appalachian State University’s liaison to NPS, recently conducted studies of bats along North Carolina’s Blue Ridge Parkway as part of an NPS grant-funded project — data from which will help expand NPS knowledge of the parkway’s rare and WNS-affected bat populations.

BOONE, N.C. — With grant-funded assistance from Appalachian State University, the National Park Service (NPS) is expanding its knowledge of rare bat species found along North Carolina’s Blue Ridge Parkway, as well as parkway species that may be infected with white-nose syndrome (WNS) — a fatal fungal disease that has killed millions of U.S. bats to date, according to NPS.
Dr. Mark Spond, App State’s liaison to NPS and a faculty affiliate in the Department of Geography and Planning, was awarded $19,098 in NPS grant funding along with $5,589 in matching funds from App State for the project, which included conducting several studies to collect information on bat populations in the Blue Ridge Parkway area.
For the project, which took place from January–September, Spond collaborated with NPS Wildlife Biologist Bob Cherry and App State student researcher Chloe Dorin ’20, of Raleigh. Spond said Dorin’s efforts for the project were completed earlier this year, pre-COVID-19.
In addition to the overarching aim of learning about the parkway’s rare and WNS-affected bat species, Spond said the project’s two other goals were as follows:
- Educate the public and Blue Ridge Parkway staff about WNS in bats.
- Help protect bats that reside in the parkway area by knowing their locations and ensuring steps are taken in all parkway projects to protect bat roosts and hibernacula (where bats shelter while dormant during the winter).
The research team followed protocols set by the North American Bat Monitoring Program to conduct driving acoustic surveys along 20-mile sections of the Blue Ridge Parkway. During these surveys, an acoustic detection system mounted to the roof of the team’s vehicle was used to record the bats’ calls, or ultrasounds — sounds with a wave frequency higher than the human ear can detect.
The team also set out stationary survey microphones along the parkway, in coordination with the driving routes, and conducted stationary acoustic surveys at additional significant biological areas, in developed areas and at known bat roosts along the parkway.
After all surveys were performed, Spond and Dorin helped with managing and analyzing the collected data.
Dorin, who is a graduate student in the university’s Master of Science in biology degree program, holds a Bachelor of Science in biology from App State.
More about WNS and bat conservation
“Though often feared and loathed as sinister creatures of the night, bats are vital to the health of our environment and our economy as pest control, pollinators and seed dispersers,” the U.S. Fish and Wildlife Service (FWS) website states.
According to FWS — which works to protect and raise awareness of bats and also research WNS treatments — recent studies estimate bats eat enough insects to save more than $1 billion per year in crop damage and pesticide costs in the U.S. corn industry alone. Additionally, the FWS website states that across all U.S. agricultural production, consumption of insect pests by bats results in a savings of more than $3 billion per year.
The particular fungus that causes WNS, Pseudogymnoascus destructans, is likely exotic, having been introduced to North America from Europe, according to NPS.
Spond said of the 12 confirmed bat species that inhabit the Blue Ridge Parkway corridor, nine have been affected by WNS.
The NPS website states, “Researchers call the disease ‘white-nose syndrome’ (WNS) because of the visible white fungal growth on infected bats’ muzzles and wings. This cold-loving fungus infects bats during hibernation, when the bats reduce their metabolic rate and lower their body temperature to save energy over winter.
“What started in New York in 2006 has spread to more than half of the United States and five Canadian provinces by August 2016, leaving millions of dead bats in its path. WNS causes high death rates and fast population declines in the species affected by it, and scientists predict some regional extinction of bat species.”
