Should federal forest management prioritize protecting sensitive animal habitats in public land planning?
NABat scientists have released updated occupancy maps for the Northern long-eared bat, a species found east of the Rocky Mountains. The new data incorporates the impact of white-nose syndrome to help prioritize survey areas for conservation.
Why it matters
These studies aim to provide forest managers with actionable insights to protect bat populations. By identifying preferred habitats, authorities can better implement strategies that support the recovery of these sensitive species.
Researchers analyzed habitat requirements for 4 specific bat species across the Eastern U.S. The findings highlight that prescribed fire benefits occupancy 1 year after implementation.
The players
USGS
The United States Geological Survey is a federal scientific agency that provides reliable information about the Earth and its ecosystems.
U.S. Forest Service
The U.S. Forest Service is an agency of the Department of Agriculture that manages public lands in national forests and grasslands.
U.S. Fish and Wildlife Service
This federal agency is dedicated to the management of fish, wildlife, and natural habitats for the benefit of the American people.
The details
The research, a collaboration between the USGS, U.S. Forest Service, and U.S. Fish and Wildlife Service, analyzed how different forest management techniques affect bats. The study found that thinning increases occupancy for all four species, whereas clear-cutting does not, and that all species prefer increased tree canopy cover.
Timeline
NABat scientists released the updated occupancy maps in 2026.
Roadmap
This study aligns with the broader federal push to integrate empirical mapping into compliance with the Endangered Species Act. It shifts conservation strategy from general land protection to specific, data-driven management techniques that boost species occupancy.
Visitors to national parks and federal forests may encounter updated signage or restricted trail access in newly identified priority survey areas. These management changes are designed to support the recovery of local bat populations while maintaining safe public recreation.
The takeaway
The research confirms that strategic forest management, specifically thinning and prescribed fire, can significantly improve habitat viability for bats. Effective conservation now relies on applying these specific techniques rather than relying on blanket environmental policies.
