Status and Trends Program

Bats

North American bats face unprecedented threats including habitat loss and fragmentation, white-nose syndrome, wind energy development, and climate change. 

It is difficult to evaluate impacts of these threats because there is a lack of basic information about the distribution and abundance of bats across the continent. A statistically robust and standardized bat monitoring program across North America would help managers estimate extinction risk, set conservation priorities and evaluate the effectiveness of conservation actions.

We are collaborating with federal agencies, states and non-governmental organizations to develop and implement the North American Bat Monitoring Program (NABat).

  • NABat is an international interagency program designed to monitor bat distributions and abundances on public and private lands, and provide trend data at the state, provincial, tribal, regional (e.g., Landscape Conservation Cooperatives), and range-wide scales.
  • The goal of NABat is to provide natural resource managers with information they need to manage bat populations effectively, detect early warning signs of population declines, and estimate extinction risk.
  • NABat will allow state, provincial and federal agencies to better prioritize limited resources, engage in cross-agency collaboration, and involve the public in monitoring and conservation activities.

Bat Research in California

The primary goal of this bat research program is to develop projects that increase our understanding of basic ecology and natural history of western bat species, while simultaneously providing needed data to inform conservation measures and management decisions in the West. Dr. Brian Halstead, together with Gabriel Reyes, studies the habitat and resource selection, movement ecology, demography...
