The Need to Monitor 1) Bat Banding Program (BBP) US Biological Survey/USFWS 2) Endangered Species Monitoring 3) Estes Park
National Plan Working Groups Goal 1: Develop and validate rapid-assessment monitoring plans to determine differences in susceptibility among species, and identify which species are most vulnerable to extinction due to WNS.

North American Bat Monitoring Program -- NABat Vision: A coordinated effort that promotes effective decision-making and long-term viability of NA bats Mission: Provide architecture for coordinated bat monitoring to support local, regional and range-wide inferences about trends in bat populations and abundances

NABat Fundamental Question: How do trends in NA bat distributions & abundances vary over geographic extents and time periods in relation to WNS, wind energy, CC & conservation actions? Application: Evaluation of extinction risk and population status at local and regional scales to support conservation planning

The Process • Collaborative • International • Series of 4 workshop
Targeted Species • 47 Species • Common to US, Canada, Mexico
Monitoring Methods • Acoustic Surveys • Mobile Transects • Stationary Points • Colony Counts • Hibernacula • Maternity Colonies
Sampling Design • Generalized Randomized Tessellation Stratified (GRTS) Sample • Spatially balanced approach • Flexible • Grid cells can be dropped for logistical reasons • Grid cells assigned weights or inclusion probabilities • Can include some samples outside design
Sampling Design • Any subset of grid cells is also random and balanced • Can “over-sample” DoD lands
Respose Design-Acoustics --25-48 km transect -2 nights --2-4 point surveys -4 nights
Response Design-Colony Counts • Short-term approach • Strengthen current monitoring efforts by states • Standardized protocols & co-variates • No attempt to fit into grid • Long-term approach • Use grid to search for new colonies
Caveats/Concerns • Acoustic identification • Many models, which is correct? • Metadata • Archive original data • Robustness to false +’s and –’s? • Unknown hibernacula • Particularly in western NA • Better/alternate analyses?
Data Management • Bat Population Data (BPD) Project • USGS, Fort Collins • https://my.usgs.gov/bpd/
Data Management • Data Partnerships • Allow NABat access • Restrict other access
Analysis & Products • Plan General Technical Report • Analyses • State, regional, and rangewide analysis • Distribution & abundance • State of North American Bats Report
