10 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.

14 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

15 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 distributions and abundances

16 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

18 The Process Collaborative International Series of 4 workshop

19 Targeted Species 47 Species – Common to US, Canada, Mexico

20 Monitoring Methods Acoustic Surveys – Mobile Transects – Stationary Points Colony Counts – Hibernacula – Maternity Colonies

21 Sampling Design- 10 x 10 km grid

22 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

23 Sampling Design Any subset of grid cells is also random and balanced Can “over-sample” DoD lands

24

25 Response Design

26 Respose Design-Acoustics km transect -2 nights point surveys -4 nights

27 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

28 Implementation

30 Grid Assignment Example

31 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?

32 Data Management Bat Population Data (BPD) Project – USGS, Fort Collins – https://my.usgs.gov/bpd/ https://my.usgs.gov/bpd/

33 Data Management Data Partnerships – Allow NABat access – Restrict other access

34 Analysis & Products Plan General Technical Report Analyses – State, regional, and rangewide analysis – Distribution & abundance State of North American Bats Report
