These data provide historical population estimates of known winter colony sites for all years from 2010 to 2021 for Myotis lucifugus, Perimyotis subflavus and Eptesicus fuscus and 2010-2023 for P. subflavus. These data were used to construct "winter-to-summer population connectivity metrics" which can be used as predictors of summertime bat occurrence and abundance in status and trends analyses. The first data set with all three species was used to create winter-to-summer connectivity metrics as predictive covariates when estimating summer abundance. The second data set (including only P. subflavus) was used to inform integrated species distribution modeling for P. subflavus (see Related External Resources). These data are not intended to infer bat population trends on their own, but rather, their primary purpose is to construct winter-to-summer connectivity metrics.
