A series of spatio-temporal models were built with decision tree regression on various spatial covariates (land cover, distance from physiographic features, geography) and temporal covariates (weather, time of night, time of season) with bat pass counts (at locations specified in the Bat Sites point layer) as the response. The covariate-specific responses identified by the models were then used to predict bat pass rates across the region based on spatial characteristics, under a set of static temporal conditions associated with above-average bat activity levels. The values of each shape indicate the predicted activity level on a relative scale, taking a categorical value from a range of 24 different values. The activity levels depicted represent all bats combined (all species).

The model is based on a set of spatial covariates and only explains a limited amount of the overall variation observed in bat pass counts. The full spatio-temporal model explains about 73% of overall variance, but the spatial patterns displayed here explain only 26% of the overall variance.</div><div><br /></div><div>The findings and conclusions in this dataset are those of the authors and do not necessarily represent the views of the U.S. Department of the Interior.
