Big brown bat (Eptesicus fuscus) capture records before and after white-nose syndrome

<p>We collated 30 years of big brown bat capture records collected between 1990 to 2020. We collected data from wildlife agencies and researchers in the eastern US. We kept capture records that fell within the months of March through October, representing spring through fall months when bats are surveyed outside of hibernacula. We then paired this data with spatiotemporal spread of the fungal pathogen <em>Pseudogymnoascus destructans</em> (causal agent of white-nose syndrome that kills North American temperate bats), of which, big brown bats are susceptible to infection. The completed dataset represents 30,497 individual big brown bat captures across 3,797 unique sites.</p>
