New and Ongoing Wildlife Mortality Events Nationwide

USGS and a network of partners across the country work on documenting wildlife mortality events in order to provide timely and accurate information on locations, species, and causes of death. This information is used by natural resource managers, researchers, public health officials, and legislators to help design disease prevention and mitigation strategies; to address interconnections between human, domestic animal, and wildlife disease; and to assist in identification of 'normal' disease issues vs. biosecurity concerns.

These data are not all-inclusive. Information on some outbreaks may not be received until months or years after the event, but efforts continue to make the information as complete as possible.

New These data are now available on the Wildlife Health Information Sharing Partnership - event reporting system (WHISPers), which has tools designed to query, map, sort, and download event data. WHISPers hosts data for both historic and ongoing wildlife mortality events.

For additional information on mortalities, contact the NWHC field epidemiology team at 608-270-2480 or
