Wildlife Health Event Reporter (WHER) is an online, experimental reporting system for reporting and sharing the sightings of sick or dead wildlife.

Individual reports viewed together can lead to the detection and containment of wildlife disease outbreaks that may pose a health risk to people, domestic animals and other wildlife. For smart phone users, the HealthMap mobile phone application, Outbreaks Near Me, is also available. It captures the same information that the web-based WHER application collects and allows users to upload photos. WHER hopes to harness the power of the many eyes of the public to better detect wildlife disease phenomenon.

Additionally, WHER was developed by the Wildlife Data Integration Network (WDIN), a program of the Nelson Institute for Environmental Studies at the University of Wisconsin-Madison, in partnership with the USGS National Wildlife Health Center.
