Species Data Explorer

The USFWS Environmental Conservation System (ECOS) houses downloadable species reports for listed species managed by FWS. CSI has compiled several of these reports to create a searchable database to view species attribute information. CSI will update this database twice a year to keep up with species range changes, new listings and listing changes.
