Species were identified that currently occur in LA County and are listed as endangered, threatened based on the Endangered Species Act. The list for all species came from searching the United States Fish and Wildlife Service (USFWS) 5-year plans by county (Los Angeles), which directs you to a table of the currently listed species. Species counts were determined from 2018 data on iNaturalist. Current statuses were confirmed using online databases of species records, including eBird and iNaturalist for vertebrates, the Consortium of California Herbaria for plants, and UCLA experts.
