This dataset tracks the distribution of California least tern colonies along the California Coast. Colonies are monitored annually during the nesting season and data is reported to California Department of Fish and Wildlife. This dataset provides specific site locations that's intended for California Dept. of Fish and Wildlife internal use only. Please also see public versions for public use, California Least Tern Monitoring Sites Generalized [ds3146] and California Least Tern Monitoring Sites by Region [ds3147].
California least tern colonies are monitored during nesting season along the California Coast and data is reported to California Department of Fish and Wildlife. The colonies in this dataset range from the Tijuana river mouth near the Mexico border to Sacramento. Locations and data include both present and historic sites. Locations are approximate and can have variation over time. Some additional sites without location information can be found in related table. The related table includes nesting data by year from 1990 - 2021. It's anticipated to update this dataset to include earlier and newer records. Monitoring data includes estimated fledglings, estimated breeding pairs, total number of nests, and predator information when included in site reports. Annual reports can also be found by searching in California Department of Fish and Wildlife's document library ( nrm.dfg.ca.gov/documents/docViewer.aspx ).
