SENSITIVE SPECIES

We are not an endangered species ourselves yet, but this is not for a lack of trying.

– Douglas Adams

Sensitive species are those that have been listed as such by federal or state resource agencies, or by special interest groups such as the California Native Plant Society (CNPS). At least 49 sensitive species are known to occur within the Lagoon and adjacent uplands. These include 35 plants, 1 insect, 6 reptiles, and 5 birds.

SENSITIVE PLANT SPECIES

Sensitive plant species that have been observed in the Lagoon and adjacent uplands are summarized in the table below. The majority of these occur in upland habitats or at the wetland/upland transition. Most are considered rare, threatened, or endangered by the CNPS; however, three upland species are federally listed as endangered. Below are some key sensitive plant species found in Los Peñasquitos Lagoon and a comprehensive list of all of the sensitive species found in the Lagoon and nearby uplands.
