The federally and state endangered least Bell's vireo and the federally threatened coastal California gnatcatcher
have been recorded on campus.
The land also supports the threatened coastal California gnatcatcher
, and a variety of sensitive plants, such as the Moreno currant and the San Diego milkvetch.
Several of the earliest banks were developed in the conservation planning area of a Natural Community Conservation Plan in Southern California to protect coastal sage scrub habitat of the threatened California gnatcatcher
among other species.
The niche exploitation pattern of the blue-gray gnatcatcher
Our management of inland ecosystems, including coastal sage scrub and riparian areas, has benefited the Quino checkerspot butterfly (Euphydryas editha quino), arroyo toad (Bufo californicus), coastal California gnatcatcher
(Polioptila californica californica), least Bell's vireo (Vireo bellii pusillus), and Stephens' kangaroo rat (Dipodomys stephensi).

Among other migratory passerines, densities exceeded 1 individual/ha at all three sites for Eastern Wood-Pewee, Acadian Flycatcher, Wood Thrush, Great Crested Flycatcher, Indigo Bunting, Blue-gray Gnatcatcher
, and Red-eyed Vireo (Table 3).
The California gnatcatcher
could lose as much as 56% of its range, or as little as seven percent, depending on how climate change is addressed.
The species infected were a great blue heron (Ardea herodias), 2 American crows (Corvus brachyrhyncos), 2 American robins (Turdus migratorius), 2 mourning doves (Zenaida macroura), a red-tailed hawk (Buteo jamaicensis), a blue-gray gnatcatcher
(Polioptila caerulea), a northern mockingbird (Mimus polyglottos), a house finch (Carpodacus mexicanus), and a northern cardinal (Cardinalis cardinalis).

(Polioptila californica californica), golden-checked warbler (Dendroica chrysoparia), Hawaiian stilt (Himantopus mexicanus knudseni), least Bell's vireo (Vireo bellii pusillus), Mexican spotted owl (Strix occidentalis lucida), red-cockaded woodpecker (Picoides borealis), southwest willow flycatcher (Empidonax traitlii extiraus), western snowy plover alexandrinus nivosus), desert tortoise (Gopherus agassizii), gopher tortoise (Gopherus polyphemus), green sea turtle (Chelonia mydas), loggerhead sea turtle (Caretta caretta), gray bat (Myotis grisecens), Indiana bat (Myotis sodalis), and Sonoran pronghorn (Antilocapra americana sonoriensis).
Best bets: The dry chaparral habitat on the southeast side of Mount Pisgah attracts species that are unusual in this area, including blue-gray gnatcatcher
and California towhee.
The critical habitat for the Arroyo toad, (2) the Riverside fairy shrimp, the California gnatcatcher
, and the tidewater goby (originally designated in 2000) covered a large swath of coastal sage scrub and other grasslands, vernal pools, rivers, and streams of southern California.
