Article abstract: The Spring Canyon/Goat Mesa vernal pools complex (J16-18) were identified by the adopted Recovery Plan for Vernal Pools of Southern California (USFWS 1998) as necessary to stabilize populations of the following endangered and threatened species: E. aristulatum, P. nudiuscula, N. fossalis, O. californica, B. sandiegonensis, and S. woottoni. The Management Strategic Plan for Conserved Lands in Western San Diego County (SDMMP) also lists other MSP species historically found onsite at Spring Canyon/Goat Mesa including D. variagata, M. minimus, S. hammondii, and A. cunicularia. Otay Mesa/Goat Mesa Open Space has also had recent recorded occurrences of Western Burrowing Owl, including a pair of owls observed using artificial burrows as recently as December 29, 2017 before the grant project started.
