Final Report for the Rice Canyon Sensitive Plant Species Management Project (SANDAG Grant Number 5005508; RECON Number 9429)

Type: report

Article abstract: The primary goal of the Rice Canyon Sensitive Plant Species Management Project (project) was to reduce the threat from invasive stinknet (Oncosiphon pilulifer) and illegal trespassing to sensitive plant species. Reducing these threats was a benefit to sensitive animal species that occupy Rice Canyon as well. Sensitive plant species that were the focus of the project include Otay tarplant (Deinandra conjugens), San Diego thornmint (Acanthomintha ilicifolia), and Orcutt’s bird’s-beak (Dicranostegia orcuttiiana). Sensitive animal species that also occur in Rice Canyon include coastal California gnatcatcher (Polioptila californica californica) and coastal cactus wren (Campylorhynchus brunneicapillus sandiegensis) among other Multiple Species Conservation Plan-covered species.
