Article abstract: Introduction: San Diego thornmint (Acanthomintha ilicifolia) is an endangered plant species that is found in clay soils within the County of San Diego. It is an annual herb that blooms between April and June. The surveys conducted are listed in Table 1 below. The methodology and results of the monitoring are detailed below. The goal of the effort was to continue long-term monitoring of San Diego thornmint under the Multiple Species Conservation Program (MSCP). McMillan Biological Consulting also conducted baseline surveys in May 2001 for the Otay Lakes population. Monitoring data for these baseline surveys is currently being compiled and will be available in late 2001. Previous surveys have been conducted by MSCP staff, Mike Kelly, and other volunteers in Sabre Springs, Black Mountain, and Peñasquitos Canyon. Additional surveys in Peñasquitos Canyon and Sabre Springs were also conducted by Ogden Environmental (1993).
