Dennery Canyon Rare Plant Restoration

The goal of this project is to restore and enhance populations of four Management Strategic Plan (MSP) plant species and vernal pool habitat over a three-year period. Species directly benefiting from this effort include: San Diego thornmint (Acanthomintha ilicifolia), Otay tarplant (Deinandra conjugens), San Diego ambrosia (Ambrosia pumila), Orcutt's bird’s beak (Dicranostegia orcuttiana). The proposed project area encompasses approximately 8.68 acres. It provides a unique setting where the fours species co-exist with vernal pools not previously documented in the Vernal Pool Habitat Conservation Plan (VPHCP). Annual inspect and manage (IMG) monitoring results indicate increasing threats (primarily non-native weeds) are impacting MSP species populations in this area, and an intensive restoration effort is needed to ensure the long-term persistence of these species. Activities will consist of weed management, seed collection, seed bulking and redistribution, trash removal, vegetation monitoring, photo monitoring, and IMG monitoring. The proposed project will utilize the most current state of management knowledge along with Best Management Practices (BMPs) that have been successfully implemented in the region. This project is consistent with management objectives and actions in the MSP Roadmap, the MSP Framework Rare Plant Management Plan, and the MSP Seed Collection, Banking, and Bulking Plan. This project is partially funded by SANDAG TransNet EMP Land Management Grant #S1125503.
