Starting in 2021, surveys were conducted on suitable habitat on Conserved Lands to document whether historic plant occurrences were extant and to discover new occurrences for rare plant species. The purpose of these surveys is to refine and update the distribution of these plants in the Management and Monitoring Strategic Plan Area. Voucher specimens and photographs are taken for each occurrence. Some species are already part of the Rare Plant Inspect and Manage Program and any new occurrences for these species will be included in future monitoring. In the next update of the Management and Monitoring Strategic Plan (2027), species not formerly monitored will be evaluated and potentially added to the Rare Plant Inspect and Manage Program. Botanists surveyed for four rare plant species in 2021: San Diego coastalcreeper (Aphanisma blitoides), Blochman's dudleya (Dudleya blochmaniae), coast wallflower (Erysimum ammophilum), and Orcutt's bird's-beak (Dicranostegia orcuttiana). In 2022, botanists surveyed for: San Diego coastalcreeper (Aphanisma blitoides), Baja California oat grass (Sphenopholis interrupta ssp californica), San Diego ambrosia (Abrosia pumila), Wiggins' cryptantha (Crytantha wigginsii). In 2023, botanists will survey for five rare plant species: Deane's milkvetch (Astragalus deanei), Parish brittlescale (Atriplex parishii), Mexican flannelbush (Fremontodendron mexicanum), Jennifer's monardella (Monardella stoneana ), and small-leaved rose (Rosa minutifolia).
