The California Department of Fish and Wildlife is issuing a California Endangered Species Act (CESA) permit to The Land Conservancy of San Luis Obispo County (Permit No. 2081(a)-23-010-RP) pursuant to Fish and Game Code section 2081(a) for a project to establish a new population of marsh sandwort (Arenaria paludicola) and La Graciosa thistle (Cirsium scariosum var. loncholepis) at Black Lake Ecological Area. Propagated marsh sandwort plugs will be installed in 2024 along the shore and on top of floating islands. Maternal lines will be tracked, and planting locations will be recorded using global positioning service (GPS). Propagated La Graciosa thistle plants will be installed on the western edge of Black Lake in 2024. The Permittee will record the GPS location of each seedling and will monitor individuals for successful seed production. Vegetation management will occur year-round following outplanting to ensure invasive species competition is minimized. A formal rare species survey will be conducted prior to any on-site maintenance activities. Herbicide treatments may be conducted within the vicinity of plantings and will include an herbicide buffer zone of no less than 15 feet (more often 25 feet) around any marsh sandwort or La Graciosa thistle plants. Vegetation management within the buffer zone will be restricted to mechanical string trimming, hand weeding, or removal using hand tools. A formal survey will be performed at the end of the growing season each summer to record the number of marsh sandwort and La Graciosa thistle plants, the survey date, the geographic location of each plant found, and the plant’s status. The Permittee will monitor the outplanted populations for a minimum of five consecutive years to determine presence, absence, population contraction or expansion, and to evaluate the ecological tolerances of the species to natural occurrences of heat, frost, flooding, and drought. Water quality data (e.g., pH, conductivity, temperature, and dissolved oxygen) will be collected annually in the fall.
