Document Description
The California Department of Fish and Wildlife is issuing a permit to Betty Young [Permit No. 2081(a)-21-004-RP] pursuant to Fish and Game Code section 2081(a) for a project to preserve and propagate Vine Hill manzanita (Arctostaphylos densiflora) plants and seeds. Plants at the Vine Hill Preserve (Preserve) may currently be infected with the plant pathogen Phytophthora, which threatens the species with extinction. Cuttings must be taken to preserve the species and to retain the ability to outplant at new uninfected sites. The Project also includes treating the foliage of Vine Hill manzanita at the Preserve with potassium phosphite to prolong the survival of the infected plants and collecting one hundred percent of seeds for up to three years for long-term conservation storage and propagation to increase genetic diversity in future outplanted sites.
