Notes
|
Only three native stands in CA, at Ano Nuevo, Cambria, and the Monterey Peninsula; introduced in many areas. Only one-half of the species' historical extent remains undeveloped on the Monterey Peninsula, and forest destruction has been unevenly distributed over different geomorphic surfaces. Threatened by development, genetic contamination, pine pitch canker disease, and forest fragmentation, especially at Del Monte Forest (MNT Co.) and in SLO Co.; seriously threatened by feral goats on GU Isl. Plants from BA (Cedros Isl.) and GU Isl. are genetically distinct. See Fremontia |
