(Los Padres NF), where the series has been mapped. Isolated stands may occur near springs, seeps and sheltered moist locations up to about 3200 ft (976 m) but Redwood often occurs in mixed hardwood forest stands at those elevations. Those hardwood associates include Tanoak (Lithocarpus densiflorus), Madrone (Arbutus menziesii), Canyon Live Oak (Quercus chrysolepis), Coast Live Oak (Q. agrifolia) and California Bay (Umbellularia californica). At lower elevations, shrub associates such as Blue Blossom (Ceanothus thyrsiflorus) and Chamise (Adenostoma fasciculatum) commonly occur. DF Pacific Douglas-Fir Series Pacific Douglas Fir (Pseudotsuga menziesii) is generally limited to northern, central and eastern California but occurs in scattered stands south to the Santa Ynez Mtns. (Los Padres NF) close to the coast. The series has been mapped in the Santa Lucia Range south of the Ventana Wilderness (Los Padres NF) in a limited area below about 3300 ft (1010 m). Conifer associates in this area are Redwood (Sequoia sempervirens) and Ponderosa Pine (Pinus ponderosa). Tanoak (Lithocarpus densiflorus), Madrone (Arbutus menziesii) and Canyon Live Oak (Quercus chrysolepis) usually are the main hardwood associates. DM Bigcone Douglas-Fir Series Bigcone Douglas Fir (Pseduotsuga macrocarpa) stands are found in the South Coast, Transverse and Peninsular Ranges from the Mt. Pinos region south and westward into the Central Coast area. This Series occurs very sparsely in the Central Coast area. On protected, mesic canyon slopes, Bigcone Douglas Fir is locally dominant with Canyon Live Oak (Quercus chrysolepis) as an associate at elevations as low as 1000 ft (305 m) or less up to 7000 ft (2135 m) or more over its range. It occurs intermingled with trees of the Mixed Conifer - Fir Series in its higher elevations such as Ponderosa Pine (P. ponderosa) and White Fir (Abies concolor). KP Knobcone Pine Series The Knobcone Pine (Pinus attenuata) Series occurs in both the Santa Cruz Mountains and the Santa Lucia Range. This closed cone species normally occurs in small, dense stands on xeric, shallow or serpentine soils. Individual trees or small groves representing xeric sites may occur within almost any pine or cypress Series, or the Canyon Live Oak Series or with chaparral species. This Series is a result of past disturbances (usually fire) and is mixed with Canyon Live Oak (Quercus chrysolepis), Black Oak (Q. kelloggii) and Gray Pine (P. sabiniana). Associated shrubs include Whiteleaf Manzanita (Arctostaphylos viscida), Shrub Interior Live Oak (Q. wislizenii var. frutescens), Wedgeleaf Ceanothus (Ceanothus cuneatus), Toyon (Heteromeles arbutifolia) and Manzanita (Arctostaphylos spp.). E-4 Region 5 Field Guide Appendix E: Existing Vegetation References and Codes PP Ponderosa Pine Series The Ponderosa Pine (Pinus ponderosa) Series occurs only within the Santa Lucia Range in the Southern Coast Province. Other conifers may be present but Ponderosa Pine is clearly dominant. It is confined to mesic slopes above chaparral species, but may occur withnin one-half mile of the coast. Ponderosa Pine mixes with Coulter Pine (P. coulteri) on these slopes. Other associates include Black Oak (Quercus kelloggii) and Canyon Live Oak (Q. chrysolepis). Occasionally, Jeffrey Pine (P. jeffreyi) and Sugar Pine (P. lambertiana) mix as individual trees among the Ponderosa Pine Series within the Santa Lucia Mountains. PM Bishop Pine Series Bishop Pine (Pinus muricata) can be found along the coast of San Luis Obispo and Santa Barbara Counties, as well as in the Channel Islands and coastal areas further north. This closed cone pine grows in a maritime climate from the immediate coast to 1200 feet (350m) elevation, generally on shallow, poorly drained and often-boggy soils. It occurs in pockets, especially on north-facing slopes, within the Annual Grass, Wet Meadows and Coastal Sage Scrub Series. Pygmy Cypress (Cupressus goveniana var. pigmaea) and Shore Pine (P. contorta var contorta) may be important associates within the Bishop Pine Series. PR Monterey Pine Series This Series, dominated by Monterey Pine (Pinus radiata), occurs naturally in three locations along the coast: Ano Nuevo Point, Monterey, and Cambria, although it has been planted throughout the world. It mixes with Coast Live Oak (Quercus agrifolia) and Pacific Douglas Fir (Pseudotsuga menziesii). Knobcone Pine (P. attenuata) and Madrone (Arbutus menziesii) may also be associated. Understory species include Bedstraw (Galium spp.) and Shaggy Barked Manzanita (Arctostaphylos tomentosa). Monterey Pine occurs in almost pure stands of even age due to regeneration and site dominance after fire.
