Plants

Pond at Rancho Sierra Vista / Satwiwa

The Santa Monica Mountains are home to 12 vegetation communities, which are derived from 26 vegetation associations identified by the California Natural Diversity Database classification system (Holland 1986). These include coastal salt marsh, coastal strand, coastal sage scrub, chaparral, coast live oak woodland, riparian woodland, valley grassland, valley oak savanna, freshwater ponds/lakes, rock outcrops, and suburban development.



Vegetation communities are determined by the following factors: presence of water, elevation, aspect, soil, proximity to the ocean, and presence or frequency of fire.

Euphorbia teracina or Terracina Spurge grows rapidly and is a prolific seed producer, easily invading coastal scrub lands and out-competing native species for space.

However a battle to protect this ecosystem from invasive plants is being waged in the mountains. Noxious invasives commonly called weeds are still spreading through out the Santa Monica Mountains. Early dectection is key in preventing large ecosystem impact.

Four state parks were the triumph of a grassroots movement to protect open spaces minutes from Los Angeles in the 1950s & 60s. Three women, Sue Nelson, Jill Swift, and Margo Feuer further galvanized the movement that helped make Santa Monica Mountains National Recreation Area a reality in 1978.
