context_page_description: The Santa Susana Mountains are a transverse range of mountains in Southern California, north of the city of Los Angeles, in the United States. The range runs east-west, separating the San Fernando Valley and Simi Valley on its south from the Santa Clara River Valley to the north and the Santa Clarita Valley to the northeast. The Oxnard Plain is to the west of the Santa Susana Mountains.
context_section_description: The south-facing slopes are mostly covered in Chaparral shrubland, grasslands, and oak savanna. The north-facing slopes are home to magnificent oak woodlands and conifer (fir) woodlands, some of which have been protected in the Santa Clarita Woodlands Park and other large open space preserves. The mountains are part of the California chaparral and woodlands ecoregion. The oaks, (Quercus spp.), include the evergreen coast live oak (Quercus agrifolia), the deciduous valley oak (Quercus lobata), and the coastal scrub oak (Quercus dumosa) all can be found in the area. Spring wildflowers include the redbush monkey flower, Mariposa lily, and canyon sunflower. Poison oak is also an important member of the native plant habitat community. Various ferns are found in moister and tree-shaded areas.
