null

Providing forest health technical assistance, training sessions, and technology transfer to:

  • Los Padres, Angeles, San Bernardino, and Cleveland National Forests
  • 2 National Monuments
  • 2 National Parks
  • 1 National Recreation Area
  • 1 National Preserve
  • Department of Defense lands
  • Many State Parks, ranging from the Central Coast south and inland, and ranging from beaches to high mountains and deserts.
  • 30 Indian Reservations

Unique Features

  • All four National Forests are managed primarily for recreation.
  • Portions of the service area comprise one of ten highest biodiversity hotspots at the global level.
  • Endemic forest tree species, including Pseudotsuga macrocarpa (bigcone Douglas-fir), Abies bracteata (Santa Lucia fir), and the rare Hesperocyparis forbesii (Tecate cypress) exist in this service area.
  • Two thirds of the human population of California lives within the service area, a total of 24 million people.
  • Much of the service area is subject to drought and density dependent tree mortality, proximally caused by bark beetle infestation.
  • The Coastal Ranges include areas infected with two exotic diseases: Phytophthora ramorum (sudden oak death) and Fusarium circinatum (pine pitch canker).
  • The busiest seaports in the United States are located in southern California, providing opportunities for importation of exotic pests.
  • Major native forest pests include Heterobasidion root disease, Arceuthobium spp. (dwarf mistletoe), Dendroctonus spp. (bark beetles), Ips spp. (pine engraver), and Melanophila californica (California flatheaded borer).
  • Other exotic pests include Agrilus auroguttatus (goldspotted oak borer) and Euwallacea sp. (polyphagous shot hole borer).
  • Urban forests are an important component in this service area due to the presence of large urban areas and extensive urban interface with public lands.
