Non-native plants comprise over 25% of the Santa Monica Mountains flora, a figure higher than the overall average of California. The problem is exacerbated by urbanization and the increasing recreational use of the mountains, which contributes to disturbances, including fire. These disturbances facilitate the introduction and spread of non-native plants. Many of these "alien" plants originate in the Mediterranean basin and northern Europe and have demonstrated superior competitive abilities in human-influenced environments. Non-native plants present a profound threat to the integrity of native communities. Invasive non-native plants can displace native species, degrade wildlife habitat, and alter ecosystem functioning.
Did You Know?
A core group of dedicated National Park volunteers, often laboring in the hot sun, built a native plant nursery from the ground up in 2002. Native plants, from the common Ceanothus to the endangered Lyons pygmy daisy germinated in this volunteer-run nursery will help restore disturbed habitat.
