Non-native Species

Invasive Giant Cane thrives and depletes resources for native plants in many areas of the Santa Monica Mountains.

Non-Native Species pose a risk to the fragile Mediterranean habitats of the Santa Monica Mountains National Recreation Area.

Plants and animals that originated outside of California have made their way into the Santa Monica Mountains. These species are, in many ways, destroying the native species populations unique to this ecosystem. These “non-native” or “invasive” species out compete the locals for resources such as food, water or space, and demonstrate superior competitive abilities in areas influenced by human activity.

Plants

Seeds are tricky things! They can hide under shoe laces, backpack straps and even your dog! Avoid contaminating park land as well as your own home with pesky invasive, non-native plants.

Non-native plants comprise over 25% of the Santa Monica Mountains flora. Urbanization, increase in recreational activities and fire, amongst others, are factors that facilitate the introduction and spread of non-native species in the Santa Monica Mountains National Recreation Area.

You can help the park reduce the number of non-native plants introduced to park lands by checking your pets, recreational equipment and boots for stray seeds and fruits that are caught on fabric. Even visiting between areas within the park can spread unwanted invasive seeds!

Animals

Non-native animals can also be devastating to parklands. These animals can degrade natural habitats, prey on native species and off-set ecosystem balance. They can spread disease, non-native plant seeds and eat key predators or producers.
