Red Swamp Crayfish (Procambarus clarkii)

The Red Swamp Crayfish can spread rapidly in areas where they are invasive.

This non-native crayfish thrives in the waters of the Santa Monica Mountains, eating the eggs of amphibians, disrupting fragile fresh water environments and hosting a variety of unwelcome parasites. A noticeable decrease in amphibians has been attributed to crayfish predation. Crayfish are continually introduced to the Santa Monica Mountains because of their utilization as fishing bait.

What you can do!

Cease buying crayfish as fishing bait and encourage other fishers to do the same! Talk with local legislators to have crayfish banned as bait in the area and be sure to decontaminate all fishing equipment before entering the National Recreation Area.

Did You Know?

The need for plants used in restoration projects loomed large for many years, but volunteers made it happen.

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.
