Come help us remove crayfish from Medea Creek! Crayfish are a non-native species to California, and they're considered invasive because they cause quite a bit of damage to the aquatic ecosystems. They prey on native species, reduce water quality, and cause problems with creek bed erosion. We need your help in trapping and removing the crayfish as well as picking up trash along the stream.

This event is great fun for volunteers of all ages! Volunteers 12 years or younger must be accompanied by an adult. Volunteers under the age of 18 must bring the Parental Consent Form with a parent or guardian's signature if the parent or guardian is not attending.

Registration is free, but required. Registered volunteers will receive an email confirmation with more details.
