MANAGING INVASIVE RED SWAMP CRAYFISH TO RESTORE STREAM HABITAT IN THE SANTA MONICA MOUNTAINS, LOS ANGELES COUNTY, CA.
For over 35 years, Mountains Restoration Trust (MRT), a public benefit 501(c)(3) land trust, has been conserving the natural and cultural resources of the Malibu Creek Watershed located in the Santa Monica Mountains. The presence of the invasive red swamp crayfish (Procambarus clarkii) is thought to have contributed to the local extirpation of the federally endangered California red-legged frog (Rana draytonii, CLRF) and reduction of Baja California tree frog (Pseudacris hypochondriaca) populations. MRT’s crayfish control strategy consists of three major components: management, research, and outreach/education. For management, MRT staff conducts daily trapping in target streams. For research, MRT has conducted benthic macroinvertebrate assessments and trap comparison studies to identify the most effective method for catching crayfish while limiting bycatch such as native fish, frogs and tadpoles. Finally, our education/outreach methods include facilitating volunteer participation in removal efforts and education via social media. This presentation will show case some interesting results from implementing MRT’s AIS strategy, including recent observations of CRLF in a crayfish-managed stream, suggesting that native species recovery is possible with a comprehensive AIS strategy.
