The Mediterranean Coast Network Inventory & Monitoring Program oversees the terrestrial herpetofauna monitoring protocol. The protocol is being implemented at the following parks:

Cabrillo National Monument
Monitoring was initiated at Cabrillo National Monument and the Point Loma peninsula in 1995 by the United States Geological Survey (USGS) using pitfall trap methodology. Pitfall trap arrays consist of bucket traps (pits) embedded in the ground connected by “drift” fencing. Funnel-shaped snake-traps are laid alongside the fence line. On the Point Loma peninsula, 16 pitfall trap sampling sites were chosen to represent a variety of habitats. Arrays are visited monthly for five consecutive days. Learn more

Channel Islands National Park
A series of cover boards along transect lines are used to monitor five terrestrial herpetofauna species (Pacific slender salamander, Western fence lizard, side-blotched lizard, Southern alligator lizard, and island night lizard) on three of the five park islands (Anacapa, Santa Barbara and San Miguel Islands). Six permanent transect lines have been established and are monitored annually during the spring and fall seasons. Learn more

Santa Monica Mountains National Recreation Area
In 2000, Santa Monica Mountains National Recreation Area implemented the same monitoring scheme as Cabrillo National Monument using pitfall trap methodology. 80 sampling sites were chosen, 20 from the previous inventory effort and 60 randomly assigned sites representing a variety of habitats throughout the Santa Monica Mountains and Simi Hills. Pitfall trap arrays are visited bi-weekly for five consecutive days. Learn more
