Habitat: Mediterranean woodland

Altered habitat: fragment

Substrate: ground surface

Habitat comments: "The park is 951 ha, comprised primarily of coastal sage scrub and chaparral vegetation communities with some riparian and native and non-native grassland habitats.

Sampling comments: "We established a total of seven sampling points on official and unofficial trails within the park in January 2017... we installed one motion-triggered camera (Bushnell TrophyCam HD Aggressor) at each sampling point"
sampling was from November to February 2017 - 208 and April to May 2018
trap-days per camera are reported and total 596, but "we randomly subsampled 20% of photos between 11 am and 5 pm at all sampling points" (meaning that 75% of all hours were sample completely and 25% were sample at a rate of 20%, summing to 80% x 596 = 476 trap-days)
dogs, horses, and people were also photographed, but exact counts are not given
