In response to a drought State of Emergency declared by the Governor in January 2014 and subsequent executive orders, the California Department of Fish and Wildlife (CDFW) was charged to implement projects that respond to drought conditions through habitat restoration and other measures. To provide scientific information necessary to meet these conservation challenges, leadership at CDFW prioritized establishment of a statewide resource assessment program, one component of which would be to monitor wildlife populations and their vulnerability to drought stressors. The purpose of Terrestrial Species Stressor Monitoring (TSM) was to begin the monitoring process by collecting baseline survey data on a wide variety of common wildlife species throughout the Great Valley and Mojave Desert ecoregions. Data collected at some or all study sites include infrared camera trap images, ultrasonic acoustic recordings, audible acoustic recordings, visual encounter surveys for reptiles and amphibians, avian point counts, and vegetation surveys. The data will be used to estimate occupancy and abundance of wildlife species and to model associations with drought and other habitat conditions.
Time constrained surveys for reptiles and amphibians were conducted at 184 Great Valley study sites, and 107 Mojave Desert sites, between March and June 2017. Whenever possible, three independent surveys of 30 minutes each were conducted over the course of the month-long survey period at each site. Time constrained searches were typically conducted after completion of avian point count surveys. Once the study site lifeform was determined, the observer began their search within the stand, but could move throughout the lifeform. In narrow riparian areas, observers could search the edges of these habitats in addition to the main lifeform. Observers were free to move about anywhere within the lifeform, making sure to check any cover object that was safe to inspect; this included rock crevices, burrows, downed logs, etc. Moved cover objects were to be returned exactly as they were found. When an observation was made, observers recorded the species (six-letter code if known, otherwise full common or scientific names), time of observation, age class (hatchling, juvenile, adult) if possible, confidence level, and a GPS location. Each subsequent TCS was conducted with the same amount of intensity as previous searches.
