State: California

Coordinate: 34° 53' N, 115° 43' W
Basis of coordinate: based on nearby landmark
Geography comments: "Our study area was in the southern portion of the Mojave Desert ecoregion of California"
Coordinates based on the Mojave National Preserve, located in the study area
"Elevations range from 1472, 414 m"
Climate and habitat
Habitat: desert/xeric shrubland
Protection: other protected area
Substrate: ground surface
Disturbance: grazing
Habitat comments: "Rainfall is limited, with just 020 mm of precipitation per month"
"The dominant plant species is creosote scrub, but the area encompasses a mosaic of vegetation types including saltbrush, Joshua trees, single-leaf pinyon, and mesquite"
"Most of the land is designated as federally protected, or as recreation management areas"
"Federally protected land is used primarily for recreational purposes, with limited livestock grazing"
Life forms: bats, carnivores, ungulates, other small mammals, birds
Sampling methods: baited, automatic cameras, call recordings
Sample size: 5760
Years: 2016, 2017
Nets or traps: 200
Net or trap nights: 6365
Camera type: digital
Cameras paired: no
Sampling comments: "We surveyed 200 sites between March and July of 20162017"
"We identified survey locations by first selecting a spatially balanced random sample of hexagons ... (hexagon radius is ∼2.6 km)"
"We then randomly selected 13 survey locations within each hexagon, which were spaced by 12 km and stratified by vegetation community"
"At each survey location, we concurrently deployed a PC900 camera trap (Reconyx, Holmen, WI, USA) and a SM3-BAT bioacoustic recorder with microphone (Wildlife Acoustics, Inc., Maynard, MA, USA)"
"We cable-locked cameras and acoustic recorders to securely placed T-posts 1 m and 2 m above the ground, respectively; T-posts were separated by ≥30 m"
"We deployed cameras for an average of 34   7.6 (SD) days and baited them during their initial deployment with a 250-g salt lick, 100 mL of rolled oat-peanut butter mixture, and 150 g of fish cat food"
"We programmed cameras to take 3 photos at each trigger event, with a delay of 1 second between trigger events"
For bird identification: "We programmed acoustic recorders to record 3 5-minute sessions on 3 consecutive days during the survey period"
"The first session was at 30 minutes before sunrise, the second at sunrise, and the third at 30 minutes after sunrise" (for a total of 1794 recordings)
For bat identification: "We also programmed the acoustic recorders to record full spectrum (i.e., 6192 kHz) ultrasonic triggers from 30 minutes before sunset until 0400 the following morning for 8 consecutive days on average (range = 310 days)" (for a total of 1574 acoustic recorder nights)
"We used Kaleidoscope Pro version 4.3.2 with the KPro classifier (Wildlife Acoustics, Maynard, MA, USA) to auto-classify file recordings to the bat species level" (which were then manually reviewed)
