SIR 2014-5076, Land-Cover Data for Red Rock Canyon National Conservation Area and Coyote Springs, Piute-Eldorado Valley, and Mormon Mesa Areas of Critical Environmental Concern, Clark County, Nevada

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Four polygon vector data sets and one related table describe land-cover in Red Rock Canyon National Conservation Area (RRC_NCA_p) and Coyote Springs (CS_ACEC_p), Piute-Eldorado Valley (PEV_ACEC_p), and Mormon Mesa (MM_ACEC_p) Areas of Critical Environmental Concern, Clark County, Nevada. One polygon vector data set per Area is attributed with land- cover at the vegetation stand level (abbreviated with a stand code) and the corresponding...

Mojave Desert Tortoise (Gopherus agassizii) Morphometrics and Egg Data from Seven Sites across the Mojave, (1997-2002)

These data were acquired from 7 study sites distributed across the range of Gopherus agassizii. Data were collected from 1997 to 2002 as part of three separate studies, although data were not collected at all sites in each year. Radio-transmitters were attached to the carapace of 151 females and VHF radio-telemetry was used to relocate animals to assess reproductive status. Egg production was determined from X-radiographs taken weekly/biweekly intervals (depending on the study) using a portable X-ray machine between April and July or August of each year. In addition, the mean carapace length (MCL) of each tortoise was measured at each time of capture or recapture using calipers (mm). A nesting event was recorded...
