Supporting energy and mineral development through successful reclamation
Federal lands of the US contain important reserves of oil, gas and other resources important for Unleashing American Energy (SO 3418). After development of these resources is complete, successfully reclaiming disturbed lands is a necessary step towards restoring wildlife habitat, forage production, and maintaining natural resources for future use. To improve reclamation outcomes on these lands and...
USGS Southwest Repeat Photography Collection: Kanab Creek, southern UT and northern AZ, 1872-2010 USGS Southwest Repeat Photography Collection: Kanab Creek, southern UT and northern AZ, 1872-2010
The USGS Southwest Repeat Photography Collection (Collection), formerly named the Desert Laboratory Repeat Photography Collection, is now housed by the Southwest Biological Science Center (SBSC) in Flagstaff, Arizona. It contains images from the late 1800s to mid-2000s, and was assembled over decades by now retired USGS scientists Drs. Robert H. Webb and Raymond M. Turner. There are 80...
Variable Terrestrial GPS Telemetry Detection Rates: Parts 1 - 7Data Variable Terrestrial GPS Telemetry Detection Rates: Parts 1 - 7Data
These data were used to explore environmental effects on fix success rates (FSR) across a wide range of environmental conditions, desert to alpine biomes, and cover the full range of potential data loss (0-100% FSR) for global positioning system (GPS) bias correction of terrestrial GPS-derived, large mammal habitat use. Also, these data were subsequently used to evaluate patterns in...

High female desert tortoise mortality in the western Sonoran Desert during California’s epic 2012–2016 drought High female desert tortoise mortality in the western Sonoran Desert during California’s epic 2012–2016 drought
We conducted population surveys for desert tortoises Gopherus agassizii at 2 nearby sites in the western Sonoran Desert of California, USA, from 2015-2018, during the driest ongoing 22 yr period (2000-2021) in the southwestern USA in over 1200 yr. We hypothesized that drought-induced mortality would be female-biased due to water and energy losses attributable to egg production during...

Birds not in flight: Using camera traps to observe ground use of birds at a wind-energy facility Birds not in flight: Using camera traps to observe ground use of birds at a wind-energy facility
Context: Camera trapping is increasingly used to collect information on wildlife occurrence and behaviour remotely. Not only does the technique provide insights into habitat use by species of interest, it also gathers information on non-target species.Aims: We implemented ground-based camera trapping to investigate the behaviours of ground-dwelling birds, a technique that has largely...

Micro-geographic variation in burrow use of Agassiz’s desert tortoises in the Sonoran Desert of California Micro-geographic variation in burrow use of Agassiz’s desert tortoises in the Sonoran Desert of California
Little has been published regarding the burrowing habits of Agassiz’s desert tortoises (Gopherus agassizii) in the Sonoran Desert of California. We monitored the interactions of tortoises with their burrows, and other tortoises, via radio-telemetry at two nearby sites between the Cottonwood and Orocopia Mountains, from 2015-2018. We examined how annual cycles of drought and non-drought...

Agassiz’s desert tortoise (Gopherus agassizii) activity areas are little changed after wind turbine-induced fires in California Agassiz’s desert tortoise (Gopherus agassizii) activity areas are little changed after wind turbine-induced fires in California
Wind turbine-induced fires at a wind energy facility in California, USA, provided an opportunity to study the before and after effects of fire on a population of protected Agassiz’s desert tortoises (Gopherus agassizii) in the Sonoran Desert, a species and ecosystem poorly adapted to fire. We compared annual activity areas (AAs) of tortoises in 2011 and 2013, before and after two 2012...

Geomorphometry in landscape ecology: Issues of scale, physiography, and application Geomorphometry in landscape ecology: Issues of scale, physiography, and application
Topographic measures are frequently used in a variety of landscape ecology applications, in their simplest form as elevation, slope, and aspect, but increasingly more complex measures are being employed. We explore terrain metric similarity with changes in scale, both grain and extent, and examine how selecting the best measures is sensitive to changes in application. There are three...

Landscape-scale wildlife species richness metrics to inform wind and solar energy facility siting: An Arizona case study Landscape-scale wildlife species richness metrics to inform wind and solar energy facility siting: An Arizona case study
The juxtaposition of wildlife and wind or solar energy facility infrastructure can present problems for developers, planners, policy makers, and management agencies. Guidance on siting of these renewable energy facilities may help identify potential wildlife-facility conflicts with species of regulatory or economic concern. However, existing spatial guidance usually does not consider all...

Reproductive output and clutch phenology of female Agassiz's desert tortoises (Gopherus agassizii) in the Sonoran Desert region of Joshua Tree National Park Reproductive output and clutch phenology of female Agassiz's desert tortoises (Gopherus agassizii) in the Sonoran Desert region of Joshua Tree National Park
Agassiz's desert tortoise (Gopherus agassizii) reaches the southern edge of its range in the Sonoran Desert of California. The reproductive ecology of this wideranging species is understudied here compared to populations in the adjacent Mojave Desert. Understanding potential geographic variation in reproductive ecology is important for effective management of conservation-reliant species...

Quantifying animal movement for caching foragers: the path identification index (PII) and cougars, Puma concolor Quantifying animal movement for caching foragers: the path identification index (PII) and cougars, Puma concolor
Relocation studies of animal movement have focused on directed versus area restricted movement, which rely on correlations between step-length and turn angles, along with a degree of stationarity through time to define behavioral states. Although these approaches may work well for grazing foraging strategies in a patchy landscape, species that do not spend a significant amount of time...

Mammalian mesocarnivore visitation at tortoise burrows in a wind farm Mammalian mesocarnivore visitation at tortoise burrows in a wind farm
There is little information on predator–prey interactions in wind energy landscapes in North America, especially among terrestrial vertebrates. Here, we evaluated how proximity to roads and wind turbines affect mesocarnivore visitation with desert tortoises (Gopherus agassizii) and their burrows in a wind energy landscape. In 2013, we placed motion-sensor cameras facing the entrances of...

Is GPS telemetry location error screening beneficial? Is GPS telemetry location error screening beneficial?
The accuracy of global positioning system (GPS) locations obtained from study animals tagged with GPS monitoring devices has been a concern as to the degree it influences assessments of movement patterns, space use, and resource selection estimates. Many methods have been proposed for screening data to retain the most accurate positions for analysis, based on dilution of precision (DOP)...

Variable terrestrial GPS telemetry detection rates: Addressing the probability of successful acquisitions Variable terrestrial GPS telemetry detection rates: Addressing the probability of successful acquisitions
Studies using global positioning system (GPS) telemetry rarely result in 100% fix success rates (FSR), which may bias datasets because data loss is systematic rather than a random process. Previous spatially explicit models developed to correct for sampling bias have been limited to small study areas, a small range of data loss, or were study-area specific. We modeled environmental...

A potential predator-prey interaction of an American badger and an Agassiz's desert tortoise with a review of badger predation on turtles A potential predator-prey interaction of an American badger and an Agassiz's desert tortoise with a review of badger predation on turtles
The federally threatened Agassiz’s desert tortoise (Gopherus agassizii) was listed under the U.S. Endangered Species Act in 1990, but thus far, recovery efforts have been unsuccessful (U.S. Fish and Wildlife Service [USFWS] 2015). Predation has been identified as a contributing factor to declining G. agassizii populations range-wide (e.g., Esque et al. 2010, Lovich et al. 2014)...
