These data (all data tables for the data release) represent a suite of biotic and abiotic variables that characterized plant communities and the geologic, geomorphic, edaphic, climatic, and land use history context in which distinct plant communities occur. In 2009, the National Park Service's Inventory and Monitoring program for the Northern Colorado Plateau Network (NCPN) began measuring vegetation cover and site characteristics at monitoring plots stratified across different vegetation types within national parks on the Colorado Plateau. NCPN biologists remeasured vegetation cover at these plots in a rotating panel over the following decade. In 2019, U. S. Geological Survey geologists and soil scientists collected/compiled...
This database contains demographic and movement variables for 158 adult Agassiz's desert tortoises (Gopherus agassizii) translocated from the National Training Center (NTC), Fort Irwin, in the central Mojave Desert, California, in spring of 2008 and monitored through fall of 2018. The tortoises, fitted with radio transmitters, were translocated to plots south of Fort Irwin and followed monthly until fall of 2018, when transmittered were removed, and the project was ended. The database consists of unique identification numbers of the tortoises, sex and size, dates, details of locations, and status of the tortoises. These data support the following publication: Mack, J.S. and Berry, K.H., 2023. Drivers of survival...

The Shasta salamander (Hydromantes shastae) has been petitioned for listing under the Endangered Species Act. The greatest threat to the species is likely habitat loss that will be caused by the increase in elevation of Shasta Lake that will occur with proposed increases in the height of Shasta Dam to increase water storage capacity and maintain cold water for Chinook salmon (Oncorhynchus tshawytscha). Another potential threat is the fungus Batrachochytrium salamandrivorans, which has not yet been detected in North America but is lethal to related salamanders (Hydromantes strinatii) in Europe (Martel et al. 2014). In addition to these threats, recent genetic evidence suggests that the species as originally petitioned...
These data consist of environmental covariates and estimated plot-level mortality of ponderosa pine trees. Environmental covariates include growing season temperature and soil moisture, and values are summarized into long-term mean conditions, and anomalies observed between forest inventory sampling events for each plot. Data also include plot locations (with uncertainty introduced by the US Forest Service to maintain private property rights), plot basal area, and several variables related to estimated mortality rate of ponderosa pine trees under various assumptions about basal area conditions.

The purpose of this field data collection was to test and compare the OceanInsight HDX Mini Spectrometer as an accessible alternative against the more expensive ASD Fieldspec for collecting ground-based hyperspectral reflectance profiles for landcover analysis. The data collection took place in Dog Head Marsh and South Cape Beach within the Waquoit Bay National Estuarine Research Reserve (WBNERR). The hyperspectral profiles were collected side-by-side with both field-spectrometers using comparable sensor collection settings for various ground cover samples. The terrain and vegetation type of these sample were described as well as surveyed using Real Time Kinematic Global Positioning System (RTK-GPS). This data...

This data release presents data used for analyzing spatial and temporal differences in soil surface roughness within selected biocrust communities. These records were collected by ground-based lidar for 121, 1m x 3m soil plots with biological soil crusts (biocrusts). Roughness was estimated from 5 mm resolution data (CloudCompare v. 2.10.2, 2019) for two Great Basin Desert sites (UTTR-1; UTTR-2) in December 2015 and one Chihuahuan Desert site (JER) in February 2016. Data were again collected in June 2018 for UTTR-1 and UTTR-2. Additional field and laboratory data were included within this study to understand differences in soil surface roughness between UTTR and JER as well as between the 2016 and 2018 surveys at...
These data were compiled to assess the response of vegetation and biological soil crusts to drought in a semi-arid ecosystem on the Colorado Plateau near Moab, Utah. Objective(s) of our study were to explore how vegetation cover, soil conditions, and growing season nitrogen (N) availability are impacted by multifaceted drying climate conditions using data from a long-term precipitation reduction experiment (30% reduction). In 2010, U.S. Geological Survey biologists installed paired experimental plots with a control plot and a plot covered by a shelter that excluded 35% of incoming precipitation. These 40 sites represent shallow vs. deep soils and sandstone vs. shale parent material. These data were collected at...
These data were compiled to measure airborne horizontal mass flux of sediments moved by wind across soils, climates, vegetation types, and land uses on the Colorado Plateau. Objectives of our study were to quantify spatial and temporal patterns in wind erosion and further our understanding of how soil and site setting, climate, and land uses are controlling wind erosion and horizontal mass flux. These data represent seasonal cumulative horizontal mass flux as measured using passive aspirated sediment traps, Big Spring Number Eight (BSNE) samplers. These data were collected in Grand and San Juan counties, Utah, and Mesa County, Colorado, USA between August 2017 and November 2020. These data were collected by the...
A green-tree reservoir (GTR) is a stand of bottomland hardwoods that is intentionally flooded in the fall and winter to support migrating waterfowl. Bottomland hardwood forest plots in the GTR on Felsenthal National Wildlife Refuge (FNWR) are measured every 5-6 years to monitor tree survival, growth, and mortality. This dataset presents the measurements of all the trees in 54 plots during the year 1995. Parameters measured are species, diameter, vigor class, canopy class, and whether or not the tree is a new recruit in 1995. These parameters are defined in the Entity and Attributes section of this metadata file. Additional Information: A series of square 0.1 ha (31.6 m X 31.6 m) permanent plots was previously established...

We used a stratified-random sampling approach to estimate the total abundance of Wedge-tailed Shearwater (Ardenna pacifica) nest sites across Kīlauea Point National Wildlife Refuge (KPNWR), Kauaʻi, in 2019. To estimate stratum-specific nest site abundance, we generated randomly located, non-overlapping circular plots within several sampling strata. We set plot radius to 5 m in most strata, except for some portions of Kīlauea Point where a 3-m radius was used to accommodate narrow strips of habitat. We generated enough plots to survey 10 percent of total stratum area where we expected high nest site abundance, and 5 percent of stratum area where expected nest site abundance was low or minimal. This data table contains...
