DATA RELEASE - Long-term Experimental Forest Growth and Drought Data

Forests around the world are experiencing severe droughts and elevated competitive intensity due to increased tree density. These data were compiled to represent multi-decadal forest growth across eight different experimental forests in the United States, each with replicated levels of density treatments, as well as an important drought index correlated to growth.

County Population 2100 Baseline Scenario Colorado Plateau

Future county population was based on projections for 2100 from the Spatially Explicit Regional Growth Model (SERGoM; Theobald 2005). SERGoM simulates population based on existing patterns of growth by census block, groundwater well and road density, and transportation distance to urban areas, while constraining the pattern of development to areas outside of protected areas and urban

Spatial distribution and risk analysis data for diamond-backed terrapins relative to crab trapping, Savannah Coastal Refuge Complex, USA

There were five objects for compiling these data: 1) to conduct a systematic inventory of diamond-backed terrapins (Malaclemys terrapin) using headcount surveys on four National Wildlife Refuges (Harris Neck, Blackbeard Island, Wassaw, and Wolf Island) that are a part of the greater Savannah Coastal Refuges Complex in southeast Georgia, USA; 2) to use occupancy modeling to

Geomorphic Change-Sediment Transport Data for the Little Colorado River, Arizona, USA

These data were compiled to accompany flow modeling work on Little Colorado river above the mouth (USGS gage 09402300). The data include topographic data collected by LIDAR and total station in June 2017, high water marks from nine historic floods, and control points and gage structures. Topographic data include ground topography collected by LIDAR and channel bathymetry collected by to

Legacy and lag effects data for the northern Colorado Plateau, USA

This climate and vegetation index dataset was collected from readily available open source data, such as Landsat. The data represents points across the northern Colorado plateau. The vegetation type was defined based on U.S. Geological Survey ReGAP data. Using compositing techniques by season we developed a dataset of lag and legacy for each point. We could then look to understand how both lag...

Simulated Soil Water Potential in National Parks and Monuments of the Southern Colorado Plateau, 1915-2099—Data

These data were simulated using the SOILWAT model and were intended to characterize soil-water conditions at different ecological sites on the Southern Colorado Plateau. SOILWAT is a daily, site-specific, multi soil-layer, ecosystem water-balance model, driven by daily meteorology, as well as site soil texture and vegetation. The sites simulated correspond with Inventory and Monitoring

Laboratory experiment data—turbidity response to increasing silt and clay concentration

These data were compiled during a laboratory experiment showing the turbidity response to increasing silt and clay concentration. The sediment used for the laboratory experiment was collected in the Grand Canyon study area, from the bank of the Little Colorado River, approximately 1 kilometer upstream from its confluence with the Colorado River. The sediment was passed through a 63 µm si

Projected Change in Aridity Index from 2016-2075 for the Colorado Plateau

Future annual aridity index (AI, precipitation divided by potential evapotranspiration [PET]) was calculated from monthly temperature and precipitation data extracted from 10 General Circulation Models from the Coupled-Model Intercomparison Project, Phase 5 (CMIP5) downscaled to 1/8° spatial resolution (Maurer et al. 2007, Bureau of Reclamation 2013). The models were

Central Mojave Desert Vegetation Mapping Project, California, 1997-1999: Special Features Points

The Central Mojave Special Features shapefile provides point locations for known or potential places where vegetation alliances or unique stands occurred (from 1997-1999) with less than 5 hectares of spatial extent. These designations were provided separately from the Mojave Vegetation Polygons because the target standard for the polygons was a minimum mapping unit (MMU) of 5 hectares,

Hatchery Trout Predation Data, Arizona

These data were compiled to evaluate the potential adverse impacts that stocked trout may have on native fish populaitons through predation. Hatchery-reared rainbow and brown trout are typically fed exclusively on commercially prepared pelleted feeds and have no experience catching or consuming life fish at the time of stocking and yet stocked fish are percieved to present a high predation...

Geomorphic Change-Sediment Transport Data for Kanab Creek, Arizona USA

These data were compiled to accompany flow modeling work on Kanab Creek near the mouth (USGS gage 09403850). The data include topographic data collected by a remote sensing detection light detection and ranging (LIDAR) system and surveying total station in June 2017, high water marks from six floods from 2011 to 2013, and control points and gage structures. Topographic data include gr

Forest Service Visits 2014 Colorado Plateau

We calculated the intensity of recreation visitation in 2014 based on Forest Service (FS) visits reported in the National Visitor Use Monitoring System at the level of a National Forest (English et. al., 2002). Recreation use on FS lands is tracked at five-year intervals (2010–2014), therefore these data represent a rough estimate of potential 2014 visits. English, D.
