This dataset covers the northern half of the Southern Rockies Landscape Conservation Cooperative. It was aggregated and converted to raster by Conservation Biology Institute as part of a soil vulnerability study funded in part by the Southern Rockies LCC. The soil data come from a digital soil survey, the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey...

Soil depth (cm) affects communities primarily because shallow soils (usually on steep slopes or ridgetops) limit deep-rooted plants. A "restrictive layer" is a nearly continuous layer that has one or more physical, chemical, or thermal properties that significantly impede the movement of water and air through the soil or that restrict roots or otherwise provide an unfavorable root environment. if no restrictive layer is described in a map unit, it is represented by the ">200' depth class, This attribute is actually recorded as three separate values in the database. A low value and a high value indicate the range of this attribute for the soil component. A "representative" value indicates the expected value of this...
This study explores the influence of variable soil depths on simulated land?atmosphere exchanges from a currently operational land surface model over the North American Monsoon (NAM) region of southwestern North America. It is shown that the neglect of observed (actual) soil depths can limit land surface model performance at the sites studied. The main impact of accounting for shallower soil depths is to increase the dispersion, (i.e. the dynamic range) of sensible and latent heat fluxes when compared with simulations using a common fixed soil column depth of 2 meters. It is also shown that accounting for local soil depth variability can, moderately, improve land surface model flux estimation as compared with tower...

This record contains scientific data characterizing soil properties and hydrologic response to rainfall associated with historic rainfall during September 2013 in the Colorado Front Range, USA. Data include soil depth, soil-hydraulic properties of field-saturated hydraulic conductivity and sorptivity, weathered bedrock hydraulic properties including field-saturated hydraulic conductivity and sorptivity, and soil saturation from automated sensors installed at various depths. Data sites include burned (fire-affected) and unburned (not affected by the 2010 wildfire).

The distribution and turnover of plant litter contribute to soil structure, the availability of plant nutrients, and regional budgets of greenhouse gasses. Traditionally, studies of decomposition have focused on the upper soil profile. Other work has shown that temperature, precipitation, and soil texture are important determinates of patterns of decomposition. Since these factors all vary through a soil profile, it has been suggested that decomposition rates may vary with depth in a soil profile. In this work, we examine patterns of root decomposition through a shortgrass steppe soil profile. We buried fresh root litter from Bouteloua gracilis plants in litterbags at 10, 40, 70, and 100 cm. Litterbags were retrieved...

Derived from 1:250,000-scale USGS HUC 8 boundaries, this dataset represents the soil thickness for the western USA. A weighted average was created for each HUC 8 watershed using approximate EMAP physical habitat substrate criteria. The values are expressed in inches to the depth the shallower: hardpan, rock layer or the maximum 60 inches.

Prairie dog (Cynomys spp.) populations have been reduced by 98% compared to historical levels because of widespread poisoning, habitat loss, recreational shooting, and outbreaks of sylvatic plague (Yersinia pestis). Our objectives were to identify habitat correlates of Gunnison's prairie dog (C. gunnisoni) colonies and to develop a predictive logistic regression model to identify potential reintroduction sites for this species. During 2000 and 2001, we examined habitat features at 50 Gunnison's prairie dog colonies and 50 paired random sites in northern Arizona, USA. When compared to random sites, Gunnison's prairie dog colonies had deeper soils, less variability in slope, and less rock ground cover. Our results...
