Soil family particle size class map for Colorado River Basin above Lake Mead

These data were compiled to support analysis of remote sensing data using the Disturbance Automated Reference Toolset (Nauman et al., 2017). The objective of our study was to assess results of pinyon and juniper land treatments. These data represent major soil types as defined primarily by soil texture and depth, but also geology, parent material, and geomorphology for relevant features that distinguish major ecological land units. These data were created from field soil descriptions collected in the upper Colorado River watershed mostly since 2000, but include some older data catalogued in USDS Natural Resources Conservation Service (NRCS) databases. These soils data used in model training were collected by NRCS...

Ecological Land Units

Conservation planning at any scale-regional, landscape level, or local-requires an understanding of patterns of environmental variation and biological diversity. Data on biological distributions of individual species are very often inadequate for a large-scale analysis of biodiversity. In the absence of suitable biological datasets, conservation science has recognized that physical diversity can be an acceptable surrogate for biological diversity. This recognition led to the development of the ecological land unit, or ELU. The ELU is a composite of several layers of abiotic information that critically influence the form, function, and distribution of ecosystems - elevation zone, bedrock geology, and landforms. Each...

Ecological Land Units

Conservation planning at any scale—regional, landscape level, or local—requires an understanding of patterns of environmental variation and biological diversity. This dataset was developed as a tool for assessing the biophysical character of landscapes, and for mapping the distribution and composition of community assemblages across those landscapes. Informed decisions on where to focus conservation efforts require such tools. Data on biological distributions are very often inadequate to a large-scale analysis of biodiversity. The close relationship of the physical environment to ecological process and biotic distributions underpins the ecological sciences, and in the absence of suitable biological datasets, conservation...
