Soil data were obtained from the SSURGO
database (Soil Survey Staff 2016).
Environmental covariates of the vegetation shift.--We spatially overlaid soil survey (SSURGO
), elevation, and climate (PRISM) values to the PLS trees mapped in ArcGIS.
The Soil Survey Geographic (SSURGO
) and State Soil Geographic (STATSGO) soils data of the National Resource Conservation Service have been used in GIS analyses to reconstruct historical presettlement vegetative cover (Stetler et al.
For the below-ground components of New Jersey forests, we relied primarily on USDA Natural Resources Conservation Service (NRCS) Soil Survey Geographic (SSURGO
For example, in the United States, two orders of soil maps, State Soil Geographic (STATSGO) and Soil Survey Geographic (SSURGO
) databases, have been developed and they provide spatial distribution of pcdological properties for different purposes (Soil Survey Division Staff 1993).
The objective of this study was to combine Soil Survey Geographic Database (SSURGO
) data with field data to determine correlations between soil phosphorus and soil properties such as clay percentages, slope, and permeability.
The United States Department of Agriculture soil databases SSURGO
, STATSGO, and NATSGO are examples of national databases at different resolutions (Lytle 1993), and the World Soils and Terrain Digital Database (SOTER) is an international one (Oldeman and Van Engelen 1993).
The Bureau of Land Management is using the Soil Survey Geographics database (SSURGO
) with the geographic information system (GIS) to create native vegetation maps for eastern Idaho.

The most detailed resource is the Soil Survey Geographic Database (SSURGO

Soil characteristics for the remaining sites are obtained from the National Cooperative Soil Survey (NRCS) Soil Survey Geographic Database (SSURGO
