Phase I of the Arkansas SRA represents a snapshot in time of the estimated acres of land considered to be potentially at-risk for resource degradation with regard to the 29 natural resource concerns addressable by NRCS programs within Arkansas. These areas have been identified because of their possibility of existing or future degradation due to natural or anthropogenic phenomena. The results of the phase I SRA inventory will help guide conservation planners and managers. The models will be refined and will continue to be enhanced as new data, information and processes are identified. The process of modeling these at-risk areas within Arkansas was dependent upon the existing digital geospatial datasets, NRCS staff expertise and involvement of the Conservation Partners and community. The phase I project team agreed that additional information and refinement input GIS datasets will likely help refine the understanding and delineation of the areas with the greatest need for conservation programs. The input from the local scientific and natural resource conservation experts within Arkansas were invaluable to the GIS model development during this project phase; it is their input and experience that will improve upon these phase I GIS models and provide a more comprehensive understanding of the extent of resource concern within the state.
The full collection of input data layer maps and larger versions of the resulting model output maps are located online at the Resource Assessment of Arkansas website. Complete GIS datasets and metadata for each of the model input layers and resulting raster datasets are also available for download and are compatible with ESRI ArcGIS 10 products.
