The ECOFOC_GEO10 layer represents Terrestrial Conservatioin Focus Areas that are greater than or equal to 10 hectares in size. Conservation Focus Areas are threatened areas of ecological importance. They range from 0 (no risk, no importance) to 3 (high risk, high importance). They were derived from a series of data sets, including agriculture, development and toxic threats, a measure of ecological significance and an analysis of irreplaceability for a set of conservation targets. Full details of the procedure can be found in Diamond, Sowa and Foster, 2005, "Development of Conservation Focus Area Models for EPA Region 7".

This is an aggregate national dataset describing the geographic boundaries of the ACEC within the BLM managed public lands. The designated ACECs are "areas within the public lands where special management attention is required to protect and prevent irreparable damage to important historic, cultural, or scenic values, fish and wildlife resources or other natural systems of processes, or to protect life and safety from natural hazards."

SIG_REGIONS is a boundary layer that displays Region 7's Significant Ecological Resource Areas. This layer represents large areas within which different ecosystem types occur, such as the Prairie Pothole wetland depressions in northern Iowa or the Flint Hills tall grasslands in eastern Kansas. Note: a particular ecosystem type may not be contiguous throughout an entire polygon; rather, that ecosystem type can be found there.

This dataset contains information regarding the acreages of land currently (as of 2004) enrolled in the Conservation Reserve Program (CRP) distributed by county and the year the CRP contract was initiated (1987-2004, excluding 1994 and 1995). Additionally, it contains total acreages of land enrolled in the CRP distributed by county and the contract year (1987-2003). USDA Farm Service Agency's (FSA) Conservation Reserve Program (CRP) is a voluntary program available to agricultural producers to help them safeguard environmentally sensitive land. Producers enrolled in CRP plant long-term, resource-conserving covers to improve the quality of water, control soil erosion, and enhance wildlife habitat. In return, FSA provides participants with rental payments and cost-share assistance. Contract duration is between 10 and 15 years. Acreage enrolled in the CRP is planted to resource-conserving vegetative covers, making the program a major contributor to increased wildlife populations in many parts of the country. These spatial data were created by cross-referencing a base map of counties in the western U.S. with tabular data provided by: (1) Data in the columns labeled by year indicate the "Total All Practices" acreage entered into active CRP contracts in that county in that year. (2) Information requested under the Freedom of Information Act (USDA Case#2004-180) Although the CRP Program continues, and new lands are entered into contracts and some contracted lands expire, this map is static as of the publication date because it was created for a specific analysis. A user could update this dataset by editing the attribute table with new data as it is produced.

The Percentage Potential Wetland Area on Cultivated Cropland (PWAC) layer shows areas where conditions may be suitable for wetland restoration or creation at a 10-m resolution. Since the 1600's, an estimated 53% of wetlands in the Conterminous United States have been lost, with many areas being converted for agricultural or urban use. The ecosystems services provided by wetlands are extremely valuable, providing flood attenuation, water filtration, nutrient sequestration, vital habitat, and many others. Wetland restoration or creation can help restore these benefits for the surrounding community. There are several government and community projects that can utilize these data to assist in site selection for wetland restoration projects. This layer was created using the Random Forest (RF) machine learning algorithm in Google Earth Engine (GEE). The RF model utilized 17 data inputs to identify areas where attributes on the landscape are similar to the attributes found in existing wetlands. The input data for this layer fall into three categories: topographic variables, soils, and satellite imagery. Topographic - DEM's sourced from USGS 3D Elevation Program (10-m) -Elevation -Aspect -Slope -Compound Topographic Index (CTI) -Vertical Overland Flow Distance (VOFD) -Horizontal Overland Flow Distance (HOFD) -Pythagoras Overland Flow Distance (POFD) -Soils - Natural Resource Conservation Service's gNATSGO and gSSURGO products · Potential Wetland Soils (PWS) -European Space Agency's Sentinel-1 Synthetic Aperture Radar (10-m) Using these variables, the Random Forest model was run for each 2 digit Hydrologic Unit Code (HUC) in Google Earth Engine. The model used wetlands from the National Wetland Inventory (NWI) to create training data, masking out deep water areas such as the centers of lakes and rivers, and excluding estuarine and marine wetlands. For each HUC an equal number of wetland an non-wetland training points proportional to the size of the HUC were generated, with 30% of those points being reserved for accuracy assessment. The model results were then intersected with NLCD's land cover class Cultivated Cropland. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).
