Getting started with the Texas A&M Natural Resources Institute TxMAP tool
O v e r v i e w
TxMAP provides Texas stakeholders with information to better understand and visualize natural resources across the state through the detailed
curation
of
multiple
statewide
datasets that represent our program areas of Wildlife Conservation and Mitigation, Land Trends
and
Demography,
Military
Land
Sustainability, and Private Land Stewardship. The tool allows users to customize the interactive map by defining areas of interest to perform an intersect query on selected geospatial data layers. Results can be printed directly, or exported as an informative report.

Here, users will be prompted to customize their search area through a simple step-by-step process directed on the lefthand side of the page. Results can be exported using the Create Report function at Step 5, or a simple map can be printed by selecting the Print Map button. While exploring the web tool, users can also utilize various stationary features, listed here.

Users must select the Report function for at least one data layer in order to export a report. Some data layers may not appear to draw on the map because they are county-level datasets (such as the Private Land Stewardship layers). Clicking on the map will provide "pop-up" information about visible data layers. Select the left and right arrows on the pop-up window to view multiple records. Drawing times may vary depending on the map extent and detail of the layer. Report and/or Map data layers: Report and/or map all data layers within a group by checking the Report and/or Map box next to the group name. Report and/or map individual data layers by checking the Report and/or Map box next to the layer name. 5

Data source: United States Census Bureau Elevation - Statewide elevation contours at 5 foot intervals. Data source: United States Geological Survey (USGS) Ecoregions – Gould's ecological regions of Texas. Data source: Texas Parks and Wildlife Department (TPWD) Air Quality PM10 - Estimated airborne particulate matter particles, less than 10 microns in size (PM10), in soil surface. Designed to identify areas that could emit PM10 particles and to describe the possibility on a scale of 0 (no or very low risk) to 1.00 (highest risk). Data source: SSURGO database from the Natural Resources Conservation Service (NRCS) Air Quality PM2.5 - Estimated airborne particulate matter particles, less than 2.5 microns in size (PM2.5), in soil surface. Designed to identify areas that could emit PM2.5 particles and to describe the possibility on a scale of 0 (no or very low risk) to 1.00 (highest risk). Data source: SSURGO database from the Natural Resources Conservation Service (NRCS) Mechanical Site Prep - Estimated suitability values for use of surface-altering soil tillage equipment during site preparation in forested areas. "Well suited" indicates the soil has features that are favorable for the specified kind of site preparation and has no limitations. "Poorly suited" indicates the soil has one or more properties that are unfavorable for the specified kind of site preparation.
Mechanical Site Prep cont. - "Unsuited" indicates the expected performance of the soil is unacceptable for the specified kind of site preparation or extreme measures are needed to overcome the undesirable soil properties. Data source: SSURGO database from the Natural Resources Conservation Service (NRCS) Pond/Reservoir Areas - Estimated suitability values for pond reservoir construction. Soil best suited to this use have low seepage potential in the upper 60 inches. The seepage potential is determined by the saturated hydraulic conductivity (Ksat) of the soil and the depth to fractured bedrock or other permeable material. Excessive slope can affect the storage capacity of the reservoir area. "Not limited" indicates the soil has features that are very favorable for the specified use. Good performance and very low maintenance can be expected. "Somewhat limited" indicates the soil has features that are moderately favorable for the specified use. The limitations can be overcome or minimized by special planning, design, or installation and fair performance and moderate maintenance can be expected. "Very limited" indicates the soil has one or more features that are unfavorable for the specified use. The limitations generally cannot be overcome without major soil reclamation, special design, or expensive installation procedures. Poor performance and high maintenance can be expected. Data source: SSURGO database from the Natural Resources Conservation Service (NRCS) Prescribed Burning - Estimated suitability values for prescribed burning. Ratings represent the relative limitations of soil and physiographic factors upon the ability to safely contain the fire, as well as soil and climatic factors on the ability to obtain a favorable vegetative response to the treatment. Additionally, this value assesses 7

Prescribed Burning cont. - the risk of water and wind erosion prior to reestablishing adequate watershed cover on the treatment site. Soils that are rated "not limited" have no restrictions for prescribed burning. A "somewhat limited" rating implies that the soil has features that may impede prescribed burning. A "very limited" rating indicates that the soil characteristics are such that they limit or prohibit prescribed burning. Data source: SSURGO database from the Natural Resources Conservation Service (NRCS) Range Production - Estimated range production values. Total range production is the amount of vegetation that can be expected to grow annually in a well managed area that is supporting the potential natural plant community. It includes all vegetation, whether or not it is palatable to grazing animals. Values are expressed in pounds per acre of air-dry vegetation in a normal year (growing conditions are about average). Data source: SSURGO database from the Natural Resources Conservation Service (NRCS) Soil Erosion - Estimated susceptibility values for soil erosion (factor K). Erosion factor K indicates the susceptibility of a soil to sheet and rill erosion by water. Values of K range from 0.02 to 0.69. Other factors being equal, the higher the value, the more susceptible the soil is to sheet and rill erosion by water. Data source: SSURGO database from the Natural Resources Conservation Service (NRCS) Upland Native Herbaceous Plants - Estimated suitability as either primary or secondary wildlife habitat through the establishment and maintenance of native herbaceous plants. The ratings are for the soils in their natural condition and do not consider present land use, existing vegetation, water sources, and the presence or absence of wildlife in the area. The soil properties and qualities
Upland Native Herbaceous Plants cont. - important in the establishment and management of upland native herbaceous plants are soil temperature, available water holding capacity, wetness, coarse fragments in the surface, salts, moisture regime, surface clay or sand content. Rating class terms indicate the extent to which the soils are limited by the soil features: "not limited" indicates the soil has no limiting features, "somewhat limited" indicates the soil has limiting features that can be overcome with proper planning, design, installation, and management, "very limited" indicates that the soil has one or more very limited features that can only be overcome with special planning, major soil modification, special design, or significant management practices. Data source: SSURGO database from the Natural Resources Conservation Service (NRCS) Wildlife Food Plots - Estimated soil suitability for planting and cultivating food plots to produce forage for upland wildlife species. The soil properties that affect establishment of wildlife food plots are surface texture, pH, salinity, sodium, soil drainage, flooding, ponding, depth to water table, organic matter content, slope, and surface gravels, cobbles, and stones. "Not limited" indicates the soil has no limiting features, "somewhat limited" indicates the soil has limiting features for the specified use that can be overcome with proper planning, design, installation, and management, "very limited" indicates the soil has one or more very limiting features that can only be overcome with special planning, major soil modification, special design, or significant management practices.
