6 Products/Enduring Value Potential natural vegetation Existing vegetation using an improved classification Improved Ecological Systems interpretations for High Plains Abiotic Site Type Data Ground truth dataset (1,000+ Points in High Plains / 10,000+ Points Statewide) User will build their own added value: – Context (local, regional, statewide) – Management options – Conservation opportunity areas – Ecological significance and risk (riverine/aquatics as well) – Species habitat modeling – Development of educational and interpretive materials – Change detection

7 Field Data Collected includes: Top 3 dominant species in Tree, Shrub, Herbaceous and Succulent Strata Percent Woody and Herbaceous Cover Includes % Live Oak, Shrub, Tree, other Evergreen Landcover and Mapping System Reference photo

8 Current Extent of Texas Ecological Mapping System Data

9 Classify Land Cover (e.g. cold deciduous forest) Create Map with Named Mapping Units (e.g. West Gulf Coastal Plain Bottomland Seasonally Flooded Forest) Provide Interpretation of Mapping Units (booklet, summary statistics by ecoregion, etc.) Draft Mapping Targets (NatureServe Ecological Systems) 3-date TM Satellite Imagery (30m resolution) Training data from air photos plus ground data Environmental data (slope, aspect, elevation, solar insolation) Land use data (NRCS Common Land Units) Assign Information using soils, ecoregions, geology, ecological site type, hydrology (“modeling”) Design and Execute Presentation

43 Evolving and Improving Implementation Initially implemented in raster. Time consuming and prone to error introduction. Moved to vector, working with attributed polygons. Initial models used Excel. Moved to Access to reduce error introduction through transcription. Initial vector models used Model Builder. Moved to python to make implementation more transparent and reproducible. Improvements result in ability to rapidly iterate changes in model to visualization in map. Modeling issues can be quickly visualized and corrected.
