The GCPO LCC assessed landscapes within the broad vegetative class of grasslands at a spatial resolution of 30 meters using a national database of existing vegetation type (LANDFIRE) combined with various high resolution data layers obtained from the states of Oklahoma, Texas, and Florida, and from researchers, non-governmental agencies, and state agencies for Alabama, Arkansas, Mississippi, and Missouri. This process identified over 32 million acres of the grassland vegetative type (broadly defined) and just over 1 million acres meeting the more restrictive definition of prairie (Figure 1). However, none of those areas identified as prairie were shown to meet all four of the condition endpoints assessed, and only...
This layer was created by selecting classes relevant to conservation of the grassland-prairie-savanna broadly defined habitat from the LANDFIRE Existing Vegetation Type (evt) spatial data product clipped to the boundary of the GCPO LCC. The layer was generated as in input layer for the Draft Grassland Condition Index raster data layer in support of the GCPO LCC rapid ecological assessment of the Grassland-Prairie-Savanna Priority Habitat. In selecting vegetation types, “grasslands” were defined as any landscape dominated by grass, excluding classes considered to be features of other priority habitats, such as marshes, dunes, glades, woodlands, and pine savanna. The 44 selected grassland classes included pasture/hay...

The grassland condition index raster data layer assigns to each 30 meter pixel in the GCPO a condition index score generated by the presence or absence of a set of desired conditions such as patch size, vegetation height, etc. This grassland bar code layer indicates which conditions contributed to the index value score, and by how much, by use of a nine-digit code. The digits in the code represent the following input conditions in order: potential for restoration, presence of a grassland ecological system, presence of prairie (a subset of grasslands characterized by the presence or dominance of native vegetation), configuration in a patch > 100 acres, and the four site-level condition endpoints: vegetation height...

The amount, configuration, and condition of grasslands, prairies, and savannas in the Gulf Coastal Plains and Ozarks Landscape Conservation Cooperative (GCPO LCC) was assessed at 30 meter spatial resolution. Each pixel was assigned a score based on a dichotomous decision tree evaluating the following: whether described as a grassland ecological system class, if not, whether potentially restorable to grassland, if grassland, whether dominated by native plants (prairie), whether in a patch >100 acres in size, and whether described as having any of four condition endpoints: vegetation height (> 1 meter), vegetation cover (> 80% herbaceous or < 20% shrub), tree density (< 10 trees per acre), and disturbance pattern...
