Description:
Abstract: A raster map of Apacherian-Chihuahuan Semi-Desert Grassland and Steppe distribution across the Madrean Archipelago Rapid Ecological Assessment (REA) boundary.
Purpose: The terrestrial ecosystems of the Madrean (MAR) Rapid Ecological Assessment (REA) is a coarse filter Conservation Element (CE) dataset. The terrestrial ecosystem dataset will be used as a input to the Landscape Condition Model. The Landscape Condition Model will be used to evaluate the relative ecological integrity of various conservation elements within the MAR REA.

Data Quality Information:
Attribute Value Accuracy Information:
Attribute Accuracy Report: This raster has two values: 1 = Apacherian-Chihuahuan Semi-Desert Grassland and Steppe presence of and 0 = absence.
Logical Consistency Report: The dataset is logically consistent. The dataset is a raster map that delineates the current distribution (presence = 1/absence = 0) of Apacherian-Chihuahuan Semi-Desert Grassland and Steppe within the Madrean Archipelago REA boundary.
Completeness Report: The Apacherian-Chihuahuan Semi-Desert Grassland and Steppe distribution map is complete within the Madrean Archipelago study area and is as complete/accurate as the three source datasets from which it was derived: TNC Grassland Assessment and MAR North American Warm Desert Lower Montane Riparian Woodland, Shrubland and Stream raster and MAR North American Warm Desert Riparian Woodland, Shrubland, Mesquite Bosque and Stream raster.
