The Regional Ecological Assessment Protocol (REAP) is a screening level tool created as a way to identify priority ecological resources within the five EPA Region 6 states (Arkansas, Louisiana, New Mexico, Oklahoma, and Texas). The REAP divides eighteen individual measures into three main sub-layers: diversity, rarity, and sustainability. This geodatabase contains the diversity layers. There are 2 diversity grids within this geodatabase (diversity & diversityrank). The diversity layer shows land cover continuity and diversity. There are three measures that make up the diversity layer: appropriateness of land cover, contiguous size of undeveloped area, and the Shannon land cover diversity index. Each cell in the final diversity grid has a score of between 1 and 100 based on the average of the three measures. Cells with higher scores represent areas that are more diverse. Cells with lower scores represent areas that are the least diverse. In the diversityrank grid, the cells are placed into the following 5 groups based on the score: 1 (top 1% of scores), 10 (top 10% of scores), 25 (top 25% of scores), 50 (top 50% of scores), and 100 (all the rest of the scores). See each individual feature class for more detailed metadata.
