2010 Landsat TM satellite imagery was analyzed to develop the KIRA predicted relative abundance model. Three parameters were used in the model : (1) mean open water (MOW) at a 180 m scale, (2) mean spring normalized difference vegetation index (NVDI) at a 180 m scale, and (3) coefficient of variation (CV) of spring modified normailized difference water index (MNDWI) at a 1 km scale. Model output was divided into 5 quantiles for display purposes and to aid interpretation. King Rail inhabit marshes in the fresh-to-intermediate salinity range. Using the KIRA predicted relative abundance modeled parameters, the GCJV identified areas of brackish marsh that exhibited high quality vegetative structure within 1 km (approximate...

Description of condition index value scores for estuarine tidal marsh along and within 10 km of the GCPO LCC Gulf Coast subgeography. A series of raster calculations were used in a dichotomous decision-based framework to compile a per-pixel draft condition index value at a 10 m resolution for GCPO estuarine tidal marsh based on the number of configuration and condition endpoints met within each marsh pixel. Pixels not identified as a estuarine marsh but that were identified as having the potential to be marsh were given a score of 1, provided the pixels were not classified as developed. Potential estuarine tidal marsh pixels were derived from a combination of potential estuarine tidal marsh classes in the Landfire...
