Summary

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 KIRA home range) [...]

Purpose

The Gulf Coast Joint Venture (GCJV) is a bird habitat conservation partnership that spans the coastal portions of AL, MS, LA, and TX. It is one of 18 bird habitat joint ventures in the U.S. The mission of the GCJV is to advance the conservation of important bird habitats within the GCJV region through biological planning, implementation of habitat conservation actions, and focused monitoring and evaluation of the planning and implementation process. King Rail (KIRA) is a priority bird species selected for conservation planning and habitat delivery in the GCJV region. It utilizes fresh-to-intermediate salinity emergent marsh and rice fields for breeding and wintering habitat. The GCJV identified areas of brackish marsh with appropriate vegetative structure that could be targeted for conservation actions designed to bring salinities into the intermediate range and provide King Rail habitat.
