The GNDNERR is a reference site for many research studies and on-going restoration projects across the Mississippi Coast, but management questions remain specifically in terms of feral hog management, terrapin nesting success, occurrence of rare and endangered species, etc. Therefore, population distribution and ecological studies for terrestrial and aquatic vertebrates are needed to increase understanding of these species’ population dynamics in GNDNERR and allow GNDNERR to serve in its role of a reference estuary.
