Summary: An indicator is a measure of a component or process in an ecosystem that can serve as a proxy for overall condition of the ecosystem. This project will create a structured framework to evaluate biological and socioeconomic ecosystem indicators collected by existing monitoring programs, assess their strengths and weaknesses, and make recommendations for a set of scientifically rigorous, practical, and cost-effective indicators for five key habitats (salt marsh, mangrove, seagrass, oyster beds/reefs, and coral reefs) across the Gulf of Mexico. To assemble the framework and make recommendations for a comprehensive set of indicators, the investigators will 1) catalog the indicators being used in existing inventory and monitoring programs; 2) develop conceptual ecological models and identify indicators of ecological integrity for the five major habitats to help managers understand critical ecosystem functions and stressors that affect ecosystem condition; 3) identify key ecosystem services provided by the habitats and identify indicators of their sustainability to elucidate the relationship between ecosystem condition and the services they provide; 4) summarize key indicators of ecological integrity and ecosystem services and identify thresholds for each; 5) hold workshops where experts will evaluate the models and proposed indicators; and 6) align selected indicators against current indicators used by existing monitoring programs across the Gulf to determine gaps and identify their strengths and weaknesses.
