Project: Ecological and Economic Recovery of the Kennebec and Androscoggin rivers, estuary, and nearshore marine environment
Merrymeeting Bay is a freshwater tidal ecosystem in Midcoast Maine that supports a diverse and complex food web. Historically, migratory waterfowl and anadromous fish thrived in the bay. Human activities led to a collapse of the ecosystem in the second half of the twentieth century. Since then, water quality of the bay was able to rebound much faster than the biotic components of the bay. Improvements are still underway for populations of submerged aquatic vegetation, macroinvertebrates, and fish. Our research this summer focused on mapping vegetation and surveying anadromous fish populations in the bay. The mapping data will be added to a time series describing vegetation change over the past 50 years in the bay. Juvenile shad and river herring travel through the bay on their way to the Atlantic and submerged aquatic vegetation provides habitat for these important species. Weekly beach seines provided information on use of the bay by juvenile alosids and other fish species. Preserved stomach contents will be used to study juvenile alosid diet and promote an understanding of food web interactions in Merrymeeting Bay. In addition, social research focused on exploring perceptions of change on the Androscoggin and Kennebec Rivers through conducting interviews with stakeholders. Through interviewing a wide range of people, we can analyze the differences in the health and action on the two rivers. Economics research examined the scholarship of methods for valuing river restoration, examining hedonic pricing theory, travel cost method, and benefits transfer. The economics research culminated in running focus groups comprised of Maine residents in order to develop a contingent valuation survey to value different scenarios of river restoration.
These presentations are in PechaKucha format. PechaKucha is Japanese for ‘chit-chat’. It is a presentation methodology devised in 2003 in which 20 slides are shown for 20 seconds each. The slides auto advance to keep the presentations concise and quick paced. Each presentation is (about) 6 minutes and 40 seconds long.
