2023 Land Trust Learning Series


Join us for a special lecture on saltmarsh degradation by Dr. Mark Bertness. This is the first event in our 2023 Land Trust Learning Series.

Dr. Bertness will bring the challenge of saltmarsh degradation into focus. Coastal saltmarshes are one of the most valuable ecosystems on the Earth in terms of the services they provide humanity. Historically, however, marshes have been extensively ditched, drained and developed, motivating the conservation and restoration of remaining marshes.

Conservation of the surviving local marshes is not an easy task, since the most severe current threats are not local, but global. Eutrophication, invasive species, sea level rise, and overfishing lead to trophic collapse. These large-scale problems impact coastal wetlands across the globe. Dr. Bertness will examine how these factors,  individually and collectively, are leading to rapid degradation of Narragansett Bay marshes and the entire East Coast of North America.

Brown Professor of Ecology and Evolutionary Biology Emeritus at Brown University.
