Welcome to Southeastern Massachusetts Pine Barrens Alliance (SEMPBA)!
We are a non-profit, all-volunteer group dedicated to raising awareness about the need for urgent action to conserve the globally rare Coastal Pine Barrens of Southeastern Massachusetts.
We believe that by providing learning opportunities and building an action-oriented network of state and municipal agencies, conservation groups, tribes, businesses, and individuals, we can pool our resources and turn around the trend of deteriorating Coastal Pine Barrens habitat and move toward a future of cooperative living between humankind and the natural world.
SEMPBA is everywhere—doing everything we can to save the Coastal Pine Barrens!
Regional Collaboration
SEMPBA is proud to serve as coordinators for the Massachusetts Coastal Pine Barrens Partnership, one of 55 Regional Conservation Partnerships (RCPs) in the Northeastern United States. We believe that forming partnerships is the only way we can save the 40 natural communities that comprise this globally rare coastal pine barrens ecoregion.

Research

SEMPBA volunteers are involved in research projects ranging from saltwater intrusion into Plymouth's ground water, initiatives to engage citizens in regional climate change mitigation and preparation, and a variety of citizen science projects at The Center at the beautiful the Center Hill Preserve. Volunteers participate in the Massachusetts Department of Marine Fisheries Spawning Horseshoe Crab survey each spring. We beleive in fun with a purpose and encourage you to join us!
Education and outreach in a beautiful setting!
SEMPBA offers trainings and workshops to advance conservation within the Coastal Pine Barrens Ecoregion. Our Climate and Nature Center (above), located at the beautiful Center Hill Preserve, boasts at least eight natural communities— from beach to forest and in between—making it a wonderful nature education site. We invite schools, conservation groups, nature lovers and visitors of all types to enjoy the preserve. When you do, stop by SEMPBA's Climate and Nature Center to learn more about our unique ecoregion. What you discover may inspire you—the way it has inspired SEMPBA volunteers—to do all you can to save our Coastal Pine Barrens!

It includes a globally rare coastal plain pond, Great South Pond. The intact ecosystem supports a vast array of globally rare plants and animals and an Atlantic Coastal Pine Barrens forest.
