The Southeastern Massachusetts Tree Wardens’ and Arborists’ Association (SEMTWAA) was organized in 1947 as a satellite organization of the MTWFA. In that era, there were five or six similar groups representing various regions of the state. Each arranged its own programs and considered subjects of local interest. Until 2015, when the Western Mass. group reactivated, SEMTWAA was the only such group still in existence. It is now an independent entity with its own officers and board. A Plymouth County representative and several other SEMTWAA members serve on the MTWFA board, ensuring communication and cooperation between the two associations.
