History of our Partnership with The Lincoln Land Trust and the Town of Lincoln

Lincoln is a wonderful place for a nature-based school because about 40% of the town is in conservation and Lincolnites’ passion for the land is almost palpable. The Land Trust (the oldest private land trust in the country) has a visionary staff and, in January of 2016, we signed an MOU with the Land Trust. Approved by the boards of both organizations, the MOU declared that we would collaborate on developing curricular materials and also that the Land Trust would help Birches find a property near conservation land where we could develop informal “outdoor classrooms.” We believe that our formal collaboration with the Land Trust is the first of its kind in the country. In November of 2016, the Land Trust and Birches School purchased a 16-acre property, 9 acres of which has gone into conservation. Our new school is housed on 4 acres, and the remaining 3 acres were purchased by the town of Lincoln in March 2017 to build a badly needed athletic field. We are very grateful that these three Lincoln entities could realize individual goals in a remarkably collaborative way, conserving and making environmentally-sound use of precious land in the Greater Boston area.
