The Trust for Public Land conducted an economic analysis of the return on the Commonwealth’s investment in land conservation through a variety of state funding programs and found that every $1 invested in land conservation returned $4 in natural goods and services to the Massachusetts economy. In addition, land conservation funded by the Commonwealth supports key industries that depend on the availability of high-quality protected land and water. Massachusetts has also been successful in leveraging funding support from other sources, expanding the impact of the Commonwealth’s investment. This report summarizes the key findings and the benefits of parks and open space investments by Massachusetts.
