Sustainable Forest Lands


Maine's growth-to-harvest ratio is stable

No significant movement since the last available data

Benchmark: A net growth-to-removal ratio of approximately 1:1 will be maintained over time.

Overview Fig. A


The sustainable management of Maine’s forests is measured by the growth to harvest ratio. A net growth value above one means growth exceeds harvest, and a value below one means harvest exceeds growth. Forests cover nearly 90% of Maine’s land area. Private landowners manage 94% of forested acreage, with much of it accessible to the public. Forests provide habitat for wildlife, help protect air and water quality, offer recreational opportunities, and supply raw materials for products ranging from paper to alternative fuels. Sustainable forestry supports Maine’s economy, environment, and quality of life.

Since 2010, Maine has maintained net forest growth-to-removal ratios slightly in favor of growth over harvest. The growth-to-harvest ratio fell slightly from 1.38 in 2018 to 1.27 in 2019.
