MA H952

Requires all Commonwealth-owned watershed lands to be designated as either "Parks" (allowing recreation and facilities maintenance with limited vegetation management) or "Reserves" (permanently protected areas with minimal human intervention to allow natural forest processes)

Prohibits the sale, removal, or destruction of timber and natural resources on both Parks and Reserves, with limited exceptions for public safety, erosion control, invasive species management, and maintaining existing trails and fields

Creates an 8-member "Reserves Scientific Advisory Council" including experts from Harvard Forest, Highstead Foundation, Center for Biological Diversity, Native Plant Trust, Woodwell Climate Research Center, and UMass to oversee Reserve designation and management

Bans new commercial solar arrays, wind turbines, gas pipelines, cellular towers, and other industrial infrastructure on watershed lands, with narrow exceptions for solar powering existing public facilities

Requires watershed management plans to be adopted at least every 5 years following public review, and mandates the Council submit biennial reports to the governor on Reserve conditions
