Pepperell's Open Space & Recreation Plan has been updated five times since 1969, most recently in February 2005 thanks to the input of citizens, and has become an important planning resource for the Town and Town Board as they manage current and future growth.
The Nashoba Conservation Trust is a non-profit land trust based in Pepperell MA with over 300 acres of protected land, many of which have hiking trails.
Since 1969, the Nashua River Watershed Association has been dedicated to the enjoyment and preservation of the lands around the Nashua River, including those in Pepperell. The NRWA's original charge involved the dramatic clean-up of the riverway, then-polluted by years of un-regulated use by the area's paper, shoe, and textile factories. Today, the Nashua River is a beautiful and vibrant resource for Pepperell and surrounding towns.
