The Roxbury Land Trust has announced it has achieved national accreditation.

The Roxbury Land Trust is one of only 15 Connecticut land trusts to receive accredition. The land trust met extensive documentation requirements and underwent a comprehensive review as part of its accreditation application.

Accredited land trusts across the country have permanently conserved more than 15 million acres of farms, forests and natural areas that are vital to healthy, vibrant communities.

“Accreditation demonstrates the Roxbury Land Trust’s commitment to permanent land conservation in Roxbury and surrounding communities,” said Susan Payne, executive director of Roxbury Land Trust.

“We’re a stronger organization for having gone through the rigorous accreditation process and this strength will help make our area an even better place for our residents and future generations,” she said.

Since it was established in 1970, the Roxbury Land Trust has preserved 3,630 acres of farmland, woodlands, wildlife habitats, watercourses, wetlands and open space in Roxbury and neighboring communities.

The nonprofit organization maintains 32 preserves with 30 miles of hiking trails, three active farms and historic iron and granite mines, as well as offers a range of educational programs.

Many of the properties, which help preserve Roxbury’s rural character and scenic beauty, have been donated by area families through the years.

“We are honored to join more 342 other land trusts across America that demonstrate their commitment to professional excellence through accreditation,” said Brian Duda, president of the Roxbury Land Trust.

“Although the Roxbury Land Trust has always been well-run and well-respected in its land preservation and stewardship efforts, this national seal of approval will help to maintain the public’s trust in our work,” he said. “It is a proud day for Roxbury.”
