In 2001, Katharine Brown of Warner donated a conservation easement on her land along the Henniker town line, adjacent to the Ashenden State Forest. The easement, which encompasses a 7-acre "Homestead Area" including an 1809 historic single family farm house, will be protected from any further residential development and will be maintained in perpetuity as open space. The Town of Warner Conservation Commission holds an executory interest in this conservation easement.

The land includes a large wetland and two man made ponds, and is bisected by the Warner Brook, which flows into the Contoocook River. It supports a significant number of bear, beaver, deer, moose and other wildlife species.

A staunch believer in preserving land for public benefit, Mrs. Brown previously donated the 165-acre Ashenden State Forest to the State of New Hampshire.

Katharine Brown sold the property to John and Mary Ellen Moretto in December 2003. Katharine passed away in 2005. On May 2, 2017, Spencer Roy purchased this property from the Moretto's.
