After nearly two years of collaboration and fundraising, The Ausbon Sargent Land Preservation Trust closed on the Stoney Brook Project in Newbury, NH. In July of 2012, the Ausbon Sargent Board approved the decision for the land trust to be a part of the project and Ausbon Sargent joined the newly formed Stoney Brook Conservation Alliance. The total estimated project cost was $291,000, including the property purchase and other expenses such as survey, legal costs, appraisal and stewardship (forever).

In 1949, property owner, Libby Trayner purchased her property on Shaker Street and Mountain Road near the New London/Sutton town line and moved with her parents to the home she built on the property. In 1988, Libby, who had no direct heirs, began having conversations with Debbie Stanley, Executive Director of The Ausbon Sargent Land Trust, about conserving her property. Since Libby was not sure if she would ever need to liquidate any of her land as she grew older, she chose to name Ausbon Sargent in her will, posthumously gifting the land trust an easement on any remaining property.

It was a six months of effort to bring the last two conservation easements in line for R.H. Webb Forest Preserve, a family Tree Farm that is managed from Sunapee by Van Webb. These last two properties are in a line of easements that the Webb family has completed with Ausbon Sargent and others over the last several years. Van comments, "It has been a very interesting learning experience to say the least! On each parcel that we have done, there is always something new and different that we learn about a particular piece of land.

Van Webb and the V-Oz Asset Management Company, LLC have granted a conservation easement on 37 acres of undeveloped land with frontage on three roads in Sunapee. Accessible from Stagecoach Road, Harding Hill Road and Rte 103, this property is predominately forested, with a network of trails. The land is currently being managed for Red Oak and White Pine. It also has about 18 acres that are classified as wetland. This mix of forest and wetland results in great wildlife habitat, with deer, moose, fox and owls all present on the property.

On April 26, 2019, The Ausbon Sargent Land Preservation Trust closed on the 94-acre Webb/Crowell Forest, its newest conservation easement, located in Sutton on Eaton Grange Road West. 

Two years prior, in August of 2017, Ausbon Sargent was given an 8-acre parcel of land in the Town of Sutton.  This 8-acre property was adjacent to the 86-acre Webb/Crowell Forest which is owned by the Town of Sutton.  Because of their proximity, in the spring of 2018, Ausbon Sargent gifted the 8 acres to the Town of Sutton.  

The Wendell Marsh North Property is primarily undeveloped forest land with scattered small wetlands and approximately 2200 feet of frontage on both sides of the outlet stream from Perkins Pond. A portion of the property is in the Wendell Marsh watershed and helps maintain the quality of the water flowing into the marsh, an important wildlife area. A variety of wildlife habitats are on the property and the Lake Sunapee Snowmobile Club maintains a snowmobile trail on the property that is used year round for pedestrian and snowmobile recreation.

The Paul property, which is now owned by the Town of Sutton, NH, has been named the "William Bean Quarry." It is an undeveloped, primarily forested 139-acre parcel offering a great asset to the Town of Sutton and all who enjoy exploring the outdoors. The property has a reported rare or endangered species listing under the New Hampshire Natural Heritage Bureau. The "William Bean Quarry" is open to the public for low impact, non-commercial outdoor recreation, including snowmobiling and it provides scenic enjoyment to the public as they hike and travel along King Hill Road.

Ann and Marc Davis of Wilmot, NH, have named this land "Woods Without Gile" – cleverly revealing its location, which is bordered on three sides at the eastern edge of the 6,725 protected acres of the John F. Gile Memorial State Forest.

At the end of road and nearly at the top of Morgan Hill, Sarah and David Yerkes protected their property from any further subdivision. By donating a conservation easement they preserved a truly spectacular view of Pleasant Lake and Mt. Kearsarge, protected multiple trailhead access, maintained open space, and saved forestland for water resources protection and wildlife habitat. An additional goal of the Yerkes with their easement was to prohibit the use of their land to satisfy density requirements with respect to the development of other properties.
