SHELBURNE â An ambitious program announced by the non-profit Mahoosuc Land Trust less than a year ago to permanently conserve nine mainland parcels and 30 islands along an 8.7-mile stretch of the Androscoggin River has become a reality. The $780,000 property purchase was finalized Friday and the deeds registered in the Coos County Courthouse in Lancaster. The closing of the 861-acre Shelburne Riverlands project was handled by Andrew Dean, a partner at Cooper Cargill Chant P.A. of North Conway and Berlin. Bayroot LLC sold the acreage being managed by Wagner Timber Management of Lyme. The parcels were previously owned by Mead/Westvaco Corp.
