BANGOR — A Maine-based forest management company is expanding into New Hampshire, Vermont and New York by acquiring a company that operates in those states.

Prentiss & Carlisle President Donald White says the acquisition of Upland Forestry adds nearly 270,000 acres to the 1.5 million acres the company manages in six states and Quebec.

White says that with the acquisition of Upland Forestry, Prentiss & Carlisle becomes one of the largest multiregional forest management firms in the country.

Prentiss & Carlisle is based in Bangor. Upland Forestry is based in Bristol, Vt., and has offices in New Hampshire and New York.
