Other Information

High Flats State Forest covers 2018 acres. The topography is variable with upland areas supporting a mixture of northern hardwood, hemlock, and white pine forests. Pine and spruce plantations were established on what were formerly farm fields and pastures. Flatter ground supports open wetlands and shrub swamps, which gradually transition to spruce-balsam fir and swamp hardwoods stands in poorly-drained areas.
