About the Sunapee Uplands

The Sunapee Uplands is a small, mostly-forested region located entirely in New Hampshire, towards the southwest of the state. This area tends to be cooler and higher-elevation than regions to the east, west, and south, but warmer and lower-elevation than regions to the north, and has a diversity of forest types owing to diverse terrain.

This region is a rolling plateau with hills and monadnocks throughout. The drainage patterns have been disrupted by glaciation, and there are numerous natural ponds and lakes throughout, as well as artificial reservoirs. The Pemigewasset River flows briefly through this region, but in most of the region there are only smaller streams. The bedrock in this region is a mix of igneous and metamorphic rocks, and the surface is covered mostly with sandy glacial till, with some sandy-loamy till. The climate is humid and continental, with high precipitation.

Original forest cover here was a mix of northern hardwood and transitional hardwood-coniferous forests, with some lowland spruce-fir forest. Northern hardwood forests featured American beech (Fagus grandifolia), yellow birch (Betula alleghaniensis), and sugar maple (Acer saccharum) as dominant trees, with some red maple (Acer rubrum), white ash (Fraxinus americana), and American basswood (Tilia americana). Drier sites featured northern red oak (Quercus rubra) and eastern white pine (Pinus strobus). Some sites also featured red oak-sugar maple forest, with northern red oak, sugar maple, American beech, sweet birch (Betula lenta), and some eastern white pine. There were also hemlock forests, hemlock-beech-northern hardwood forests, and hemlock-beech-oak-pine forests featuring eastern hemlock (Tsuga canadensis), American beech, northern red oak, and eastern white pine. At higher elevations, lowland spruce-fir forests featured red spruce (Picea rubens), balsam fir (Abies balsamea), paper birch (Betula papyrifera), and yellow birch. The highest peaks supported montane spruce-fir forest.

Low-lying wetlands supported black spruce (Picea mariana), red maple, and some atlantic white cedar (Chamaecyparis thyoides) swamps. River floodplains had forests of red maple, silver maple (Acer saccharinum), sugar maple, black cherry (Prunus serotina), and American elm (Ulmus americana).

This area was more utilized for agriculture in the past, but most of it has been abandoned and much of the land has returned to forest. There is a small amount of pastureland and hay production remaining. The region also is used for forestry, tourism and recreation, and hunting and fishing. There is some rural residential development, and there are also some protected lands, including both state parks and wildlife management areas. Most of the region is sparsely populated, but there are some towns located in the valleys.

This region is bordered to the south and southeast by the similar but slightly warmer Worcester/Monadnock Plateau, to the west by the slightly lower-elevation Vermont Piedmont, to the north by the White Mountain Foothills, and in a small border to the east by the Sebago-Ossipee Hills and Plains.
