The New England Wildflower Society is based at the Garden in the Woods in Framingham, Massachusetts but its interests and activities cover all of New England. "From this base, 25 staff and more than 700 volunteers work throughout New England to monitor and protect rare and endangered plants, collect and preserve seeds to ensure biological diversity, detect and control invasive species, conduct research, and offer a range of educational programs. The Society also operates a native plant nursery at Nasami Farm in western Massachusetts and has seven sanctuaries in Maine, Massachusetts, New Hampshire, and Vermont that are open to the public." Please see their website for more information.
White Birch, Betula papyrifera, also known as the paper birch, is the state tree of New Hampshire. The bark is highly weather resistant. A fallen tree may rot from the inside out leaving just the white bark. White Birch along with other forest trees can be managed to their full potential through silviculture.

Plainfield Sanctuary located in Plainfield, New Hampshire is an area rich in wildflower and fern specimens that are uncommon in New Hampshire. There aren’t any trails in the 86 acre sanctuary but many of the plants can be seen from the road. This site has been designated a “unique area” by the State of New Hampshire’s Critical Areas Program. The image above is the Cardamine concatenata (cutleaf toothwort), a native perennial of the eastern United States. It is considered one of the spring ephemeral woodland bloomers.
