USDA Forest Service

USDA Forest Service

The U.S. Department of Agriculture Forest Service is a Federal agency that manages public lands in national forests and grasslands. The Forest Service is also the largest forestry research organization in the world, and provides technical and financial assistance to state and private forestry agencies. Gifford Pinchot, the first Chief of the Forest Service, summed up the purpose of the Forest Service—"to provide the greatest amount of good for the greatest amount of people in the long run."

5487984 red trillium Trillium erectum Red trillium is found in rich, moist woods from Manitoba, Canada east to Nova Scotia, south to Georgia and Alabama, and north to Illinois and Michigan.? Red trillium, also known as Stinking Benjamin, has one nodding flower with an unpleasant odor rising from a stalk above the leaves. The flower is about 6.5 cm wide, with three maroon or reddish-brown petals. The leaves can be up to 17.5 cm long and are net-veined, rather than parallel veined, which is more typical of the lily family. Red trillium blooms from April-June, and can reach 20-40 cm in height. 
5487983 pink lady's-slipper Cypripedium acaule Pink lady's slipper is a large, showy wildflower belonging to the orchid family. It has two opposite basal leaves with conspicuous parallel veins and a large flower at the end of an erect stalk. The flower is magenta to whitish-pink; sometimes the whitish pink flowers will have darker pink venation. Rarely the flower may be all white. This plant grows 6 to 15 inches tall and flowers generally between May and July?.  Pink lady’s slipper lives in a variety of habitats, growing in mixed hardwood coniferous forests of pine and hemlock on rocky/mossy slopes, and in semi-open or in deep humus and acidic but well-drained soil under birch and other deciduous trees of eastern United States forests.?
5487979 squirrel corn Dicentra canadensis An inhabitant of the eastern hardwood forest, Dicentra canadensis seems to prefer rich soils with rocky outcrops. The deep ravines and river valleys of Minnesota's southeast counties represent the extreme northwest extent of Squirrel Corn's North American range. It is by no means common in that area. The DNR says it is now most at risk from invasive species, earthworms in particular, and was listed as a Special Concern species in 1984.?
5487978 red trillium Trillium erectum Red trillium is found in rich, moist woods from Manitoba, Canada east to Nova Scotia, south to Georgia and Alabama, and north to Illinois and Michigan.? Red trillium, also known as Stinking Benjamin, has one nodding flower with an unpleasant odor. The flower is about 6.5 cm wide, with three maroon or reddish-brown petals. The leaves can be up to 17.5 cm long, and are net-veined, rather than parallel veined, which is more typical of the lily family. The red trillium flowers from April to June, and grows from 20-40 cm in height.
