Dan's Mountain is prime habitat for many species of songbirds that only nest in forests. These birds, like the scarlet tanager, yellow-throated vireo and ovenbird, use the shelter of dense woods to protect their eggs and young. In the spring and summer, the forest is filled with bright flashes of color as the birds fly from tree to tree, singing out their territorial claims. The Audubon Society has designated Dan's Mt. a State Significant Bird Area.

Dan's Mountain WMA, located in western Allegany County, includes the largest contiguous state-owned forest in Maryland. The steep ridges of the mountain, ranging from 900 to 2,800 feet, yield a breathtaking view of the North Branch of the Potomac River and its forested valley. Approximately 98% of this 9,925-acre tract is dominated by mixed oak forest in various age classes.
