Holmboe Conifer Forest features a variety of old-growth northern forest types on very steep morainal topography along the south bank of the Pelican River. A hemlock forest occupies the north-facing and lower ridge slopes. The drier sites are wooded with white and red pines, white birch, and a mixture of northern hardwoods. The north-central portion is occupied by a black spruce and tamarack wet forest. Canada yew occurs along a seepage area located between the moraine hills on the south and the swamp conifer forest near the river. Holmboe Conifer Forest is owned by The Northwoods Land Trust and was designated a State Natural Area in 1983.
