Overview

Location

Within the Chequamegon-Nicolet National Forest. Oconto County. T33N-R16E, Section 36. T33-R17E, Section 31. 113 acres.

Description

Description

The core and highlight of North Branch Bottoms is the bottomland hardwood forest along the North Branch of the Oconto River. The floodplain forest is dominated by black ash, red maple, and large silver maple with a groundlayer of nettles and ostrich fern. Steep, rocky slopes border the floodplain with pockets of fire-scarred hardwoods on the slope with super-canopy white pine found along the river corridor. An isolated stand of remnant old-growth hemlock and American beech forest is included in the complex. Rare plant and bird species are found here. The understory is dominated by beech seedlings, maple-leaf viburnum, and witch hazel. Other plants include bracken fern, and hog-peanut. Upland stands are primarily red oak, sugar maple, and paper birch with some richer inclusions of sugar maple and basswood. Rare and uncommon species include butternut (Juglans cinerea), Indian cucumber-root (Medeola virginiana), and the state-endangered little goblin moonwort (Botrychium mormo). The rich understory is dominated by hog-peanut with maidenhair fern, lady fern, spikenard, round-lobed hepatica, bloodroot, and large-flowered trillium. A disjunct hemlock stand is found west of the complex. The rare pygmy shrew (Sorex hoyi) has been found just outside the SNA/RNA boundary and sufficient habitat exists within the site to support it. A complete survey may reveal the occurrence of this and other rare species within the site. North Branch Bottoms is owned by the US Forest Service and was designated a State Natural Area in 2007.

Maps

The DNR's state natural areas program is comprised of lands owned by the state, private conservation organizations, municipalities, other governmental agencies, educational institutions and private individuals. While the majority of SNAs are open to the public, access may vary according to individual ownership policies. Public use restrictions may apply due to public safety, or to protect endangered or threatened species or unique natural features. Lands may be temporarily closed due to specific management activities. Users are encouraged to contact the landowner for more specific details.

The data shown on these maps have been obtained from various sources, and are of varying age, reliability, and resolution. The data may contain errors or omissions and should not be interpreted as a legal representation of legal ownership boundaries.

Recreation

Very few State Natural Areas have public facilities, but nearly all are open for a variety of recreational activities as indicated below. Generally, there are no picnic areas, restrooms, or other developments. Parking lots or designated parking areas are noted on individual SNA pages and maps. Trails, if present, are typically undesignated footpaths. If a developed trail is present, it will normally be noted on the SNA map and/or under the "Access" tab. A compass and topographic map or a GPS unit are useful tools for exploring larger, isolated SNAs.

Non-DNR lands
