Within Governor Knowles State Forest and the St. Croix National Scenic Riverway, Polk County. T36-R19W, Sections 4, 5, 31, 32. T36N-R20W, Sections 34, 35, 36. 984 acres.
Located in pitted outwash deposits laid down by glacial melt-water streams, Sterling Barrens contains a jack pine-Hill's oak dry forest interspersed with barrens openings and an extensive wetland of sedge meadow and shrub-carr. The gently rolling barrens openings are interspersed with prairie species. Dominant grasses are needle grass, three-awn grass, Indian grass, and big and little blue-stem. Several rare forbs are at or near their natural eastern range limit. Included in the natural area are the St. Croix River terrace escarpment and a reach of the St. Croix that contains an excellent diversity of aquatic species. The river is lined with bottomland hardwoods of silver maple, elm, black ash, and cottonwood with willow brush. Many dragonfly species are found in this portion of the river. The dry forest on the sandy uplands and the terrace slope is young but has a diverse groundlayer. Adjacent to the river is a sedge meadow dominated by wide-leaved sedges, prairie cord grass, marsh fern, sensitive fern, blue-joint grass, wool grass, ironweed, and Joe-pye weed. Shrub-carr areas consist primarily of willows with white meadowsweet, alder, and occasional tamarack. Low areas support stands of emergent aquatics including arrowhead, cat-tail, three-way sedge, river bulrush, hardstem bulrush, and spike rushes. Breeding bird surveys show broad winged hawk, red-eyed vireo, chestnut-sided warbler, ovenbird, and chipping sparrow as common nesters. Sterling Barrens is owned by the National Park Service and DNR. The site was originally designated a State Natural Area in 1979 and later expanded to include the St. Croix Scenic Riverway in 2002.

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.
To create your own custom map where you can zoom to a specific location, please use the DNR's mapping application.
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.
The good majority of SNAs are isolated and have few or no facilities. Some SNAs have vehicle access lanes or parking lots, but their accessibility may vary depending on weather conditions. Parking lots and lanes are not plowed during winter. Hiking trails may be nonexistent or consist of undeveloped footpaths. A GPS unit or compass and detailed topographic map are useful tools for exploring larger SNAs.
This SNA has multiple landowners: Opportunities for hunting and trapping depend on the land owner. In general, most DNR-owned land allows hunting and trapping. Partner-owned land may have other rules (for example, university-owned lands do not allow hunting or trapping). Please contact them directly to find out about their rules for hunting and trapping. You can find a link to other owner websites under the "Resource links" heading above. More details regarding allowable uses on the non-DNR land may be found under the "Access" tab above, if available.
In general, the activities listed below are allowed on all DNR-owned SNA lands. Exceptions to this list of public uses, such as SNAs closed to hunting, are noted under the "Access" tab above and posted with signs on site.
