Overview

Location

Dunn County. T30N-R12W, Section 16. 404 acres.

Description

Description

Situated on rolling topography, Otter Creek Oak Barrens contains an undisturbed oak barrens dominated by scattered large black and Hill's oaks with groves of smaller bur, black, and white oak. Jack pine and trembling aspen are also present. The large black oaks are at least 140 years old, and may be over 200 years old. The smaller oaks, 8 to 20 inches in diameter, are 70 to 110 years old. The moderate shrub layer contains American hazelnut and dogwood brush. The groundlayer is quite diverse with a rich assemblage of prairie grasses and forbs including prairie larkspur. Other species are June grass, little blue-stem, leadplant, puccoon, field wormwood, flowering spurge, bastard-toadflax, false Solomon's seal, bird's-foot violet, prairie coreopsis, and New Jersey tea. Pocket gophers are abundant. The surrounding southern dry forest has a high density of oaks with canopy trees mostly single stemmed on the slopes and multiple stemmed on the upper slopes and ridges. The forest has an excellent uneven canopy replacement structure and a groundlayer dominated by twisted stalk. On a few north facing slopes the dominant tree is red maple with an open understory and a groundlayer dominated by interrupted fern. The soils are sandy and sandy loams. Otter Creek Oak Barrens is owned by the DNR and was designated a State Natural Area in 1990.

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.

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.

Entrance fees: Excepting Parfrey's Glen, the Cambrian Outlook in the Dells of the Wisconsin River, SNAs within State Parks and some within State Forests, all other DNR-owned SNAs do not have any admission fee. For more information, see Wis. Admin. Code NR 45. For non-DNR-owned SNAs, we are unaware of any vehicle or admission fees. However, please contact the landowner for more information.
