Wisconsin State Natural Areas Program Boscobel Bluffs (No. 683)

Overview

Location

Grant County. T8N-R3W, Sections 25, 26, 35, 36. 384 acres.

Description

Description

Boscobel Bluffs form part of the uplands that define the south flank of the Lower Wisconsin River valley. Unique wind-blown features, rare dry prairie habitat, as well as oak savanna woodlands are found here. The natural area exhibits a diversity of topographic reliefs and exposures, from steep, wooded draws and north-facing hillsides, to level ridgetops and open, south-facing slopes. The summit of the bluff lies some 300’ above the wide, sandy terraces of the river to the north. Prevailing westerly winds over the post-glacial eons have moved some of these sands into the draws and up higher on the flanks. The dry prairie is situated on a west-facing slope with rock outcrops and small sandstone cliffs. Many representative species occur here including big bluestem, hairy grama grass, bottlebrush grass, leadplant, silky aster, and blazing star. Along the ridge top and the south and west-facing slopes is an extensive oak opening with open grown bur oaks with shagbark hickory and American hazelnut. Many Species of Greatest Conservation Need are present here. The oak/hickory dominated forested portions of the site were also likely oak opening in the past but have succeeded to oak woodland in the absence of fire. Woody brush and invasive species management along with prescribed burning will improve the site’s integrity and help maintain it into the future. Boscobel Bluffs is owned by the Mississippi Valley Conservancy and was designated a State Natural Area in 2017.

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.
