Description

Description

Parfrey's Glen, Wisconsin's first State Natural Area, is a spectacular gorge deeply incised into the sandstone conglomerate of the south flank of the Baraboo Hills. The exposed Cambrian strata provide excellent opportunities for geological interpretation. The walls of the glen - a Scottish word for a narrow, rocky ravine - are sandstone with embedded pebbles and boulders of quartzite. The moss-covered walls are moist from seepage, cool and shaded. As a result, they support a flora more typical of northern Wisconsin with yellow birch, mountain maple, and red elder and several rare plant species, including the federally threatened northern monkshood (Aconitum noveboracense) and state-threatened round stemmed false foxglove (Agalinus gattingeri). Other rare species are cliff goldenrod (Solidago sciaphila), and two state-threatened birds, the cerulean warbler (Dendroica cerulea) and Acadian flycatcher (Empidonax virescens). Parfrey's Glen Creek, a fast, cold, hardwater stream flows through the gorge and harbors a very diverse insect fauna including a rare species of diving beetle (Agabus confusus) and a rare caddisfly (Limnephilus rossi). Parfrey's Glen is owned by the DNR and was designated a State Natural Area in 1952.

Access

Driving directions

Parfrey's Glen is now open after being closed from significant flash flooding received last year.

From the intersection of Highways 78 and 113 in Merrimac, go north and west on 113 about 4.8 miles, then east on County DL 2.1 miles to a parking area on the north side of the highway. A trail leads north into the glen.

Visitation Guidelines: Parfrey�s Glen is open daily 6:00 a.m. - 8:00 p.m. Visitors must remain on the trail. Pets, food, and beverage are not allowed in the natural area. A State Park sticker is required.

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.

Management

Site objectives

Manage the site as a reserve for southern dry-mesic forest and cliff communities, as a rare plant protection site, as a significant geological and archaeological site, and as an ecological reference area. Natural processes will primarily determine the structure of the forest and cliff communities. Provide opportunities for research and education on the highest quality native southern dry-mesic forests and cliff communities.

Management approach

The native dominant tree species (primarily yellow birch and oak), are managed passively, and will convert over time to a more mesic forest condition. Passive canopy management will determine the ecological characteristics of the site. The old field areas at the base of the hill will be allowed to succeed naturally to a forested condition. Augmentation of the ground layer in the old field will only add species that historically would have been found on the site, using seeds or plugs from local genetic material species; this usually occurs in the early stages of restoration. Other allowable activities include control of invasive plants and animals, maintenance of existing facilities, and access to suppress wildfires.

Site-specific considerations

• Although removal of hazardous trees from over and near state-approved trails and field roads is an allowed activity, manipulation/removal of vegetation and soil disturbance must be minimized, and must have no impact on the rare species found at the site
• Roadside easement areas may be managed sporadically by the designated local, county or state managers

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.

DNR-owned lands

See the "Ownership" tab above to determine if this State Natural Area is DNR-owned, 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.

Non-DNR lands

Many State Natural Areas are owned by DNR partner organizations and agencies. See the "Ownership" tab above to determine ownership of this SNA. Allowable recreational uses on partner-owned sites, and the rules governing them, may differ from those permitted on DNR-owned SNAs. Specific rules, especially for hunting and trapping, vary depending on the partner’s policies, and some may require a special permit. More details regarding use of partner-owned SNAs may be available under the "Access" tab above. If this SNA is owned by a partner, a link to the partner website is found at the top of this page. Please contact partners directly for more information on activities allowed on this property.
