No. 676

Mullet Creek White Cedar Wetland contains a good quality northern wet-mesic forest of medium age dominated by northern white cedar up to 28 inches in diameter. Also present is tamarack and some black ash. The ground layer contains typical northern wet-mesic forest associates such as three-leaved gold-thread, American starflower, and Canada mayflower.

There are good amounts of swamp lousewort which indicates calcium-rich water and increases the likelihood of more fen species being present. Several rare forest interior birds have been found on or adjacent to this site. Maintaining large blocks of forest with high canopy cover and good structural diversity including a good shrub layer will be beneficial for all birds present. Mullet Creek White Cedar Wetland is owned by the DNR and was designated a State Natural Area in 2016.

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. 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 a detailed topographic map are useful tools for exploring larger SNAs.

Entrance fees: Except for 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 fees.

Allowable activities: DNR-owned land

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 below and posted with signs on the property site.

Driving directions

From the intersection of County A and State Highway 23 in Greenbush, go west on Highway 23 for 7.1 miles, then south on Banner Road for 1.7 miles to its end and a DNR parking area. Walk due south 0.5 miles and then due west about 0.4 miles on DNR land into the site.

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.
