Description

Description

Grand Island is a mosaic of northern dry-mesic forest, floodplain forest, and open wetlands. Natural origin white and red pine dominate the dry-mesic forest with quaking aspen, northern red oak, and balsam fir also present. Dominant trees are generally 12-24 inches in diameter with some greater than 28 inches. Canopy diversity, size, and age distribution are moderate to good. The sub canopy is predominantly red maple and white spruce with significant amounts of pines. Embedded in the forest are scattered bedrock outcrops with a varying amount of tree cover depending on the soil depth. Canopy trees include a mix of red oak, red maple, white pine, and ironwood. More open areas have a mix of dry prairie and barrens vegetation with species such as poverty oat grass, harebell, pale corydalis, cow wheat, wild bergamot, and rusty woodsia. Dry 20-25 foot cliffs are present in several spots. The tall shrub layer is variable with hazelnut the dominant species. Ground flora is moderately diverse with characteristic species including bracken fern, Penn sedge, and hog-peanut. Shrubs include blueberries, hazelnut, and bush honeysuckle. The floodplain forest is dominated by large silver maple with green ash. The ground flora is of low diversity and likely due to the dense canopy and intermittent flooding. Ostrich fern, wood nettle and stinging nettle dominate. Sloughs and old stream channels are found throughout the island. Several rare and uncommon birds have been documented during breeding bird surveys. Grand Island is owned by the DNR 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.

Allowable activities

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.

  • Hiking
  • Fishing
  • Cross country skiing
  • Hunting
  • Trapping

Prohibited activities

  • Camping and campfires
  • Collecting of animals (other than legally harvested species), non-edible fungi, rocks, minerals, fossils, archaeological artifacts, soil, downed wood, or any other natural material, alive or dead. Collecting for scientific research requires a permit issued by the DNR
