Alger and Schoolcraft
Shingleton bog is an outstanding example of the Shingleton Fen Landtype Association, which is a large wetland complex formed in outwash sand reworked by Lake Algonquin. The RNA includes areas of mixed hardwood forests, patterned fens, and open bogs with associated conifers, northern dry forest, and riparian areas. The northbranch of Stutt’s Creek and one of its unnamed tributaries flow through the RNA.

Ecological Information

Physical and Climatic Conditions

Nearest weather station, with distance and direction from RNA:
Munisingis the nearest weather station, (I.D. # 5690, latitude 46 ̊24’N, longitude -86 ̊39+’W). The station is about tenmiles due southeastof the RNA.
Annual precipitation (type, seasonal distribution) :
Annual precipitation averages 35inches (88cm);23% received during the growing season. Average seasonal snowfall is 108inches (275cm).
Maximum and minimum temperatures:
Daily spring/summer temperatures average 51° F;average daily maximum temperatures average 51° F. Average temperature in the fall/winter is 31° F; averagedaily minimum temperatures average 30° F.
Elevations range from 785feet (238m) to 838feet (254m) MSL.
Geology and Soils:
The bedrock geology of the RNA is of the Ordivician Black River Group and the Trenton Group, while the surface geology is comprised of peat and muck as well as glacial outwash sand and gravel.The majority of the soils within Shingleton Bog fall under the Rubicon Series and the Kalkaska-Tawas-Carbondale Association. This series is described as well-drained, nearly level to very steep soils on outwash plains, lake plains, moraines, and dunes. The fen soils are nearly level and very poorly drained organic soils. These soils formed in sandy material.
Aquatic Features:
he north branch of the Stutt’s Creek and one of its unnamed tributaries flow through the RNA. Also, a large portion of the RNA is wetland.

MI Natural Community Types:
Based on the Michigan Natural Features Inventory natural community types, Shingleton Bog RNA is composed of the following: 73% Hardwood-conifer Swamp, 15% DryNorthern Forest, 8% Patterned Fen, and 4% Poor Fen.
Common Flora:
Hardwood-Conifer Swamp and Fens: Thuja occidnetalis (northern white cedar), Picea mariana (black spruce), Osmunda cinnamomea, O. regalis (cinnamon and royal fern), Lycopodium spp. (clubmosses), Equisetum spp. (horsetail), Gaultheria procumbens (wintergreen), Trientalis borealis (starflower), Cornus canadensis (bunchberry), Drosera spp. (sundew) and Sarracenia purpurea (pitcher plant), and Carex spp. (sedges).
Dry Northern Forest: Tsuga canadensis (eastern hemlock), Pinus resinosa and P. strobus (red and eastern white pine), Acer rubrum and A. saccharum (red and sugar maple), some Thuja occidentalis (northern white cedar), scattered areas of Fagus grandifolia (American beech), Betula alleghaniensis (yellow birch), Picea mariana (black spruce), and some Prunus pensylvanica and P. serotina (pin cherry and black cherry)
Common Fauna:
Shingleton bog is home to many of the birds and mammals common to this region, it is also home to the following species of State Concern: American bittern (Botaurus lentiginosus), northern harrier (Circus cyaneus), gray wolf (Canis lupus),and moose (Alces alces).
Potential Research Topics:
Shingleton Bog RNA provides an opportunity to study poor or patterned fens and make comparison with those with more pristine characteristics. The population of rare orchids also presents unique research opportunities. Other topics may include fire succession, invasive species, and climate change impacts on fens and northern wetlands.
