A large ecoregion containing a large percentage of aspen and lowland shrub habitat, the two primary habitats used by Golden-winged Warblers.
The ecoregion supporting the state's largest concentration of Golden-winged Warblers, with at least 48 pairs documented during the Michigan Breeding Bird Atlas Part II, not all of which necessarily bred during the same year. All maximum single counts for each block were summed over the multiyear period of atlassing work. Since not all blocks were surveyed, this represents a very conservative minimum estimate of the actual # of pairs on territory within the IBA. This area encompasses a large portion of the focal area delineated by the GWWA working group in August 2010 in Ithaca, NY.
Lack of coordinated aspen management is leading to habitat reductions as stands outgrow the age classes used by Golden-winged Warblers. Increased aspen management is strongly suggested.
Mostly privately-owned, with roughly 20% of the land base falling under the Gladwin State Forest.
Two cover types are important to Golden-winged Warblers: lowland shrub (such as Speckled Alder), and young stands of aspen. These contribute to a combined 35% of the area of the IBA.
Very varied land use from agricultural/pastoral to forestry to recreational/housing.
