Best Management Practices for Golden-winged Warbler Habitat in Shrub Wetlands of the Great Lakes

Best Management Practices for Golden-winged Warbler Habitat in Shrub Wetlands of the Great Lakes
Shrub wetlands are extensive in the region, particularly in the western Great Lakes. Not all shrub wetlands are occupied by Golden-winged Warbler for a variety of reasons including high water levels, lack of desired woody and herbaceous vegetation patchiness, lack of scattered canopy trees, and distance to upland deciduous forest. Dense mature stands of unbroken woody shrub cover over large areas often are unsuitable. Reduced flooding and beaver activity may be partially responsible for these conditions and restoration of these natural disturbance regimes could improve habitat quality. In other cases, mechanical treatments provide the mechanism for creating or restoring breeding habitat (Figure 1) and are the focus of the included guidelines. For this insert, shrub wetlands are defined as palustrine wetlands dominated by broad-leaved deciduous woody vegetation less than 20 feet tall. The species include true shrubs, young trees, and scattered trees of varying size. See Table 1 for common dominant shrub and tree species.
