For a full list of references used to create this description, please refer to the natural community abstract for Southern Hardwood Swamp. This abundance of plant species in Michigan swamps is partially due to the higher levels of inflow and outflow of the surface waters (Prince 1997). Substrate pH is also highly variable. Groundwater seepage affects species composition and structure. In addition, the pit and mound microtopography generates fine-scale gradients of soil moisture and soil chemistry and provides a diversity of microsites for plant establishment. Removal of coarse woody debris or senesced trees from hardwood-conifer swamps should be avoided or minimized to ensure the continued viability of the system.

NMH has expanded and grown to include a forestry crew, sawmill, dry kiln, molding department and showroom/gift shop General natural community overview Northern hardwood swamps are deciduous forested wetlands that occur along lakes, streams, or in insular basins in poorly drained morainal landscapes. Species composition within hardwood-conifer swamps exhibits considerable variation across the state. In addition, deer browse reduces frequency and cover of understory shrubs and herbs, altering structure of all strata and producing a cascade of effects extending to pollinators of affected plant species. Hardwood-conifer swamp is typically associated with headwater streams or shallow kettle depressions in poorly drained outwash channels or in depressions on outwash plains, medium- to coarse-textured end moraines, and glacial lakeplains. For information about plant species, visit the Michigan Flora website. Wilton, H.D. Check flight prices and hotel availability for your visit.

Leopold. There are 219 Swamps in Michigan. Bottomland hardwood forests are river swamps. Maintaining mature, senescent, and dead canopy trees within hardwood-conifer swamp stands ensures a continuing source of the large-diameter coarse woody debris important for seedling germination and survival. Conservation of wetlands requires management and protection of adjacent upland communities aimed at maintaining hydrology, minimizing inputs of nutrient-rich runoff, and protecting and managing habitat for animal species that require both upland and wetland habitats.
