Inland Wetlands Alternate Names: Marshes, bogs, swamps Presented by: VC and AMB
land whose soil is saturated with moisture • common on floodplains along rivers and streams • in isolated depressions surrounded by dry land • along the margins of lakes and ponds • in other low-lying areas Location
No characteristic climate • Temperatures vary greatly depending on the location of the wetland. • Amount of rainfall a wetland receives depends upon its location • Factors: plant community, soil, longitude and latitude Climate
spongy tissues, called aerenchyma • adventitious roots above the anoxic zone • prop roots with pores • arrowhead common cattail yellow lotus Plant Adaptation
specialized gills or other organs to increase the uptake of oxygen from water or to use it more efficiently • build dams that may flood large areas • dig holes that retain water during the dry season • Spider crab North American beaver American alligator Animal Adaptation
Soil – poorly drained, alluvial and floodplain, low pH • Good water quality and replenishes goundwater • Nutrients – carbon, nitrogen, oxygen, and phosphorus, sulfur • Origin: Plants and runoff water Soil and Chemical Cycling
filtering capabilities for intercepting surface water runoff • maintain stream flow during dry periods and replenish groundwater • lowers flood heights and reduces erosion • control floods and prevents water-logging of crops • many animals and plants depend on wetlands for survival Economic Value
hydrologic alterations in wetland • ex. deposition of fill material for development • pollutants causing wetland degradation • ex. runoff from urban, agricultural, silvicultural, and mining areas • impair wetland vegetation • ex. grazing by domestic animals Human Disturbance
