    Study Notes

    Wetland Ecology

    • A hydrophyte is a plant adapted to living in water or wet soil.

    Soil Characteristics

    • Hydric soil is characterized by low oxygen levels, high water tables, and limited drainage.

    Wetland Ecosystems

    • SAVs (Submerged Aquatic Vegetation) are plants that grow underwater in wetland ecosystems.

    Plant Adaptations

    • A pneumatophore is a specialized root system that allows plants to breathe in oxygen-poor environments.

    Atmospheric Measurements

    • Relative humidity is the measure of the moisture content or humidity in the air, expressed as a percentage.
    • Atmospheric pressure is measured using a barometer.
    • Conductivity is the measure of the ability to conduct electrical currents.

    Wetland Processes

    • Evapotranspiration is the combined process of water vapor being released into the atmosphere through evaporation and transpiration.
    • Transpiration is the release of water vapor by plants.

    Wetland Types

    • The most common wetland ecological type in Maryland is freshwater wetlands.
    • The western region of Maryland contains the greatest acres of forested wetlands.

    Peat Formation

    • Peat is formed through the accumulation of partially decayed plant matter in oxygen-poor conditions.

    Wetland Indicators

    • Three indicators that define a wetland are:
      • Hydrophytic vegetation
      • Hydric soil
      • Wetland hydrology
    • Six indicators of wetland hydrology are:
      • Flood frequency
      • Water table depth
      • Soil saturation
      • Surface water connection
      • Water chemistry
      • Sediment composition

    Ecological Systems

    • The five ecological systems (or water regimes) in which wetlands may be found in Maryland are:
      • Freshwater
      • Brackish
      • Saltwater
      • Tidal
      • Non-tidal
