Cycling nutrients • Plants drive the ecosystem • Make the food • Photosynthesis • Plants retain the food they make Katherine Verbeke Pa Wetlands
Oxygen • Used for respiration by heterotrophs Katherine Verbeke Pa Wetlands
Plants • Move nutrients • Phosphorous • Nitrogen Katherine Verbeke Pa Wetlands
Buffer zones • Riparian barriers • Function as a sponge • Absorb Excess runoff • Slowly release it back to the environment Katherine Verbeke Pa Wetlands
Benefits • Help reduce flood damage to crops • Help control rate and volume of runoff in urban areas Katherine Verbeke Pa Wetlands
Protect coastlines from erosion • Roots of all wetland plants hold soil • Plants absorb the action and force of waves • Break up the flow of streams and river currents • Buffer storm surges Katherine Verbeke Pa Wetlands
Prevents • Hurricane damage • Tropical storm damage • To roads, houses and other structures Katherine Verbeke Pa Wetlands
Pollution control • #1 pollutant in Pa (by volume) sediment • Wetlands slow the river • Sediment is deposited • Improves water quality for wildlife Katherine Verbeke Pa Wetlands
