Wetland Functions and Values: Erosion Control

wetlands along the shore of moving waterVegetated wetlands along the shores of lakes and rivers can protect against erosion caused by waves along the shorelines during floods and storms. Wetland plants are important because they can absorb much of the energy of the surface waters and bind soil and deposited sediments in their dense root systems.
      

Wetland Functions and Values: Surface and Ground Water Protection

Pollutants include soil particles, fertilizers, pesticides, grease and oil from cars and trucks, and road salts. Wetlands can improve water quality by removing pollutants from surface waters.

Restore

Wetland restoration is the process of returning a degraded wetland to an approximation of its pre-disturbance condition. The United States lost over half of its wetlands since European colonization in the early 1600s, and Vermont lost as much as 35 percent. Until recently, wetlands were seen as obstacles to development, agriculture, and travel, and were systematically drained and altered.

Conserve and Protect

Wetland conservation and protection is aimed at preventing the loss of wetlands and the functions and values they provide. The United States lost over half of its wetlands since European colonization in the early 1600s, and Vermont lost as much as 35 percent. Until recently, wetlands were seen as obstacles to development, agriculture, and travel, and were systematically drained and altered. Conversion of wetlands was accepted practice as recently as the 1950s, and was even incentivized by government policies.

Hydrophytic Vegetation

Wetland plants, or hydrophytic "water loving" vegetation, are those plants which have adapted to growing in the low-oxygen (anaerobic) conditions associated with prolonged saturation or flooding. These plants have adapted to anaerobic soil conditions by evolving alternative methods of collecting oxygen such as the hypertrophied lenticels in the bark of speckled alder; the hollow stems of rush and grass species; and the air filled cells (aerenchyma) in the roots of cattails.
