Aquatic Ecosystems Toolkit Module 2: The ANAE is a broad-scale, semi-hierarchical, attribute-based scheme, which provides a nationally consistent, flexible framework for classifying different aquatic ecosystems and habitats including rivers, floodplains, lakes, palustrine wetlands, estuaries and subterranean ecosystems. However, it is designed to be flexible for multiple uses, and may be used to inform national aquatic ecosystem mapping and inventory processes. The ANAE can also be used to build on and integrate with existing classification schemes.

Wetland soils are different then the soils found in dry lands. Wetland soils are called hyrdric soils because the spaces between each grain of soil is filled with water.

Wetland soils are anaerobic. Anaerobic means that the soil lacks oxygen. The color of wetland soils is usually dark brown to black due to the presense of mineral or organic matter. Wetland soils may also have a rotten egg smell due to the presense of sulfur.

Hydric Soil Wetland vegetation: Wetland plants have adaptations that allow them to live in an area that is saturated with water at various times in the year. Saltwater wetland plants have special adaptations that allow them to tolerate varying degress of salt.

Wetland plants are called hydrophytes. Major Wetland Functions and Values In the past wetlands have been viewed as wasted land. They have been viewed as swampy, bug infested waters. Wetlands were also blamed for causing diseases.

Malaria is an Italian word that means "bad air" because it was believed that the air of the swamps caused this terrible disease. For these reasons it became common practise to drain, fill, or build over many wetlands.

In the past hundred years America has lost half of her wetlands. Fortunately, scientists have realized that wetlands have tremendous value. The following message was given by President Jimmy Carter in The nation's coastal and inland wetlands are vital natural resources of critical importance to the people of this country.

Wetlands are areas of great natural productivity, hydrological utility, and environmental diversity, providing natural flood control, improved water quality, recharge of aquifiers, flow stabilization of streams and rivers, and habitat for fish and wildlife resources.

Wetlands contribute to the production of agricultural products and timber and provide recreational, scientific, and esthetic resources of national interest. Graphic Creations Publication The major functions and values of wetlands are the following: The habitats of numerous fish and wildlife are found in the wetlands.

A great percentage of fresh and salt water fish depend on the wetlands for spawning and nursery grounds. Over half on the migratory birds of the South spend at least part of their time en route in wetlands. Other animals spend some portion of their life in the wetlands for shelter, feeding, or water.

Rockfish The water in a wetland itself serves valuable purposes in the environment. The functions of water in a wetland are called hydrologic functions. Water in wetland serves the following functions: Buffers the effects of waves on the land 3.

Controls the amount of erosion 4. Stores water that refurbishes the groundwater 5. Discharges of groundwater into lakes, rivers, and streams during dry periods Wetlands play an important role in maintaining the quality of water of deep water habitats.

Wetlands carry out the following functions: This function is called sediment trapping. Much of the world's oxygen is produced in wetlands by microscopic plants called phytoplankton. The removal of nitrogen and phosphorous prevents the eutrophication of nearby ponds or lakes.Montpelier—Three unique Vermont wetlands are now being classified as ‘Class I’ wetlands, a designation that places extra protections on wetlands with exceptional ecological features.

The. 1 = Unique/outstanding wetland; B = Wetlands with a near equal proportion of open water to vegetative cover in dispersed patches in combination with a high diversity or mix of wetland subclasses; C = Wetlands greater than 10 acres in size and having 3 or more wetland classes, one of .

Introduction Module 2 is the Interim Australian National Aquatic Ecosystem (ANAE) Classification Framework. The ANAE is a broad-scale, semi-hierarchical, attribute-based scheme, which provides a nationally consistent, flexible framework for classifying different aquatic ecosystems and habitats including rivers, floodplains, lakes, palustrine wetlands, estuaries and.
