Wetland restoration is a relatively new area of research that we are actively pursuing. Plant and soil specimens are used to recreate the characteristics of the habitat over time. Identification allows scientists to determine the story behind the soil: how it formed, how it behaves in different scenarios, and how valuable it may be to certain plants and animals. Wetland soils differ from bottom sediments, however, in that they are usually heavily vegetated and often are in contact with the atmosphere, thus facilitating the direct release to the atmosphere of greenhouse gases such as methane and carbon dioxide (e.g., Fechner-Levy and Hemond, 1996). Plants and Soils in Walnut Wetlands - North Carolina State University (Grades 8+) This site is part of a project done for Wetland Soils course at NCSU.

Wetland restoration is a relatively new area of research that we are actively pursuing. Plant and soil specimens are used to recreate the characteristics of the habitat over time. Identification allows scientists to determine the story behind the soil: how it formed, how it behaves in different scenarios, and how valuable it may be to certain plants and animals. Wetland soils differ from bottom sediments, however, in that they are usually heavily vegetated and often are in contact with the atmosphere, thus facilitating the direct release to the atmosphere of greenhouse gases such as methane and carbon dioxide (e.g., Fechner-Levy and Hemond, 1996). Plants and Soils in Walnut Wetlands - North Carolina State University (Grades 8+) This site is part of a project done for Wetland Soils course at NCSU.

Wetland restoration is a relatively new area of research that we are actively pursuing. Plant and soil specimens are used to recreate the characteristics of the habitat over time. Identification allows scientists to determine the story behind the soil: how it formed, how it behaves in different scenarios, and how valuable it may be to certain plants and animals. Wetland soils differ from bottom sediments, however, in that they are usually heavily vegetated and often are in contact with the atmosphere, thus facilitating the direct release to the atmosphere of greenhouse gases such as methane and carbon dioxide (e.g., Fechner-Levy and Hemond, 1996). Plants and Soils in Walnut Wetlands - North Carolina State University (Grades 8+) This site is part of a project done for Wetland Soils course at NCSU.
