Temperature and water-level effects on greenhouse gas fluxes from black ash (Fraxinus nigra) wetland soils in the Upper Great Lakes region, USA

Forested black ash (Fraxinus nigra) wetlands are an important economic, cultural, and ecological resource in the northern Great Lake States, USA, and are threatened by the invasive insect, emerald ash borer (Agrilus planipennis Fairmmaire [EAB]). These wetlands are likely to experience higher water tables and warmer temperatures if they are impacted by large-scale ash mortality and other global ch...

Locating delineated wetland boundaries in coastal South Carolina using global positioning systems

A six-channel Global Positioning System was used to locate eleven points on wetland boundary lines. The latitude and longitude of these points were compared to locations obtained by a second order ground survey. Operating criteria and tree foliage coverage varied over a 19-month period of data collection (February 1992 to October 1993). Canopy coverage levels sampled within a hurricane impacted ar...

Carbon stock trends of baldcypress knees along climate gradients of the Mississippi River Alluvial Valley using allometric methods

Publication date: 1 April 2020Source: Forest Ecology and Management, Volume 461Author(s): Beth MiddletonAbstractCarbon stock trends of the knees of Taxodium distichum likely vary across climate gradients of the southeastern United States and contribute an unknown quantity of “teal” carbon to inland freshwater wetlands. Knee metrics (e.g., density, height, biomass) were measured in mixed T. dis...

In search of the wetland boundary

Implementation of Section 404 of the Federal Water Pollution Control Act of 1972 and the “swampbuster” provisions of the Food Security Act of 1985 require identification and delineation of wetlands in accordance with applicable statutes and regulations. While a considerable amount of work has gone into characterizing wetlands, very little has gone toward delineating the boundary between unregu...
