Preliminary Assessment Of Client Interest In And Needs Of The New England Environmental Finance Center, New England Environmental Finance Center, University Of Southern Maine

Planning

The New England Environmental Finance Center (NE/EFC) has been conceived as a knowledge-based clearinghouse, training, and change-agent program aimed at helping EPA's constituencies find financially successful approaches to environmental improvements. The NE/EFC will develop approaches to needs of particular priority in New England and potentially useful throughout the nation; share such approaches through the EFC national network; and help make tools from that network accessible throughout New England. In 1999 we began exploring with potential users how this ninth of the nation's EFCs might best address the region's needs. The assessment continued through the Muskie School's EFC proposal to EPA …

Faculty Works: CERCOM

Floyd Bennett Field (FBF), 579 ha in extent, is a division of Gateway National Recreation Area. It is the site of a former airfield, constructed by filling salt marshes with dredged materials. Except for the portion known locally as the “North Forty,” all sections of FBF have been cut over to maintain low vegetation. A grassland management plan (GRAMP) for 165 ha was initiated in 1986, to maintain habitats for open-country birds. Over the next few years, encroaching woody vegetation was removed manually and mechanically from the management area. Since then, it has been maintained as a grassland and receives …

Environmental Finance Charette, Hyannis Park On Lewis Bay: A Case Study, New England Environmental Finance Center, Environmental Finance Center Of University Of Maryland

Water

The town of Yarmouth currently has a $30 million septic sludge treatment plant and transport lines in place. The vast majority of the dwellings and businesses in the Hyannis Park area are on septic systems that are viable and Title 5 compliant, regardless of age. Conventional, "non-failing" septic systems, however, were never intended to remove form their effluent nutrients such as nitrogen. These have become recognized as an environmental threat only as our understanding of the impacts of excess nutrients on ecosystems has increased in recent decades.

Western Rangeland Noxious Weeds: Collecting, Sharing And Using Information, U.S. Department Of Interior, U.S. Department Of Agriculture, Riley Memorial Foundation

Survey Of Aquatic Plants In Corps Of Engineers Reservoirs, Kimberly D. Walker, Mark D. Sytsma

Center for Lakes and Reservoirs Publications and Presentations

A survey of aquatic plants in a selected Corps of Engineers reservoirs in Oregon was conducted. Cottage Grove, Dorena, Fern Ridge, Dexter and Willow Creek Reservoirs contained abundant aquatic plants. Potamogeton pectinatus and Potamogeton epihydrous were the most common native plant species. Myriophyllum aquaticum and Potamogeton crispus were the most widespread nonnative plants. Species richness in the reservoirs was correlated with trophic status and basin morphology. Shallow reservoirs that included extensive areas of nutrient-rich sediments that were historic flood plain soils supported the greatest biomass and number of species. Mesotrophic reservoirs had lower species diversity. Oligotrophic reservoirs with steep basin …

Assessing Interconnections Between Wilderness And Adjacent Lands: The Grand Staircase-Escalante National Monument, Utah, Janice L. Thomson, Dawn A. Hartley, Gregory H. Aplet, Peter A. Morton, Usda Forest Service Proceedings

All U.S. Government Documents (Utah Regional Depository)

Wilderness managers have traditionally managed wilderness lands based on the ecological and social content of wilderness areas. The authors propose a framework to systematically account for the biophysical, socioeconomic, and wildness characteristics of the broader landscape context. The method was applied to the proposed wilderness lands of the Grand Staircase-Escalante National Monument in southern Utah. The results illustrate patterns of interdependencies across the landscape. Spatial data demonstrate links between the integrity of proposed wilderness lands and the management of adjacent land units, and links between the economic health of local communities and the management of proposed wilderness and adjacent federal …

Annual Update Of Tampa Bay Chlorophyll-A Concentrations 2000, J. O.R. Johansson

Reports

The amount of phytoplankton present in Tampa Bay waters can be estimated from measurements of the green plant pigment chlorophyll-a. Phytoplankton is one of several major forms of plants that exist in Tampa Bay and most other estuaries. Other major plant types are submerged seagrass, macro-algae and benthic micro-algae. The different plants can be viewed as being in competition with each other for required resources, such as light and nutrients. Studies conducted in urbanized estuaries have shown that excessive loading of nitrogen generally is accompanied by an increase of phytoplankton and macro-algae, including epiphytic and drift macro-algae, and by a …
