Ecosystem restoration design is a relatively new field of work that requires multi-disciplinary expertise in the natural sciences. Although the field is new, federal agencies and public institutions have spent several decades and millions of dollars researching the sciences and methods that underly restoration activities. However, many restoration practitioners are either unaware of this vast body of knowledge or simply do not know how to apply it to these newproject types.

The Adirondacks of New York have high levels of mercury (Hg) bioaccumulation as demonstrated by a region-wide fish consumption advisory for children and women who may become pregnant. The source of this Hg is atmospheric deposition that originates from regional, continental, and global emissions.

Managing forests on the Cumberland Plateau escarpment for select desirable species can be particularly onerous due to the high diversity of dominant tree species. We implemented 5 treatments to alter species composition and structure in an effort to favor Quercus and maintain its dominance in the stands. Treatments were shelterwood prescriptions that in the first stage retained a percentage of the basal area (100, 75, 50, 25 and 0 percent retentions). After 9 growing seasons, the residual trees in all but the 0 percent retention treatment were removed. We installed permanent vegetation...

The business of marketing, promotions in particular, has changed substantially during the past decade. Physical means of promotion (e.g., newspapers, magazines, radio, billboards) have seen a decline, and the use of social media as a marketing tool has increased significantly. While a number of studies regarding the use of social media among Fortune 500 companies have been conducted, very limited information is available regarding social media use in the US forest products industry. This article presents part one of a two-part series and addresses the first three of the following five...

Mercury (Hg) bioaccumulation factors (BAFs; ratios of Hg in fish [Hgfish] and water[Hgwater]) are used to develop Total Maximum Daily Load and water quality criteria for Hg-impaired waters. Protection of wildlife and human health depends directly on the accuracy of site-specific estimates of Hgfish and Hgwater and the predictability of the relation between these parameters.

Mercury (Hg) is the toxicant responsible for the most fish advisories across the United States, with 1.1 million river miles under advisory. The processes governing fate, transport, and transformation of mercury in streams and rivers are not well understood, in large part, because these systems are intimately linked with their surrounding watersheds and are often highly spatially variable.

The Edisto River is the longest and largest river system completely contained in South Carolina and is one of the longest free flowing blackwater rivers in the United States. The Edisto River basin also has fish-tissue mercury concentrations that are among the highest recorded in the United States. As part of an ongoing effort by the U.S. Geological Survey to expand the understanding of relations among hydrologic, geochemical, and ecological processes that affect fish-tissue mercury concentrations within the Edisto River basin, analyses and simulations of the hydrology of the Edisto River...

Cities are increasingly engaging in sustainability efforts and investment in green infrastructure, including large-scale urban tree planting campaigns. In this context, researchers and practitioners are working jointly to develop applicable knowledge for planning and managing the urban forest. This paper presents three case studies of knowledge co-production in the field of urban forestry in the United States. These cases were selected to span a range of geographic scales and topical scopes; all three are examples of urban researcher-practitioner networks in which the authors are situated...

Globally, municipalities are tackling climate adaptation and resilience planning. Urban green space has crucial biophysical buffering capacities, but also affects social interactions and human well-being. This paper considers the social dimension of urban green space, through an assessment focused on park use, function, and meanings, and compares results to categories of cultural ecosystem services. We develop a mixed-method approach for assessment of uses and social meanings of parkland and pilot this method in 2140 acres of parkland in waterfront neighborhoods surrounding New York City's...

McTier Creek is a small coastal plain watershed located in Aiken County, South Carolina. McTier Creek forms part of the headwaters for the Edisto River basin, which is noted for having some of the highest recorded fish-tissue mercury concentrations in the United States. A simple water-quality load model, TOPLOAD, which was developed for McTier Creek, utilizes a mass balance equation in conjunction with hydrologic simulations from the topography-based hydrological model - TOPMODEL. TOPLOAD is an effective tool for analyzing the relative flux contribution of the simulated surface and...
