  • 10 messages for 2010 — Forest ecosystems

    Key messages Forests cover a large part of Europe but the distribution of such ecosystems varies significantly across the continent. They fulfil multiple functions for society, providing economic, social and environmental benefits, including serving as a key reservoir of biodiversity. Old growth natural and semi-natural forests are the most valuable forest type in terms ...

  • Biogeochemical response of a northeastern forest ecosystem to biosolids amendments

    Received for publication September 22, 2007. In the northeastern United States interest in the use of biosolids on forest lands is growing due to the prevalence of extensive forests and market incentives for waste disposal, yet much of the regulatory framework for biosolids land application is based on agronomic practice. This study evaluated the response of soils in a young (~20 yr old) ...

  • European forests - ecosystem conditions and sustainable use

    Despite political commitment, Europe is struggling to halt the loss of biodiversity by 2010. Forests, as the hosts of much of the biological diversity in Europe, are vital to this debate. Any initiative designed to halt the biodiversity loss in Europe must take forests into account. Forests and biodiversity: are we doing better? Forests today cover 33 % of the land area of the countries of the ...

  • Mercury in litterfall and upper soil horizons in forested ecosystems in Vermont, USA

    Mercury (Hg) is an atmospheric pollutant that, in forest ecosystems, accumulates in foliage and upper soil horizons. The authors measured soil and litterfall Hg at 15 forest sites (northern hardwood to mixed hardwood/conifer) throughout Vermont, USA, to examine variation among tree species, forest type, and soils. Differences were found among the 12 tree species sampled from at least two sites, ...

  • The potentiation of zinc toxicity by soil moisture in a boreal forest ecosystem

    Northern boreal forests often experience forest dieback as a result of metal ore mining and smelting. The common solution is to lime the soil which increases pH, reducing metal toxicity and encouraging recovery. However, in certain situations, such as Flin Flon, Manitoba, Canada, liming has only yielded moderate benefits with some locations responding well to liming and other locations, not at ...

  • Mass balance of Cadmium in two contrasting oak forest ecosystems

    The mass balance of cadmium in forest ecosystems was parameterized. Soil pH is the main variable controlling retention of Cd in the soil and, hence, determines whether Cd is leached from the system or not. However the extent to which root uptake and biomass accumulation of Cd, or the return of Cd to the soil as internal cycling, influences forest Cd balances is unknown. Also unknown is whether ...

  • Assessment of Environmental Water Demands (EWD) of Forests for Two Distinct Indian Ecosystems

    Abstract  Sustainable use of water and land resources requires that these scarce resources be appropriately allocated among various competing human activities. Worldwide, there is a realization now that sustainable river basin management should be accorded the highest priority, because it deals not only with technical, but also with ecological and socioeconomic aspects, and thus calls for a ...


  • An economic analysis of ecosystem restoration concession policy in Indonesia: a new strategy for sustainable forest management?

    To tackle the high rate of deforestation in Indonesia's production forests, a new type of licence was introduced in 2004 known as an Ecosystem Restoration Concession (ERC) or IUPHHK–RE by the Indonesian Government. For the first time, production forests could be managed for the purpose of restoration instead of logging. At the same time, however, the economic feasibility of ecosystem restoration ...

  • “Novel ecosystems” are a Trojan horse for conservation

    They provide a license to trash nature if they provide ecosystem services Conservation biology and restoration ecology have been roiled by a bandwagon termed “novel ecosystems,” heralded as the “new ecological world order” in a manifesto published in 2006 by several ecologists headed by Richard Hobbs, then editor in chief of the journal ...

  • 10 messages for 2010 — mountain ecosystems

    Key messages - European mountain regions provide essential ecosystem services for lowlands and host a great diversity of habitats and species, many adapted to specific extreme climatic conditions. - Mountain ecosystems are fragile and vulnerable, and face severe threats from land abandonment, intensifying agriculture, impacts of infrastructure development, unsustainable exploitation and climate ...

  • Bringing ecosystem markets to scale in the Southern United States

    For the most part, Ecosystem Markets still linger in the early stages of development. There is much more theoretical work to be done to set up environmental credit markets, including carbon offsets and payments for watershed services. But more pilot projects can also help these markets evolve and show how they might work in the real world. Development pressures in the U.S. South often mean ...

  • Refocusing on nature: Holistic assessment of ecosystem services

    The benefits people obtain from ecosystems vary from direct benefits that are easily monetized (e.g., timber) to indirect benefits that are not easily monetized (e.g., maintenance of water quality). Commonly, there is wide variation among individuals in the values placed on ecosystem benefits or services. The lack of consensus both in identifying ecosystem services and in valuing them with ...

  • Community involvement with forest management can boost biodiversity

    Forests can act as carbon sinks and help counteract climate change. A study of forestry practices in India shows that involving local communities in conservation efforts can boost the biodiversity and stability of forest ecosystems. Community-based forest management policies may therefore represent valid carbon mitigation strategies. The EU aims to reduce its greenhouse gas emissions by more than ...

  • The Role of Eucalyptus Globulus Forest and Products in Carbon Sequestration

    Abstract This study is a contribution to the ongoing debate about the selection of the approach for carbon accounting in wood products to be used, in the future, in the national greenhouse gas inventories under the UNFCCC (United Nations Framework Convention on Climate Change). Two accounting approaches are used in this analysis: the stock-change approach and the atmospheric-flow approach. ...

  • Significance of Landscape Age, Uplift, and Weathering Rates to Ecosystem Development

    The combined roles of chemical and physical weathering have profound effects on the development of terrestrial ecosystems. Landscapes which are tectonically active are rapidly denudated and continually produce nutrient solutes from fresh bedrock. The chemical weathering yields are related to climate, but also to geologic factors such as uplift rates. Long-term nutrient production and the phase of ...

  • Ecosystem Management across Ownerships: the Potential for Collision with Antitrust Laws

    Abstract: Cross-boundary ecosystem management is increasingly being advocated to address large-scale ecological issues on forested landscapes. Such management requires information about the age, composition, and distribution of trees and other vegetation in addition to the ability to coordinate management over large areas. In the United States, the forest industry owns and ...


  • Guidelines for identifying business risks and opportunities arising from ecosystem change

    Ecosystems provide businesses with numerous benefits or “ecosystem services.” Forests supply timber and wood fiber, purify water, regulate climate, and yield genetic resources. River systems provide freshwater, power, and recreation. Coastal wetlands filter waste, mitigate floods, and serve as nurseries for commercial fisheries. However, human activities are rapidly degrading these and other ...

  • Preliminary review of adaptation options for climate-sensitive ecosystems and resources

    The US Government’s Climate Change Science Program (CCSP) is responsible for providing the best science-based knowledge possible to inform management of the risks and opportunities associated with changes in the climate and related environmental systems. To support its mission, the CCSP has commissioned 21 “synthesis and assessment products” (SAPs) to advance decision-making on climate ...

  • Green Urban Infrastructure: Assessing Potential Ecosystem Services in Urban Cities

    Cities all over the world are currently experiencing climate change caused by rapidly increasing atmospheric greenhouse gases (GHGs). Fortunately, cities may mitigate GHG concentrations by incorporating vegetation into green urban infrastructure (GUI) to develop parks, green roofs, waterways, and other structures. For example, plants sequester carbon (C) by removing atmospheric ...
