Preface to CarboMont Special Feature

Mountain regions are important sources of water (Mountain Agenda 1998), centers of biodiversity (Körner and Spehn 2002) and areas for recreation and tourism, but they are also highly sensitive to human (Cernusca and others 1999) and climate effects (Beniston 1994). Ongoing socio-economic changes have strongly influenced land use in mountain areas, resulting in patterns of intensification and abandonment that differ across Europe (Tappeiner and others 2003). During the last decade there have been considerable efforts to assess the contribution of different ecosystems to the global carbon cycle (Baldocchi 2008). There is already substantial information on the carbon sequestration of forest ecosystems (Valentini and others 2000); however, data on the carbon cycling of non-forest ecosystems are still underrepresented (Falge and others 2002). Grasslands cover about 40% of the global terrestrial ice-free surface, but their contribution to local and regional carbon fluxes remains uncertain...
