  • In spite of the fact that the area of Sagami Bay occupies only 0.05% of the total area of Japanese waters, the total species richness is 16.5% of the total Japanese species richness. This suggests high species richness due to the array of habitats present in Sagami Bay. The high species diversity of Sagami Bay has been recognized previously, and one of the proposed reasons for this degree of diversity is the influence of cold-water masses derived from the Oyashio Current, as well as tropical or subtropical water masses derived from the Kuroshio Current. Sagami Bay’s high reported diversity probably contains bias, because marine biologists have historically paid more attention to Sagami Bay.

  • Islands are unique place to be characterized as a long-term monitoring site, sustaining communities and preserved high rate of endemism. For not having the typical impacts of increasing urbanization in the coastal zone, it becomes possible to reliably identify the appropriate sources of impacts (such as overfishing), and the direct consequences on the system. This statement is difficult to precisely on the coast where the synergism disorders does not isolate each process. Still being the islands of control ICMBio with some protection status (Fernando de Noronha = National Park; Atol das Rocas = Biological Reserve), or with ongoing research programs with the logistical support of the Navy of Brazil and funding CNPQ (Archipelago St. Peter and St. Paul and Trindade island), management and conservation rules can be more efficiently deployed without generating conflicts with the various groups of users of the areas, which is a common situation when it comes to coastal systems where 50% of the population live.

  • The site is located in the Southern Carpathians (Romania). The predominant ecosystems are grasslands located above tree line, dominated by Carex curvula, Juncus trifidus (alpine zone) and Festuca airoides, Nardus stricta (subalpine zone). The site consists of monitoring points in subalpine and alpine meadows in the Bâlea-Paltinul area.

  • The Woodland Restoration Plot Network is located in the Cumberland Plain, Western Sydney, NSW, Australia with the objective to develop robust methods for evaluating the success of native woodland restoration on retired agricultural land and apply them to a major restoration project of an endangered ecological community. The plot network aims to determine whether the composition and structure of restoration plantings undertaken between 1992 and 2002 are on a trajectory from abandoned exotic pasture towards comparatively undisturbed remnant vegetation. The data gathered will inform future restoration efforts. Between 2012 and 2018 the Woodland Restoration Plot Network was is a member of Long Term Ecological Research Network (LTERN), Australia, a facility of the Australian Government's Terrestrial Ecosystem Research Network (TERN).

  • The Victorian Alpine Plot Network is located in Victoria’s Bogong High Plains and other high plains and mountain summits. Temporal visits generally range from every 3 to 10 years with some plots are surveyed annually during initial monitoring. Between 2012 and 2018 the Victorian Alpine Plot Network was a member of Long Term Ecological Research Network (LTERN), Australia, a facility of the Australian Government's Terrestrial Ecosystem Research Network (TERN).

  • The site is composed by a set of Atlantic Forest fragments and restoration sites scattered in an agricultural landscape in north of Parana state, south Brazil. The forest in this region is a seasonal semi-deciduous form of Atlantic Forest, which undergone strong conversion rates from 1940 to 1980 and presently has only 8% forest cover, distributed in a myriad of small fragments. Forest fragmentation, fertilizer and pesticide leakage from agricultural fields and urbanization are the main regional drivers of environmental change. In each sub-site (forest fragment or restoration site) we are sampling flora, fauna and ecosystem attributes (forest biomass, litter fall, litter decomposition etc). The site is maintained by Londrina State University

  • The Jonkershoek Valley site is located in a mountain catchment in the Cape Floristic Region and is the source of the Eerste River. The site was originally dominated by Boland Granite fynbos and Kogelberg Sandstone fynbos with patches of afrotemperate forest. From the 1930s, first order catchment experiments were established in the valley by the Jonkershoek Forestry Research Centre (JFRC) under the auspices of the South African Forestry Research Institute (SAFRI). The catchments were sequentially planted to pine species. Gauged weirs were built in the experimental catchments. Long term records exist for five gauged pine planted catchments and one natural fynbos catchment. The Swartboskloof catchment, located in the Jonkershoek valley, was the site of fire experiments in the 1970s and 80s.

  • The majority of research is conducted within the US Forest Service Coweeta Hydrologic Laboratory located in the Nantahala Mountain Range of western North Carolina, USA, within the Blue Ridge Physiographic Province. The site is part of the Upper Little Tennessee River Watershed Basin.

  • The site is located in the Southern Carpathians (Romania). The predominant ecosystems are grasslands located above tree line, dominated by Carex curvula, Juncus trifidus (alpine zone) and Festuca airoides, Nardus stricta, Festuca nigrescens (subalpine zone). The site consists of monitoring points in subalpine and alpine meadows.
