  World Database on Protected Areas (WDPA) Data Standards »

  This document provides information about the standards and data held within the World Database on Protected Areas (WDPA). The WDPA Data Standards specify a common set of information that data providers are asked to provide when submitting data to the WDPA. These ensure that the most vital information is collected and that the data is supplied in a common format that is globally interoperable. This document also provides detailed information on the type of information and each attribute/field within the WDPA.

  The Challenge of Measuring Global Change in Wild Nature: Are Things Getting Better or Worse? »

  We briefly review recent global trends in habitat area in as many broadly-defined natural habitats as possible, and in indices of animal populations characteristic of those habitats. The information available indicates continuing declines in habitat area and species, but those data are extremely sparse.

  To provide a global context for a discussion of mountain forests, it is first necessary to define the locations and types of mountain forests, and this in turn requires a definition of mountains or mountain areas. Altitude and slope and the environmental gradients they generate are key components of such a definition, but their combination is problematic. Simple altitude thresholds both exclude older and lower mountain systems and include areas of relatively high elevation that have little topographic relief and few environmental gradients. Using slope as a criterion on its own or in combination with altitude can resolve the latter problem, but not the former. The mountains dataset shows the location of mountain land estimated from a digital elevation model using criteria based on elevation alone (the upper three classes: > 2 500 metres) and at lower elevation, on a combination of elevation, slope and local elevation range. This is an update of the Mountain's of the World 2000 and was produced for the UNEP-WCMC publication Mountain Watch, 2002.

  The mountains dataset has been overlayed with a global data set on percent tree cover taken from MODIS 1-km resolution percent tree cover data, courtesy of University of Maryland Global Land Cover Facility. Species richness, density and forest height tend to reduce with increasing altitude; the boundary between forest vegetation and more open ground cover at higher elevation 'the treeline' is an ecological marker signifying the transition to more extreme climatic conditions.

  Uncertainty in predictions of extinction risk/Effects of changes in climate and land use/Climate change and extinction risk (reply) »

  The number of environmental variables used during modelling could affect the outcome, but we found no correlation between these and our estimates of extinction risk in global samples. Although further investigation is needed, it is unlikely to result in substantially reduced estimates of extinction. Anthropogenic climate change seems set to generate very large numbers of species-level extinctions.

  This dataset was prepared by IUCN as a contribution to the UNESCO MAB Programme.
  The main purpose of the work was to devise a satisfactory classification of the world's biotic areas for purposes of conservation. It is the fourth attempt in a series of revisions, updating the previous three works written by Dasmann.
  The logic behind the system was that the plant and animal world occurs within
  the biosphere of the Earth in the form of an intertwined network of individuals,
  populations and interacting systems. To be able to view them in a systematic way, the biologist may use the following approaches:
  Taxonomic order, Ecological order, Phylogenetic order (origins and history).
  Biogeographic order - grouping the above entities on a geographic basis.

  To define geographic units for conservation purposes the following were considered:
  (a) the distribution of species and (b) the distribution of ecosystem units. The
  result was a system serving both aims, a hierarchical system of geographical areas which would give a framework for conserving species as well as ecologic areas.
  These hierarchical Biogeographical entities were named Realms, Biomes and Provinces.

  The first subdivision, the Realm, used the phylogenetic subdivisions of the world, unifying those for flora and fauna. It is a continent or sub-continent-sized area
  with unifying features of geography and flora/fauna/vegetation. Eight Realms were distinguished. The second division is the Biome. These were not the same as the
  major vegetation formations of the world (see UNESCO, 1973), but combine the features of a major vegetation type with climate. There are 14 of these. These
  were largely based on the work of Dasmann. The third, most detailed, subdivision was the Province, delimited on a faunal, floral and ecological basis. There are
  186 of these.

  1997 United Nations List of Protected Areas »

  The United Nations List of Protected Areas is an essential reference document for all who want to understand the progress made in responding to the challenges of biodiversity loss and other environmental threats around the world. It is a record of extraordinary human achievement over 125 years - a commitment by nations, peoples, groups and individuals to safeguard areas of land and sea from destruction. Protected areas represent human ideals at their best - they express a long term vision and a broad sense of responsibility towards people and nature.

  This version of the list is the twelfth in a series, each recording steady expansion in the total area protected. There are now some 12,754 areas in the UN List, covering almost 8% of the land surface of the world (a far smaller proportion of the oceans is protected). Compared to the previous, 1993 edition of the of the UN List, this report includes 2,933 more sites covering 3.9 million more square kilometres. At the end of the century it can be said that practically every country has protected areas; some have a very sophisticated network of sites.

  The purpose of the work, which began in 1976, was to show how the national forests of the United States fit within the global ecoregional scheme. In this system an ecoregion is defined as any large portion of the Earth's surface over which the ecosystems have characteristics in common. There are three levels in this classification system, the Domains, the Divisions and the Provinces.

  Ecoregions of the continents are based on macroclimate (i.e., the climate that lies just beyond the local modifying irregularities of landform and vegetation). The theory behind the approach is that macroclimates are among the most significant factors affecting the distribution of life on Earth. As the macroclimate changes, the other components of the ecosystem change in response. Macroclimates influence soil formation and help shape surface topography, as well as affecting the suitability for human habitation.

  Four Domains were defined: Polar, Humid temperate, Humid tropical and Dry. The combination of temperature and rainfall to indicate major climatic zones was based on Köppen and Trewartha's work, where dry climates were treated as a separate entity from Tropical humid and Temperate humid. However, the Köppen system defines an addtional "Subtropical" division at this level.

  The next level in the Bailey system is the Divisions, and these are also climate - based, for example in the Humid temperate Domain there is Hot continental, Warm continental, Subtropical, Marine, Prairie and Mediterranean, all with Mountain variants (i.e., a total of 12 Divisions in this Domain). There are a total of 30 of these.

  The third and last level are the Provinces, which are based on physiognomy of vegetation, modified by climate. For example, the Forest-Meadow of Eastern Oceanic (Monsoon climate). There are a total of 98 of these subdivisions.

  The global map has been digitised and converted to a geographic (lat/long) projection by the WCMC, Cambridge, UK. It is also available on CD from NOAAs National Geophysical Data Center in Boulder, Colorado as part of their Global Ecosystem Database Project. http://www.ngdc.noaa.gov/Store/.

  La délimitation des montagnes européennes (Delineating Europe's mountains) »

  As the importance of mountain spaces is more widely recogised, it seems necessary to establish a coherent definition of these spaces. The UNEP World Conservation Monitoring Centre (UNEP-WCMC) proposed the first global delineation in 2000. However, certain European countries have used national definitions of mountain spaces since the 1950s. Within the framework of social and economic integration policies at the heart of the European Union, an agreed delineation of European mountain spaces has been established, based on the definition proposed by UNEP-WCMC. The process of adaptation of the global definition to the European context is described, as well as the results for 29 European countries.

  Distribution and conservation status of forest bamboo biodiversity in the Asia-Pacific Region »

  Although Asian bamboo species constitute a non-timber forest product of major cultural and economic importance, no detailed regional assessment of their distribution patterns has previously been made. To assess the potential of the existing bamboo species distribution data for production of regional mapping tools for planning the conservation of forest-based biodiversity, data on bamboo distribution and forest cover were combined. Over 1000 bamboo species from 60 genera of woody bamboos were incorporated, allowing the mapping of individual species or groups of species and genera, along with potential species richness and biodiversity hotspots. Over 6.3 million km2 of Asian forest potentially contains bamboo, with highest densities indicated from northeastern India through Burma to southern China, and through Sumatra to Borneo. The highest figures for potential species richness (144 spp per square km) were recorded in forests of south China, including Hainan Island. Despite substantial inadequacies and inconsistencies in knowledge of the taxonomy and distribution of bamboo species, this approach may provide a valuable tool for planning in situ conservation of forest biodiversity.
