Source data Title Forests 2000 by Major Ecological Domains Date 2001-07-01 Date type Creation: Date identifies when the resource was brought into existence Edition First edition. Presentation form Digital map: Map represented in raster or vector form Abstract Along with the core information on state and changes in forests, FRA 2000 is reporting on various ecological aspects of forests. Forest resources information will be reported by ecological zone, which will contribute to understanding the implications of forest change on (ecosystem) biological diversity and carbon-cycling processes. The 2000 global ecological zone map has been developed, building upon the FRA 1990 experience for the tropics and extending the coverage to include the temperate and boreal forests. A globally consistent classification has been adopted, based on the Koppen-Trewartha climate system in combination with natural vegetation characteristics. A total of 19 global ecological zones have been defined and mapped, ranging from the evergreen tropical rainforest zone to the boreal tundra woodland zone. A main principle of delineating the global ecological zones involved the aggregation or matching of available regional ecological or potential vegetation maps into the global framework. Purpose Main uses of the map include: a) reporting purposes, to provide baseline forest statistics by ecological zone; b) analysis and modelling purposes, i.e. assessment of forest-based biological diversity, both at ecosystem and species level, and biomass modelling.

The spatial data identified as FAO Core Datasets share the following characteristics: • Coarse resolution data, between 30 arcsec and 10 arcmin for the rasters, and between 1:1 million and 1:10 million scale for the vectors. • Related to a global, continental or regional level. Country data are not considered at this stage. • FAO as the main producer of the data or with publication rights as partner of a group that released the data. • Data release and access is unrestricted (public domain). • Primary (observed, mapped) and modeled data qualify.
