Global Forest Resources Assessment 2000 (FRA 2000)FRA 2000 is the most comprehensive and technologically advanced assessment in FAO's 50-year history. FRA 2000 depended on the active participation of partners and member countries around the world. The thematic content is broader than ever before, covering forest area status and change, biological diversity, timber volume and forest biomass, non-wood forest products, trees outside the forest, forest fires and other topical issues. For the first time, comparable trend information on tropical deforestation from two successive assessment periods has been obtained through the use of statistical sampling and satellite remote sensing. FRA 2000 was the first assessment to use a homogeneous set of definitions gobally. To counteract the increasing flow of often recycled information, FRA 2000 presented the results with full transparency and reference to source data.
FRA 2000 stretched over the period 1996-2002 and included all countries and territories. The work followed a strategic plan for FRA 2000 based on the recommendations of a 1996 expert consultation (Kotka III). The plan was formally endorsed by the FAO Committee on Forestry (COFO) in 1997. Implementation of the work on data compilation was carried out from 1998-2000. In 2001 the data was validated with the national authorities before publishing the results of FRA 2000 on the FAO Web site and as FRA 2000 Main Report (FAO Forestry paper 140). The final phase of the FRA 2000 process was the review atKotka IVexpert consultation in July 2002.
FRA 2000 involved data compilation at the national, regional and global level as described below.
- National level. FRA 2000 describes the state of the worlds forest by the year 2000 and employs a homogenous set of definitions for all countries and territories. FRA 2000 national level area data is based on existing, documented forest inventory data and was compiled in cooperation with and validated by the national authorities. Data from these compilations is available as country profiles or in summarized format via the FRA 2000 global tables.
- Regional level. FRA 2000 includes a remote-sensing survey covering about 10 percent of the forest area in the tropical zone. The remote-sensing survey interprets land use at three points in time (around 1980, 1990 and 2000) allowing for studies of forest cover change processes in the tropics during the two decades 1980-2000. For the three tropical regions, the survey provides regional estimates of forest area and land use changes. These estimates are independent of the national assessments of forest resources based on country submissions.
- Global level. New global maps of forest cover and ecological zones have been produced for FRA 2000 by using low resolution satelite imagery. The global mapping has not been used for estimating forest area and forest area change but to supplement the core information related to conventional forest inventories based on country submissions among others for producing estimates of proportional distribution of forests by ecological zone.
For temperate and boreal forests, detailed information is provided in the 2000 Geneva Timber and Forest Study Paper No. 17, by UN-ECE, Geneva.Main Report - Forest Resources of Europe, CIS, North America, Australia, Japan and New Zealand.
