Global Forest Resources Assessments

Global Ecological Zones (GEZ) mapping

Expert consultations to FRA 2000 provided a mandate to incorporate biodiversity indicators into the assessment and as a response FAO developed the first Global Ecological Zones (GEZ) classification and maps to enable the presentation of some of the FAO forest statistics to be shown by a set of classes that have some ecological meaning and more generally understood as broad forest types (e.g. tropical rain forests, boreal forests etc.).

Due to recent developments in remote sensing and many new spatial products and data sets related to climate and land cover, an update to the GEZ 2000 map was commissioned as part of the FRA activities and carried out during 2011. The work included contributions from many scientists and partner organizations, and resulted in an updated GEZ 2010 map and a technical report describing in detail the process and the changes made.
