Ce document de synthèse de l’Atlas forestier interactif du Cameroun(V3.0) fournit au lecteur des informations sur les affectations et lestypes d’occupation des terres dans le Domaine Forestier Nationaljusqu’au mois de juin 2011. Il donne également un aperçu sur lestendances récentes de l’évolution des forêts de production, ainsique des développements récents dans le domaine de la foresteriecommunautaire. Il offre également les données actualisées sur lesaires protégées et le réseau routier public et privé, et donne de façonsubsidiaire des informations préliminaires sur les concessionsminières susceptibles d’empiéter sur le domaine forestier. En fin, cerapport met en exergue des exemples pratiques d’utilisation de l’Atlaset donne un aperçu de ses orientations et applications futures.

This data set, created by the GLAD (Global Land Analysis & Discovery) lab at the University of Maryland and supported by Global Forest Watch, is the first Landsat-based alert system for tree cover loss. While most existing loss alert products use 250-meter resolution MODIS imagery, these alerts have a 30-meter resolution and thus can detect loss at a much finer spatial scale. The alerts are currently operational for select countries in the Amazon, Congo Basin, and Southeast Asia, and will eventually be expanded to the rest of the humid tropics.New Landsat 7 and 8 images are downloaded as they are posted online at USGS EROS, assessed for cloud cover or poor data quality, and compared to the three previous years of Landsat-derived metrics (including ranks, means, and regressions of red, infrared and shortwave bands, and ranks of NDVI, NBR, and NDWI). The metrics and the latest Landsat image are run through seven decision trees to calculate a median probability of forest disturbance. Pixels with probability >50% are reported as tree cover loss alerts. For more information on methodology, see the paper in Environmental Research Letters.Alerts remain unconfirmed until two or more out of four consecutive observations are labelled as tree cover loss. Alerts that remain unconfirmed for four consecutive observations or more than 180 days are removed from the data set. You can choose to view only confirmed alerts in the menu, though keep in mind that using only confirmed alerts misses the newest detections of tree cover loss.
This report and associated material is the third in a series of interactive forest atlases of Cameroon. Readers and users of version 3.0 are encouraged to consult versions 1.0 (2005) and 2.0 (2007) for additional and more detailed information regarding Cameroon’s forest estate. Particular issues covered more extensively in these previous versions include discussions of forest legislation, forest land use classification categories, and the recent history of the forest estate. Versions 1.0 and 2.0 also offer more extensive cartographic representation. Online versions of these reports, interactive maps, and atlas data are available at http://www.wri.org/forests. For more information on areas in which the Atlas has had an impact since version 1.0 was released, please refer to Appendix 7 at the end of this document.
