The dataset delineates annual forest loss in the CAZ digitized from annual 15 metre resolution LANDSAT imagery. This dataset creates a baseline for possible long-term, near real-time monitoring of encroachment and illegal logging within the Ankeniheny-Zahamena Corridor (CAZ), Madagascar. This analysis includes a summary of suspected encroachment and illegal logging from June 2006 to December 2010 within the "protected area," which consists of zones such as priority for conservation, sustainable use, and controlled settlements.

Provenance & quality
Landsat 7 SLC-off imagery at a resolution of 15 m was compared to Landsat 2005 imagery and the Change in Natural Forest Cover from 1990 to 2005 developed by the United States Agency for International Development (USAID), Conservation International and the Madagascar Ministry of Environment, Water, Forests and Tourism. The imagery was acquired from the U.S. Geological Survey (USGS) Global Visualization Viewer (Glovis), available at http://glovis.usgs.gov/.
ENVI 4.7 was used for processing and gap filling of the imagery. Visual interpretation based on shape, color, proximity to features and texture was used to digitize suspected forest encroachment using ArcGIS 9.3.1.
The data have not been validated; therefore some of the clearings are likely due to natural disturbances such as landslides, flooding, natural fires or tree falls.
