November 26, 2009--A new high-resolution map based on data from NASA's Landsat 5 and Landsat 7 satellites shows how forest cover changed (light blue) in Paraguay between 1990 and 2000. The part of the map seen above highlights the rectangular fields and narrow roads that are altering forests around the Mbaracayú Nature Reserve.

The map is part of a forest-change analysis that shows that Paraguay lost 13 percent of its forests to agriculture and other human activity between 1990 and 2000. Most of the loss has been in the Atlantic forests--tropical woodlands distinct from Amazon rain forest--east of the Río Paraguay, including those around Mbaracayú.
