Greenpeace released a couple of maps depicted the remaining intact forest and a suggested network of marine reserves (also available in pdf format). Data for intact forest cover is available in ESRI shapefile or Google Earth kmz formats. Intact forest is defined by Greenpeace as blocks that are larger than 500 square kilometres that have not been fragmented by human infrastructure development. Also available is a poster of world intact forest landscapes with explanatory text and images (jpg and pdf - sample at right).
