Remotely-sensed images with high spatial resolution (Landsat) spanning 1986-2005, complemented by training sample data collected in 2006 and 2007, were used to define forest versus non-forested areas in three communities in Madre de Dios, four communities in Acre and four communities in Pando. The land cover classifications were used to detect areas of change in four paired image dates. Socio-economic data was collected in the communities through annual and quarterly surveys with 63 households in Pando, 59 in Acre, and 28 in Madre de Dios from June 2006 through August 2007. We found minimal deforestation and extremely high forest income dependency in sampled communities. In 2000– 2005, deforestation occurred in already fragmented areas and along roads, with most deforestation in Acre and least in Pando.
