Brazil Eyes Microchips In Trees For Forest Management
A chainsaw buzzes, branches snap, and an Amazon tree crashes to the ground. It could be just another of the thousands of trees felled each year in Brazil's portion of the world's largest forest except for one detail: a microchip attached to its base holding data about its location, size and who cut it down. With a hand-held device, forestry engineer Paulo Borges pulls up the tree's vital sta

Congo Among Nations Advancing On Forest Carbon
Nations including Democratic Republic of Congo are making surprise progress toward taking part in a $200 million project for slowing deforestation from late 2010, World Bank experts said. They also said Latin America, with forested nations around the Amazon, had strong incentives to take part since most of the continent's greenhouse gas emissions came from deforestation and shifts in land use,

Brazil says rate of deforestation in Amazon continues to plunge
Large-scale deforestation in the Amazon has declined by 47.5% over the past 12 months, according to a preliminary survey by the Brazilian Ministry of Environment using a low-resolution satellite. The figure is one of the largest declines since measurements began 20 years ago.
