Forest Recovery in the Amazon

Intense deforestation in recent decades has made forests in unprotected areas of the southwestern Amazonian state of Acre highly fragmented. Severe drought events in 2005 and 2010 have also led to extensive forest fires across the region. A new dataset seeks to examine the impacts of forest fire and fragmentation on forest biomass and structure in Acre.

Forest Inventories at Burned and Unburned Tropical Forest Sites, Acre, Brazil, 2014

This dataset provides measurements of diameter at breast height (DBH) and species identification of trees for inventories taken at five tropical forest sites in Acre state, Brazil, in the southwestern Amazon region. The sites include one in a forest reserve (Reserva Bonal) and four within forest fragments situated on private property. The inventory sites include forests burned in 2005 and 2010 and also unburned forests. Surveys were conducted in July and August 2014.

The data were used to characterize the post-fire forest recovery of sites from wildfires in 2005 and 2010 and determine the edge effects on forest aboveground biomass (AGB) and stem density in different tree size classes in the five fragmented forest areas.
