Workshop Silas Little Experimental Forest, NJSeptember, 13-17, 2010 • André Monteiro • Forest EngineeringandAdjunctResearcher • Imazon (AmazonInstituteofPeopleandtheEnvironment) • Coodinator of theProjects • Monitoring and TransparencyfortheForest Sector in the Amazon • Inventories of ForestDegradation in theBrazilian Amazon
Forest Transect Method • Forest inventory (n=62) • Transects (10 m x 500 m) • Covered a range of forest degradation intensity and undisturbed forests. • All trees with DBH >10 cm were mapped along 10 m by 500 m transects (i.e. 0.5 ha). • Sub-parcels (10 m x 10 m; 0.1 ha) were created every 50 meters along each transect and all trees <10 cm DBH were mapped. • Information surveyed • Tree species • DBH • Canopy gap • Lianas • Soil disturbance • Live and dead • Woody litter • Aboveground biomass • Estimated using allometric equations (Gerwing 2000)

C Stocks Change vs NDFI AGLB vs. NDFI Loss of C Stocks with Intensity of Forest Degradation Degradation Intensity
Areasofresearchinterest • Methods to measure carbon stocks of forests using rapid forest inventories. • Measurement of forest biomass using laser instruments and Lidar technology. • Integration of field data of forest carbon stocks with remotely sensed data to support of strategies for project of REDD. • Modeling of forest carbon dynamics and ecosystem services.
