For 2003 we are going to identify and measure biomass, canopy damage, fuel loads and regrowth and in different types of burned and logged forest in northern Mato Grosso (Guaranta), similar to what was done for Santarem/ Belterra site and started for Paragominas site in 2001 and 2002. The goal is to identify differences in forest structure and its response to disturbances by to fire and logging among different types of forest (dense forest intensive logged, dense forest moderate logging, and transitional forest intensive logging). More specifically, the field work will be done in private property areas and account for direct measurements of forest structure, informal field interviews to check and reconstruct the forest disturbance history and ground truth for remote sensing analysis. Logging and fire maps are already done for this area using remote sensing image classification and visual interpretation. The field measurements will be used to parameterize the remote sensing image and improve the classification done previously.
For 2004 and 2005, we will expand the study to open forests with intensive and moderate logging and to transitional forests with moderate logging. The existing grant ends in 2003, however, and the fieldwork for 2004 and 2005 will depend on obtaining renewed funding.
