Above-ground biomass recovery in managed tropical forest in the Jari Valley, Eastern Amazon. Repositório Alice
SANTOS, A. C. dos; SOTTA, E. D.; GUEDES, M. C.; BLANC, L..
Tropical forests play an important role in maintaining the regional rainfall regime and global climate, besides representing a significant stock of carbon. This study aimed at evaluate above-ground biomass (AGB) recovery, after reduced-impact logging (RIL) in a managed forest on the Jari River valley. The data were collected in 15 plots (100 m × 100 m) in the management area of the Jari Florestal Company. To estimate AGB we used a local equation adjusted for forests in the eastern Amazon.

Collaborative Monitoring of Production and Costs of Timber Harvest Operations in the Brazilian Amazon Ecology and Society
Pokorny, Benno; University of Freiburg; benno.pokorny@waldbau.uni-freiburg.de.
Timber companies and policy makers in the Brazilian Amazon urgently need financial information on forest management. Results from a few experiments, case studies, and surveys have been groundbreaking, but are insufficient. A strategic partnership between timber companies and research organizations is needed to generate additional information. This paper presents a tool for monitoring production and costs of forest operations to facilitate such collaboration. The tool provides useful information for companies and, at the same time, generates reliable data for research. Selected results are presented on production, capacity, and costs to demonstrate the usefulness of the information that can be generated. These results are based on the first 2 years of...

Optimal selective logging regime and log landing location models: a case study in the Amazon forest. Repositório Alice
SILVA, P. H. da; GOMIDE, L. R.; FIGUEIREDO, E. O.; CARVALHO, L. M. T. de; FERRAZ FILHO, A. C..
Reduced-impact logging is a well known practice applied in most sustainable forest management plans in the Amazon. Nevertheless, there are still ways to improve the operational planning process. Therefore, the aim of this study was to create an integer linear programming (ILP) to fill in the knowledge gaps in the decision support system of reduced impact logging explorations. The minimization of harvest tree distance to wood log landing was assessed. Forest structure aspects, income and wood production were set in the model, as well as the adjacency constraints. Data are from a dense ombrophylous forest in the western Brazilian Amazon. We applied the phytosociological analysis and BDq method to define the selective logging criteria. Then, ILP models were...
