Large-Scale High-Resolution Forest Carbon Mapping Approach is Cost-Effective
Large-scale biomass mapping is essential to support the United Nations Framework Convention on Climate Change (UNFCCC) program to Reduce Emissions from Deforestation and forest Degradation (REDD). In close collaboration with Scientists from the Carnegie Institute of Science (CIS), PSW researchers have developed and tested an integrated satellite, airborne, and field-based mapping approach that supports high resolution biomass monitoring of tropical forest regions. CIS and PSW researchers tested this approach on the island of Hawaii at a resolution of 0.1 hectare, making it the largest high-resolution biomass mapping study of its kind. Results indicate that Hawaii Island supports an estimated 60 Tg in aboveground biomass (30 Tg C). These results and approach were presented at the Copenhagen-15 meetings in December, 2009 where they were received with great interest. These results clearly demonstrate that a combination of free satellite monitoring technology coupled with an affordable level of aircraft-based LiDAR mapping can provide spatially-resolved, regional biomass estimates that will improve the monitoring of carbon stocks, losses and recovery in forests over time. These tools are now available and can be implemented in any region of the world, making rapid forest carbon mapping a reality.
Involved in this R & D were personnel from Region 6, PSW and PNW of the Forest Service; University of California, Arizona and Alaska; and a private consultant. Forest Inventory and Analysis (FIA) Program lichen biomonitoring data were widely used in developing this product.
