Summary

As part of the U.S. Congress' mandated land carbon inventory, administered by the U.S. Geological Survey, Forest Service scientists have completed a wall-to-wall carbon assessment for the state of Hawai'i, specifically: (1) carbon storage in soils (to a depth of 1 meter or 1.09 yard); detritus (litter and coarse woody debris); and above- and below-ground live biomass; (2) ecosystem productivity, including gross and net primary production; and responses of items (1) and (2) to climate change, species invasions and land-use change. Methods include the linking of remote sensing (MODIS, airborne LiDAR and Landsat) data, U.S. Department of Agriculture Forest Service Forest Inventory and Analysis program data for Hawai'i, literature-based data upon in-situ sampling, and state and transition modeling to understand current and future conditions and characteristics. The scientists analyzed data by island, vegetation type and carbon sequestration. The assessment provides a better understanding of the significant threat posed by an expanding non-native fire regime on future carbon storage, as well as an improved understanding of landscape-scale patterns for, and drivers of, carbon storage and productivity.
