2. Inter-governmental Panel on Climate Change

3. Kyoto Protocol Reduce greenhouse gas emissions (CO2 and methane) to 5% below 1990 levels by 2008 Forestry: Can offset emissions by sequestering carbon Only applies to reforestation or afforestation in developing countries In developed countries, 5 % of emissions can be offset

8. Quantifying Carbon Storage: Multiple components and fluxes

9. Dendrometer bands on all tally trees are used to measure wood increment over periods shorter than standard FIA remeasurement interval. Measurements are made annually (major growth occurs in the spring).

10. Eight litterbaskets are placed on each plot (2 baskets per subplot) where they do not interfere with other indicator measurements. Litterfall data are collected at one-two month intervals year-round. Annual results are calculated per plot as the mean of these litter measurements.

14. Carbon plantation in the Phillipines 311 million acres (126 million hectares) of low-yield cropland and pasture Converted to forests, would sequester 50 tons of carbon per ha per year

19. Estimates of potential carbon credit values range from $2 to $60 per ton of C. Kyoto agreement not yet ratified, so future value not yet established. Could increase substantially as international carbon markets develop Foresters can view carbon revenue as supplemental in managed forests. Carbon value co-varies with saw timber quality, so this may be an advantageous management approach where high yield fiber production is not the dominant objective Carbon Revenue
