Forest carbon-stock estimates based on National Forest Inventory data

Indonesia's forests were inventoried from 1989 to 1996 (phase 1) and from 1995 to 2000 (phase 2) by the Forest Planning Agency ('the Agency') at the Ministry of Forestry
as part of a collaboration between the Government of Indonesia and the United Nations Food and Agriculture Organization. The objective of this National Forest Inventory (NFI) was to assess foreststand conditions, stocks, growth rates and tree diversity across the
landscapes of Indonesia. An improved version of the NFI became known as the Forest Assessment and Monitoring System. This data set had not so far been used to estimate
aboveground tree biomass and carbon stock in Indonesia, as quality control of the data had not been completed. We provide an overview of the data and derive carbon-stock
densities for different forest types and locations that can be used for estimating historical, aboveground CO2 emissions from deforestation 2 and forest degradation.
