Spatially explicit analysis of field inventories for national forest carbon monitoring

David C. Marvin, Gregory P. Asner

Policies that incentivize forest conservation by monetizing forest carbon ultimately depend on the accuracy of carbon stock estimates. Often, these estimates are based on field inventory sampling. In…
