|Level||Data available||Data not usually available|
|Community forest management projects registered for REDD+||Activity data||Area degraded at the start and at the end of the accounting period (derived from forest inventory and possibly modeling)||Historical rate of change of degraded area (not visible in medium resolution satellite images, high resolution images not available for earlier periods)|
Stock change over the accounting period (monitored by forest inventory)|
Independently verified, qualitative assessment by experts that area had been degrading in the past.
|Historical rate of biomass loss per hectare (not measurable from satellite imagery, no earlier forest inventories)|
|National level||Activity data||Would require geographic modeling over broad areas||Areas subjected to degradation by communities in the past, and rate of change of this area|
|Emissions factors||Tier 2 level data on typical standing stock levels||Rate of change of standing stock|
