Global 30m forest cover loss map (Hansen et al 2013) for 2001-2019 (updated to include 2020) is disaggregated into forest loss due to fire vs. other disturbance drivers. The map matches the sample-based area estimates of forest loss due to fire ± SE for all continents except Africa. This allows producing sub-regional map-based area estimates with a measure of uncertainty. The sum of map pixels with code 4 (high certainty of forest loss due to fire) corresponds to sample area estimate minus SE, adding code 3 (medium certainty) to code 4 (high certainty) pixels results in map area matching the sample-based area estimate, and adding code 2 (low certainty) pixels to codes 3 and 4 (medium and high certainty) yields map area matching sample area estimate plus SE. Code 5 corresponds to all forest loss due to fire in Africa; code 1 corresponds to forest loss due to other (non-fire) drivers.
