Answer:
Explanation:Estimated forest cover: Annual figures after 1985 come from MapBiomas. Prior to 1985, the data comes from several sources.
Deforestation (INPE) Brazil's National Space Research Institute (INPE) calculates deforestation on an Aug 1-Jul 31 "year" so the annual figures presented in this table do not represent deforestation that occurred on a Jan-Dec basis. This also partly explains the discrepancy between this column and the "Natural forest cover change" column.
Natural forest cover change: This number reflects the annual difference in MapBiomas data, which is reported on an annual basis, rather than the Aug 1-Jul 31 basis used by INPE. Additionally, unlike INPE data, MapBiomas accounts for forest loss due to fire. A negative number in this column suggests forest recovery or regrowth over the prior year.
Forest cover as % of pre-1970 cover: Percentage estimate of how much natural forest remains in the Brazilian Amazon relative to the pre-1970 estimate.
