Amazon natural regenerating forest age

We access the land use and land cover time series product available for the Amazon for the year 1985-2019 (MapBiomass collection 6). The MapBiomas is based on the classification of Landsat images, map of annual land use and land cover at 30 m spatial resolution. We initially classified each pixel in each plot within site following MapBiomaClass and we reclassified in Forest, Secondary-forest, deforestation and others for each year in a temporal series 1985-2019.We classified the land cover maps into two categories: forest (including forest and secondary forests) and non-forest (including agriculture and pasture classes)
