A dataset of forest regrowth in globally key deforestation regions

We employed multiple remotely sensed datasets to generate the first dataset capturing forest structural regrowth, including forest height, aboveground biomass (AGB), leaf area index (LAI), and fraction of photosynthetically active radiation (FPAR), subsequent to deforestation in globally key deforestation regions at a 30 m spatial resolution. The regrowth index for each structural parameter includes regrowth ratios and rates at 5-year intervals spanning primarily from 1985 to 2020. The dataset is formatted in GeoTIFF. To accommodate the diverse temporal sequences of data across different regions, we organized the regrowth dataset by geographical regions. Within each region, we categorized the regrowth land types into secondary forests (including naturally regenerated forests and tree plantations) and other regrowth types. In secondary forest areas, we mapped the regrowth ratio and rate for each parameter (Height, AGB, LAI, and FPAR) of the secondary forest across multiple years, with intervals of 5 years. For instance, in the case of Southeast Asia, the filenames and naming conventions for the bands are: Filename: Southeast Asia_Height_regrowth.tif: Height regrowth of secondary forests following deforestation in Southeast Asia. Southeast Asia_AGB_regrowth.tif: AGB regrowth of secondary forests following deforestation in Southeast Asia. Southeast Asia_LAI_regrowth.tif: LAI regrowth of secondary forests following deforestation in Southeast Asia. Southeast Asia_FPAR_regrowth.tif: FPAR regrowth of secondary forests following deforestation in Southeast Asia. Bands of a file such as the Southeast Asia_height_regrowth.tif are: Regrowth_type_2020: Regrowth land type in 2020 following the deforestation between 1982 and 2019. The tree plantation, naturally regenerated forest and others are coded as 1, 2, and 3, respectively. Height_regrowth_ratio_year: Height regrowth ratio of secondary forests following deforestation for a target year. Height_regrowth_rate_year: Height regrowth rate of secondary forests following deforestation for a target year.
