Grass cover dataset used in Forest recovery pathways after fire, drought, and windstorms in southeastern Amazon (Maracahipes et al. 2026 PNAS). README: Grass Coverage Area 1 The data in this folder consists of a temporal raster stack of grass coverage in Area 1 of Tanguro Field Station in Mato Grosso, Brazil. Grass was documented in 2012, 2015, 2022, and 2025. Rasters were created from gridded observations of grass coverage in the plot and values were assigned according to species. It also contains a .csv with the % coverage of each species, for each year, for the Burn plots only (B1yr, B3yr). The shapefile for the plots is uploaded as well. Original data was collected by Divino Silverio and the team at the Tanguro Field Station. Description of the data and file structure There are four rasters/bands in the raster stack Grass_20122025.tif. Each band is one year (2012, 2015, 2022, 2025). The values in the raster are as follows: 0 = Forest1 = Andropogon gayanus2 = Aristida longifolia3 = Grass-mix4 = Pennisetum sp.5 = Other non-grass6 = Shaded Aristida longifolia* Shaded Aristida longifolia is A.longifolia growing under forest canopy. It is a new classification added in 2025. Previous surveys did not quantify grass under tree cover. For the shapefile, the treatment plots are B1Yr, B3Yr, and Control. B1Yr was burned once every year from 2004-2010, B3Yr was burned every three years during that period, and the control was never burned. For the csv, the columns are as follows:A - ignoreB - Year: year data was collectedC - Grass speciesD - PixelCount: how many pixels were given the specific value for each species for each yearE - Percent: the percent of all of the pixels in the plot for that year that each species accounted for. This data was used to create a sankey diagram. Sharing/Access information This is a section for linking to other ways to access the data, and for linking to sources the data is derived from, if any.
