title: Spatial distribution of planted forests in East Asia (final products)

description: The shapefile depicts the distribution of planted forests in East Asia (China, Japan, ROK, and DPRK) and associated dominant tree species to the genus level. The dataset is in a shapefile where each polygon is 0.009° by 0.009° (approximately 1km<sup>2</sup>) in size within the forested area of 2020 (5m or greater in tree height) based on the FAO’s definition of “forest.” <br> For each polygon, attributes include information on planted forest, dominant tree species, and geospatial entity as follow: <strong>ID:</strong> Polygon ID <strong>Biome:</strong> Biome classes used in the study <strong>Country:</strong> Country <strong>Prc_Pln:</strong> Percent planted forest predicted by the three models (upper bound, midpoint, and lower bound). The values are means of the three models, which is the main result of our study. NA for ROK and majority of areas in Japan, where national planted forest maps were used as a final planted/natural label (see References). <strong>Prc_P_U:</strong> Percent planted forest predicted by the upper bound model. NA for ROK and majority of areas in Japan, where national planted forest maps were used as a final planted/natural label. <strong>Prc_P_L:</strong> Percent planted forest predicted by the lower bound model. NA for ROK and majority of areas in Japan, where national planted forest maps were used as a final planted/natural label. <strong>Type:</strong> “Planted” or “Natural” forests based on the main result. For our predicted percent planted forest, “Planted” if Perc_Pln is 0.5 or greater and “Natural” if Perc_Pln &lt; 0.5. For Perc_Pln = NA, national planted forest maps were used to determine if the given polygon is a planted forest, and if not, “Natural.” <strong>Typ_Upp:</strong> “Planted” or “Natural” forests based on the upper bound model. For our predicted percent planted forest, “Planted” if Perc_Pln_Upper is 0.5 or greater and “Natural” if Perc_Pln_Upper &lt; 0.5. For Perc_Pln_Upper = NA, national planted forest maps were used to determine if the given polygon is a planted forest, and if not, “Natural.” <strong>Typ_Lwr:</strong> “Planted” or “Natural” forests based on the lower bound model. For our predicted percent planted forest, “Planted” if Perc_Pln_Lower is 0.5 or greater and “Natural” if Perc_Pln_Lower &lt; 0.5. For Perc_Pln_Lower = NA, national planted forest maps were used to determine if the given polygon is a planted forest, and if not, “Natural.” <strong>Genus:</strong> For Type = “Planted”, this attribute indicates the predicted dominant genus. NA for Type = “Natural”. <strong>Gns_Upp:</strong> For Type_Upper = “Planted”, this attribute indicates the predicted dominant genus. NA for Type_Upper = “Natural”. <strong>Gns_Lwr:</strong> For Type_Lower = “Planted”, this attribute indicates the predicted dominant genus. NA for Type_Lower = “Natural”. <strong>Area_m2:</strong> Polygon area in square meters. <br> Planted forest in this map includes forests planted for restoration purposes, commercial plantation, and other artificial planting for other purposes, such as for landscape and disaster prevention, of all ages. <br> Raster files are available for percent planted forest, type, and dominant genus, where 1 = "Planted" and 2 = "Natural" for the type. Numbers for dominant genera are as follows: 1 = Abies 2 = Acacia 3 = Betula 4 = Camellia 5 = Castanea 6 = Cedrus 7 = Cryptomeria 8 = Cunninghamia 9 = Eucalyptus 10 = Larix 11 = Liriodendron 12 = Morus 13 = Picea 14 = Pinus 15 = Populus 16 = Quercus 17 = Robinia <br> References -Biodiversity Center of Japan. <em>Vegetation Survey (7)</em> https://www.biodic.go.jp/moni1000/findings/data/index_file.html (2021). -Kim, K.-M., Kim, C.-M. & Jun, E.
