Description: This data set was created by Transparent World, with the support of Global Forest Watch. Many studies depicting forest cover and forest change cannot distinguish between natural forests and plantations. This data set attempts to distinguish tree plantations from natural forest for seven key countries: Brazil, Cambodia, Colombia, Indonesia, Liberia, Malaysia, and Peru. Given the variability of plantations and their spectral similarity to natural forests, this study used visual interpretations of satellite imagery, primarily [Landsat](http://landsat.usgs.gov/), supplemented by high resolution imagery (Google Maps, Bing Maps, or Digital Globe), where available, to locate plantations. Analysts hand-digitized plantation boundaries based on several key visual criteria, including texture, shape, color, and size. Each polygon is labelled with the plantation type and when possible, the species. A “gr” in front of the species name indicates a group of species, such as pines or fruit, where the individual species was not identifiable. The percentage of plantation coverage indicates a rough estimate of the prevalence of plantation within apolygon (as in the case of a mosaic). Types are defined as follows: Large industrial plantation: single plantation units larger than 100 hectares Mosaic of medium-sized plantations: mosaic of plantation units < 100 hectares embedded within patches of other land use Mosaic of small-sized plantations: mosaic of plantation units < 10 hectares embedded within patches of other land use. Clearing/ very young plantation: bare ground with contextual clues suggesting it will become a plantations (shape or pattern of clearing, proximity to other plantations, distinctive road network, etc) For more information on this data set and how it was produced, see the forthcoming WRI Technical Note associated with this project.
