             <p>Upcoming upgrades to FORMA include improving the resolution to 250 × 250 meters, and expanding coverage to tropical dry forest and eventually to other biomes across the global scale.</p>

                <p>For the purpose of this study, “tree cover” was defined as all vegetation taller than 5 meters in height. “Tree cover” is the biophysical presence of trees and may take the form of natural forests or plantations existing over a range of canopy densities.  “Loss” indicates the removal or mortality of tree canopy cover and can be due to a variety of factors, including mechanical harvesting, fire, disease, or storm damage.  As such, “loss” does not equate to deforestation.</p>
  
                <p>When zoomed out, it appears that all tree cover loss occurs in 2001, but in reality loss happened gradually over the study period. As you zoom out, adjacent pixels representing loss—which may have occurred in different years—must be combined into a single pixel to remain visible on a larger scale. Authors of the study decided to display these “aggregate pixels” according to the year loss first occurred in any of the constituent pixels (often 2001 for low zoom levels with very large aggregate pixels). Zoom in for greater detail of when and where loss has occurred for individual 30 × 30 meter pixels.</p>
