Extended Data Figure 3: Dynamics of tropical forest fragmentation in the Americas (FRAG model).

a, Spatial patterns of fragments for different snapshots in time, and b, fragment size distributions (green bars indicate values from the FRAG model, solid black line indicates observation from remote sensing; fragment sizes ≥ 0.1 ha). The critical phase at which the spanning fragment disappears is indicated as ‘critical’. For each phase, a map of a selected subarea of 900 ha is shown (from the FRAG model, cleared sites are white and colours indicate fragment size; see Methods for details).
