Notes: Zone areas that fall outside of the study area have also been included in the calculation, which explains that the CPZ equals to 100% when the MFD is equal to or greater than 1200 m (i.e., the CPZ is slightly over-estimated).

 

TABLE D2. The graph components’ areas as fractions of the total forest area. The largest component, the second largest component, number of components, and components with an area equal to or below 10 ha are included in the table.
