Figure 2. Graphs generated by the Phenological Predictability Index (PPI) tool in BRAHMS, showing the PPI score for each of the 28 species whose data were used in the present study plotted against each species' PPI-determined maximum probability month for: A, flower buds; B, flowers; and C, fruits. PPI scores were calculated only for species with more than 50 unique records. Method 1 (phenological monitoring studies carried out in 2001 and 2012): [*], species for which only sterile plants were found in the maximum probability month. Method 2 (spot-check field excursions in July 2014 to record phenological state): species found [0], sterile; [1], with flower buds; [2], with open flowers; or [3], with fruits. Grey-shaded cells, at least one species found in its maximum probability month (July 2014 field excursions).
