Supplementary material Figure S1. Study area and global distribution of Z. abelicea throughout the four main mountain regions of Crete: from west to east: Levka Ori (2453 m a.s.l.), Ida Mountains (2456 m a.s.l.), Dhikti Mountains (2148 m a.s.l.) and Thripiti Mountains (1476 m a.s.l.) (Jahn and Schönfelder, 1995). Dots represent sampling sites and colored zones show the species’ distribution in the Levka Ori Mountains and Dhikti Mountains. For the Ida Mountains, sampling was done within the two only existing populations (KED and PSI). This was also the case in the Thripiti Mountains where the only known population (STA) was sampled.

Fig. S3. Shrubby, dwarfed and totally browsedZ. abelicea tree of the small category (KED_S1).
Fig. S4. Z. abelicea individual of the intermediate category. The tree is browsed at its base but the highest branches have started to escape browsing (LAS2_M1).
Table S1 Main geographical parameters of sampling sites, number of sampled trees in each habit category and observation of fruiting trees in 2010. S, M and L stand for the three tree categories, namely small, dwarfed and browsed trees, intermediate trees and large, non-browsed and normally growing trees. Only large trees have been observed and known to produce fruit.
