Health categories of palm trees obtained from the visual health assessment scale (12/12), adapted from the studies of Blair et al. (2010ab) [26,27] and Bond (2012) [28]. In the vertical dimension, the raw values of the LCR (A) and CQ (B), and in the horizontal dimension, the standardized data (mean = 0, SD = 1.0). Key colors: red-critical condition (C), orange-medium condition (M), light green-normal condition (N), and dark green-excellent condition (E). A simple “sketch” of the appearance and condition of the “crown” is included in each case.
