(2005): 1, relatively untransformed (native canopy still pristine and not invaded); 2, moderately degraded (native biota dominated by alien plants); 3, transformed (urban or cultivated areas, and alien secondary vegetation); LPD, log-transformed percentages of deforestation for the period 1950–2005 per site in Madagascar; NR/Y, number of red vs yellow flower-coloured individuals censused per site in La Réunion.
