Due to the paucity of long-term biodiversity trend data in tropical.Protected areas we used, the published data describing the biodiversity 'health' of 60 pan-tropical reserves within 36 countries (Laurance. Et al, 2012). The health index is an integrated assessmentof biodiversity trends across 10 guilds deemed sensitive to environmental.Changes by local experts (Laurance et al, 2012). Six of these.Guilds are considered 'disturbance avoiders' (apex predators large,,Non-predatory vertebrates primates understory insectivorous,,,Birds large frugivorous, birds and large-seed old-growth trees),And the remaining four are generally 'disturbance-favouring guilds.'(pioneer and generalist trees lianas vines exotic, and, animals and.Exotic plants) (Laurance et al, 2012). The health index for each.Reserve is an average of the mean trend values (1 = declining.Abundance of disturbance-avoiding guilds or increasing.Disturbance-favouring, guilds 0 = no change and 1 = increasing disturbance-avoiding / decreasing disturbance-favouring across.) The guilds (Laurance et al, 2012).
