Ottaviani et al 2017_Ecol Evol_bark thickness data

Bark thickness data were collected in the field for 14 plant species, from seven granite outcrops across an aridity gradient in Southwestern Australia, in 2012. In each study site, 3-4 species were sampled. For each species 10 individuals were sampled (in each outcrop). For each plant sampled, 5 different bark thickness measurements were collected, then averaged
