A total of 31’466 plots were identified for potential inclusion into AVA (Walker et al. 2019b). The map shows the number of identified vegetation plots for each Arctic bioclimatic subzone (Yurtsev 1994). For each plot, the species diversity is recorded according to the Braun-Blanquet or a similar approach.
