Similarity in postpartum plant use in the Nam Noi and Nam Pheo watersheds. Similarity is plotted using non-metric multidimensional scaling (Kruskal Stress 0.111). Data combines the in-depth study of Kry childbirth plant use with Brou, Saek and Kry postpartum data . Distances between points are relative similarities. Points represent individual village datasets, and for 'Kry' the overall postpartum-used plants from this study. Icons represent: Brou (Diamond), Saek (Square), and Kry (Triangle). Clustering of ethnic groups is evident.
