Two-dimensional nonmetric multidimensional scaling (NMDS) ordination of seed banks and above-ground vegetation after 14 years of precipitation changes at Buxton, UK. Open symbols represent above-ground vegetation data and closed symbols seed bank data. Treatments are represented by colours: black = control, blue = watered and red = drought. Ordination is based on the relative abundance of species data. There were 5 plots in each treatment. The location of ordination points indicates the degree of similarity between each one. The ordination confirmed a difference between seed bank and above-ground vegetation communities
