A comparative study of ordinations of the Milliken Hill vegetation was carried out using da- ta of (a) presence and absence of all the species, (b) presence and absence of the woo- dy species and (c) presence and absence of the herbaceous species. The three sets of analyses produced interpretable results. In each case axis one was correlated with the al- titudinal gradient, total nitrogen and calcium. The stands at higher elevation are more ex- posed and contain higher percentages of savanna species. The higher percentage of to- tal nitrogen and calcium in the lower elevation stands is attributed to (a) more accumaula- tion of organic matter and (b) leaching at the higher elevation stands. The first axis of the species ordination separates the savanna species from the forest species. |
