dc.description.abstract A study of the erasslands in \/olmera \Iereda was made from A August 1979 to October 1979. One hundred and twenty stands were systematically sampled and the occurence of 118 plant species in the stands recorded. Some environmental factors were recorded and soil samples collected. Computations of the clas~ification of the vegetation using the Association Analysis Technique was made at the University of Manchester Regional Computer Center. Four distinct vegetation types were tentatively identified from the dendrogram at higher levels of the classificatory hierarchy and were statistically tested for significant contrasts. Gradients of soil pH, conductivity, hue, and cation content are positively correlated with a decreasing drainago gradient and these are negatively corrclatod with an increasing grazing gradient. en_US
