The plant populations of both plots were determined by means of twenty-five quadrats of 0.1 square meter each in the spring of 1950 and in the early autumn of 1950, 1951, 1952 and 1954. In each quadrat the living area1 (foliage) cover was estimated to the nearest whole percent of the total quadrat area. From these data the relative frequency, and the relative cover were calculated. The relative values were obtained by dividing the frequency or cover of a given species by the sum of the
