The secondary forests in Flower Town were investigated from the viewpoint of fragmented forest (forest island), in order to clarify the actual conditions of the forests. It was recognized that number of species in a fragmented forest and its area was significantly correlated with a correlation coefficient of 0.95. The fragmented forests were characterized by the invasion of the trees for landscaping and by the absence of the rare species occuring in the near non-fragmented forests. In the small-sized fragmented forests, it seemed that the herbaceous plants were relatively inhibited by arid soil condition. We examined that the necessary areas and numbers of the fragmented forests for conservation.
