On the slopes of one of the inselbergs within the Univ. of Ife Campus, Western Nigeria (7o32'N, 4o31'E) are islands of vegetation completely separated from each other by expanses of bare rock. The pattern of seasonal succession in one small vegetation island was studied by weekly estimation of species importance. Species importance was estimated by censusing all individuals and by measurements of cover. At the beginning of the growing season the island is dominated by ephemerals which are later replaced by drought enduring perennials. The number of individuals and species and species diversity and abundance patterns on the island over the growing season show a specific pattern which probably occurs every season.
