The tropical premontane moist forest is one of the most destructed Iife zones in Costa Rica. For such regions, a small natural preserve system has been proposed. An inventory of trees greater than 3.5 cm in diameter at breast height was done in one hectare urban forest patch that was left under natural regeneration for 30 years. The inventory included 940 individuals of at least 55 species and 32 families. A Holdridge Complexity Index of 58 was obtained. There was a strong dominance by small-diameter trees of successional and exotic species.
