要旨本文	Few studies have evaluated the structure and dynamics of forests in Madagascar. In Ankarafantsika National Park, which holds the largest of the remaining primary dry forests in northwestern Madagascar, we established a 15-ha forest dynamics monitoring plot. We mapped and identified all woody stems with a diameter at breast height ≥ 5 cm. The forest stand was characterized by small-sized stems, encompassing 35,758 tree and 513 liana individuals belonging to 140 tree and 20 liana species in 53 families. The plot was on a white-sand hill at elevations from 150 to 200 m, with a gentle slope down from southwest to northeast. Over this elevation gradient, stem density and species diversity increased with elevation, while tree height and diameter decreased. The most abundant two species, both being evergreen, exhibited opposite trends with elevation, with their abundance decreasing and increasing with elevation, respectively.
