Abstract

We mapped and measured all of the Adansonia rubrostipa trees in 40 ha of dry deciduous forest in Kirindy Forest, Menabe, western Madagascar. Survey effort was split between three compartments which had been heavily logged or selectively logged for timber trees, not including A. rubrostipa, in the 1980s, or which remained unlogged. We recorded 304 trees ranging in stem diameter at breast height from 5 to 221 cm. Trees were most abundant and the majority of regeneration was recorded in the unlogged compartment. Regeneration was generally poor in the two logged compartments. We suggest that seed predation and poor seed dispersal contribute to a generally ageing population, and that the dense shrub cover resulting from disturbance during logging impedes seedling establishment.
