Abstract: | We tested the relationship between the length of pasture use and the density, richness, and composition of naturally regenerating tropical seasonal deciduous forest in pastures. We sampled regenerating trees in 25 pastures distributed in four age classes ranging from < 6 to 40 yr of use. Density and composition of regenerating trees did not change with pasture age, but richness was lower in 25- and 40-yr-old pastures. Nonetheless, a number of species seem to be able to resprout even after 40 yr of ranching. |
