Grazing and biodiversity Caatinga 1

Research hypothesis: grazing intensity and stage of secondary succession after deforestation affect richness, diversity, plant composition of herbaceous and tree - shrub layer and forest structural traits (density, biomass, basal area an others) of tropical dry forest. Main findings: Grazing intensity, succession stage and interaction between both showed significant effects on most of variables. Grazing intensity did not disrupt natural succession process.
