Agroforestry and silvopastoral systems

The aim of this study was to investigate how the temporal patterns of the most abundant species in the communities determine the succession processes in different vegetation formations of the Cerrado Biome.In the first inventory, in 2010 in the Cerrado stricto sensu and Cerradão, the diameter of all individuals 30 cm above the ground (DAS, 0.30m) ≥ 5.0cm was identified and measured.For the SSF in 2011, all living individuals with breast height diameter (DBH) ≥ 5,0 cm were measured and identified.The second inventory in the three phyto-physiognomies was carried out in 2015, when the same criteria of the previous inventory were adopted.Mortality was higher than recruitment, in all populations studied, 15 populations had no individuals recruited and only two species (Bowdichia virgilioides Kunth and Caryocar brasiliense Cambess) did not lose individuals.Changes in dynamic parameters varied among populations and recruitment was higher in populations with the highest loss of individuals, indicating that these species, regardless of their phyto-physiognomy, have a greater regeneration potential after disturbances.
