Resumo:
The aim of this study was to evaluate the variability of the vegetation component considering the
ecological succession process in a Caatinga area in the Semiarid Paraiba. The work was executed
in the Reserved Experimental Area for Studies of Ecology and Dynamics of the Caatinga of the
Laboratory of Ecology and Botany - LAEB/CDSA/UFCG (7°39'38.8 '' S and 36°53'42.4 '' W;
538 m of altitude). In this space, have been deployed to monitor the evolution of ecological
succession, 17 parcels of 1x1 m. The selected area have been recorded in 404 monitoring (period
from 01/01/2013 to 07/31/2015) 7,657 individuals in 32 species (29 herbaceous species and three
the tree and shrub component). The germination peaks for species and seedlings were variable
with respect to time and precipitation. Particularly in analysis the succession dynamics of the
shrub and tree component, germinated on the monitored system: Jatropha mollissima (Pohl)
Baill, Poincianella pyramidalis (Tul.) L. P. Queiroz and Croton blanchetianus Baill. The species
were represented by three, one and 35 individuals respectively. Considering the individuals
registered the shrub and tree component, registered is that they all died in the monitored parcels.
Therefore, the data generated are shown of great importance for the understanding of the elements
that define the succession dynamics of the vegetation component, offering subsidies for the
restoration of degraded ecosystems.
