Resumen:
Caatinga ecosystems has proved holder of a biologically rich and accordingly understanding of
successional processes in these areas are relevant to generate information that will strengthen actions
for conservation biology and restoration of degraded areas. Thus, this study aimed to evaluate the
ingrowth and mortality of tree and shrub species in a defined initial stage of succession in the Western
Cariri of Paraiba area. 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. Data were collected
between 12/12/2012 to 03/10/2014, considering 03 weekly monitoring. In the group of 17 parcels
sampled for the study of ecological succession 25 individuals tree and shrub component were
recorded. Species with their own individual ingrowth numbers and the number of mortality are
respectively listed below: Jatropha molisima (Pohl) Baill. three individuals (mortality - three), Croton
blanchetianus Baill. with 21 individuals (mortality - 20) and Poincianella pyramidalis (Tul.) LP
Queiroz with one individual (mortality - one). Therefore, the data generated in this work are shown of
great importance for the understanding of the elements that define the vegetation dynamics in areas
characterized by the initial process of succession.
