Resumen:
The objective of this study was to analyze the structural changes in Croton blanchetianus Baill.
as subsidies to define the ecological aspects that characterize its population Caatinga area in the
Western Cariri of Paraiba. The work was executed in the Reserved Experimental Space for
Studies of Ecology and Dynamics of the Caatinga – Area I 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
area were implemented for the monitoring of structural variations of the species, 96 contiguous
plots of 10 X 10. In the phytosociological survey of the adult component held in January 2013
were registered 1,078 individuals from Croton blanchetianus Baill., defining as the first in
number individuals, absolute density and relative density among the 12 species raised and the
category of the dead. Present in all 96 plots worked and when he related the Basal Area,
Dominance Absolute and Relative, Importance Value and Coverage Value was the second in
the sampled community. In January 2015 the monitoring, it was observed that the C.
blanchetianus mortality levels were high, thus the species in January 2013 passed 1078
individuals to 299 individuals in January 2015. In percentage terms, it has been that 72.26% of
the population died. For individual entering it was found that in January 2015 were surveyed
336 individuals entering the adult community, which are distributed in seven species. Of these
only four individuals of C. blanchetianus were recorded, showing a low increase rate in the
adult stratum. Therefore, the results generated are of significant importance to show
understanding of the dynamics of this species C. blanchetianus in areas of Caatinga, thus
strengthening conservation strategies, management and ecological restoration of degraded
systems in addition to enabling actions towards sustainable development of the region.
