Résumé:
The study seeks to demonstrate through field research and laboratory, which plants native
of the Caatinga, as xique-xique and macambira may be used in the recovery of degraded
areas. The study area is located in a project called fixing the Serra do Monte, between the
municipality the Cabaceiras and Boqueirao, both located in the micro Cariri Eastern state
of Paraiba. In semi-arid region, various forms of natural resource use may lead to
different anthropogenic processes that result in degradation. The vegetable and mineral
extraction and overgrazing of pastures and native or cultivated agricultural use on crops
which expose soil to erosion, linked to agricultural practices preservationists, are the main
causes of the degradation processes that affect the region. The rationale for the study is
given from the measurement and quantification of these two plants, gifts from natural and
spontaneous way in the study area, cataloging, counting, and frequency of individuals of
different species and families vegetating in its surroundings, the measurement of weights
of dry matter present inside the "reboleiras" that they form the natural landscape.
Although the study aimed to compare the results of analysis of soil sampled in the
degraded areas, in comparison with samples taken inside the "reboleiras" of xique-xique
at two depths. Evaluated the performance of the performance and efficiency of the
rooting of vegetative propagation plants xique-xique e macambira and planted in 7 plots
with 4 replications, between december 2008 and July 2009, we used a simple statistical
analysis where it was found rates of fixation above 75% for all months of planting the
two species planted. The study showed that both macambira as the xique-xique may well
be used as tools in a program of rehabilitation of degraded areas, due to improvements in
the soil physical structure and more percentage of organic matter present in their environment, and on further amount of species there can be perpetuated and the high rate
of success in the months from December to July, also serves as the historical and cultural
that could be used as an alternative to animal foraging.
