Resumen:
The work aimed analyze the ecological aspects in the Umbuzeiro (Spondias tuberosa
Arruda Cam.) in areas of Caatinga in the paraibano Semiarid. The areas selected for the
study they were: (1) stream of Umburana - remainder with a significant conservation
degree; (2) Reserved Experimental Area for Studies of Ecology and Dynamics of the
Caatinga of the Laboratory of Ecology and Botany - LAEB/CDSA/UFCG - area selected
as pilot for the enrichment strategies. The work involved study in the structure,
accompaniment of the dynamics of the regeneration, formation of the bank of seeds and
evaluation of the rates of survival of the umbuzeiro. For the stream of Umburana, in the
study phytosociological, the umbuzeiro (S. tuberosa) obtained a low density with just an
individual and basal area of 0.060 m2.ha-l. Related to the Value of Importance and Value
of Covering the umbuzeiro didn't also obtain prominence in the community. In the rising
of the bank of seeds this was represented by 105 species, however, of that total any
individual of the Umbuzeiro didn't germinate. This species was not also registered in the
inventory of the bank ofyoung. In the reserved area for the enrichment that of the 70
individuals' total, they died 61 what it represents 87% of mortality. Therefore, the data
present a significant contribution concerning the knowledge that involve the ecology of
the Umbuzeiro.
