| Résumé: | The structure and regeneration patterns of Mida Creek
mangrove vegetation were studied along belt transects at
2 forest sites of Mida Creek (3°20'S, 40°00'E): Uyombo and
Kirepwe. Based on the species importance values, the
dominant mangrove tree species in Mida were Ceriops
tagal (Perr.) C. B. Robinson and Rhizophora mucronata
Lamk. Tree density varied from 1197 trees ha–1 at Kirepwe
to 1585 trees ha–1 at Uyombo and mean tree height was
higher at the former site compared to the latter. The sizeclass
structure at both localities of Mida showed the
presence of more small trees than large ones. Spatial
distribution pattern of adults and juveniles varied greatly
between sites and they showed a close to uniform pattern
(Morisita’s Index I0 << 1) for trees, but a tendency to
random distribution (I0 = 1) for juveniles. The present paper
shows that unmanaged but exploited mangroves do not
necessarily disappear, but change qualitatively from locally
preferred R. mucronata to the less preferred C. tagal.
Whereas the effects of this change on the ecological
function of the mangrove cannot be estimated yet, the
economical function of the mangrove has evidently weakened. |
