Estudo sobre as causas de degradação do mangal e o nível de regeneração em Catembe

Abstract

This work consisted mainly of studying the causes of mangrove degradation and its level of regeneration, as well as evaluating the socio-economic aspects of the local community, related to the use of mangrove tree species in catembe, maputo province, based on the interviews and in the inventory in tracks. In the inventory carried out, the heights, the dap of 2008 trees with dap > 8 cm were measured and the seedlings that constitute the natural regeneration were counted. Four mangrove species that occur in catembe were also identified, such as: avicennia marina, bruguiera gymnorrhiza, ceriops tagal and rhizophora mucronata. Of these species, avicennia marina is more representative in all parameters studied, compared to the other three species, while ceriops tagal is the least representative. The interviews carried out revealed that the local population only exploits the mangroves for consumption, extracting products such as firewood, poles, poles and wood for the construction of boats. Although the catembe mangrove is currently controlled by the emodragái in remote times, the local population and those from other areas cut down many mangrove trees to produce charcoal for sale, which was one of the main causes of mangrove degradation in catembe. The regeneration potential that this mangrove presents shows that in the near future, many small trees will move to the upper diameter classes. In catembe, the local population is aware of the existence of some local rules for the management of mangroves and trees, such as: do not burn, do not cut fruit trees, mangroves and timber trees. It is through these rules that the few forest resources existing in this area are conserved
