Factores que influênciam a regeneração e estabelecimento natural da Sclerocarya birrea-Nkane (A. Rich) Hochst 1844: estudo de caso da região de Goba-Maputo

Abstract

The study was carried out in the Goba region, with the general objective of contributing to the knowledge of the determining factors in the regeneration and natural establishment of the Sclerocarya birrea species. Specifically, it is intended to identify the methods of seed dissemination of this species; identify the factors that contribute to the dissemination of the seed of this species; to identify the factors that contribute to the regeneration and recruitment of Nkanhe and, finally, to evaluate the human factor in the distribution of the species' seed. The study took place in two distinct areas concerning exploration activity, among others. Based on a forest survey "physical study" and a "social study" survey of the local community of Goba (with a sample of about 30 people) the necessary information was collected for the analysis of this study. However, direct field observations were also made to collect additional information deemed relevant to the study. Overall the results of the social study showed that the local community of Goba does not plant Nkanhe trees. The study noted that this community is aware of traditional management rules that contribute to the regeneration and natural establishment of the species. The results of the physical study showed that slope, altitude, soil disturbances and exposure are some of the factors that contribute to the regeneration and natural establishment of Sclerocarya birrea in the study area. Finally, the main conclusions: The Nkanhe in the study area does not need specific management as it does not run the risk of disappearing or degrading. This species does not easily germinate under the hand tree and is widely distributed in farms and around houses in the Goba region.
