The direction of the forest protects an important role in the protection of coastal dunes, which does not prevent the advance of sea waters in destruction of biodiversity along it. Furthermore, a preservation of this coastal ecosystem brings economic, environmental, social benefits and for the resident communities around it, as well as the tourist communities. In this context, there was a need to characterize the floristic, phytosociological and ethnobotanical aspects of the coastal coast of the Maputo Special Reserve, associating this knowledge and future conservation gains in local, regional and global terms. Therefore, this study according to the following methodological procedures: 1) The collection of samples of all the specimens was made, WHERE a collection of samples and samples of all their respective ones was made; 2) analysis of floristic similarity between the coastal forest of the Maputo Special Reserve and the namesakes of Mozambique, from other countries on the east and west coast of Africa; 3) the horizontal structuring of the sociological data, which consists of the data structure and the vegetation vertical; 4) characterization of the canopy opening; 5) pedological, WHERE the soil was collected; and 6) ethnobotanical survey, which had the help of semi-structured interviews and meetings with the local population. Data were analyzed by the PAST and RStudio program. Based on the data, we had the following results: a) the largest number of individuals are trees, of late secondary stage, without species at risk of extinction and of zoochoric seed dispersal and melitofolia pollination. The vegetation of the studied area is more similar to those of the east African coast and very little similar to those of the west coast of Africa. The different climatic environments that gave rise to different terrestrial ecoregions may have contributed to the high and low floristic similarity between the coastal flora of East Africa and West Africa. b) There are differences in structure and composition in the distribution of species in the forest remnant that was influenced by environmental variables such as calcium, potassium, sodium, humidity, canopy opening and organic matter. These results reinforced the need to create conservation strategies to minimize the degradation of coastal dunes in regions outside protected areas and the consequent loss of biodiversity in these forest ecosystems in these environments. c) All plant species were trees (100%). Mimusops caffra had the highest use value (2.56). The most cited categories were medicinal and construction (40 and 28%). The most cited medicinal plants were Acacia kraussiana and Bridelia cathartica. Most of the plant parts used are roots and stems (75%). The present study made a valuable contribution to the knowledge of the floristic composition, the structure of coastal vegetation, local knowledge and the benefits of the forest resources of the Maputo Special Reserve.
- ItemLógica fuzzy na determinação de fragmentos florestais para coleta de sementes(Universidade Federal do Espírito Santo, 2017-02-17) Peluzio, Telma Machado de Oliveira; Fiedler, Nilton César; Kunz, Sustanis Horn; Santos, Alexandre Rosa dos; Ferrari, Jéferson Luíz; Abreu, Karla Maria Pedra deThe Brazilian rain forest is fragmented due to the great exploitation in the process of colonization of the country. For the maintenance and protection of the different ecosystems, a series of legal instruments were adopted, which, when associated to the technological and mathematical tools, especially the Fuzzy logic, allow the adoption of criteria closer to human thought. In the present work, the objective was to select potential forest fragments with a higher degree of conservation for the collection of seeds that meet legal requirements, through the use and association of landscape ecology with Fuzzy logic. The study was carried out in the Itapemirim river basin in the state of Espírito Santo, through the following steps: obtaining the Landsat 8 satellite image; photointerpretation and classification of forest fragments by size class in which: A less than 5 ha, B between 5.1 and 50 ha, C between 50.1 and 300 ha, and D greater than 300 ha; evaluation of the dynamics of the metrics indexes of the area landscape, density and size, shape, border, central area and proximity; application of the Fuzzy logic and their respective Small and Large membership functions, and the Gamma overlay function; selection of potential forest fragments with higher degree of conservation of the seeds for collection; Shannon Wiener diversity, Pielou equability, Bray-Curtis dissimilarity, quality and stem health according to the Brazilian Forestry Society standard, and the Payandeh index to evaluate the pattern of spatial distribution among forest fragments classified as high and low potential for seed collection. 7,515 forest fragments were determined, occupying 19.21% of the study area. Size class A has a smaller territorial area, greater number of fragments and extinction risk due to increased edge. Class D has lower number of fragments, larger area and better condition for seed collection, even with increased edge. Two fragments classified as high (Fragment 1) and low (Fragment 2) were selected, respectively, for the collection of forest seeds. In fragment 1; 1,670 individuals were sampled, corresponding to 172 species, 103 genera and 40 botanical families. In fragment 2; 1,526 individuals, 135 species, 92 genera and 40 botanical families were sampled. Fragment 1 presented lower values for the diversity indexes of Shannon-Wiener, Pielou and Jackknife; Higher basal area and number of individuals per hectare, better quality and stem health among tree individuals and better spatial distribution than fragment 2. Field data analysis allows to confirm that Fuzzy logic was effective in determining potential fragments for collection of forest seeds with higher degree of conservation, based on the determination of the richness of the fragments. Fragment 1 has greater richness, higher basal area, lower diversity, better quality and health of the stem, and better spatial distribution than fragment 2. The methodology can be adapted to other zones and different biomes of the planet.
