Abstract

The study was developed with the objective of evaluating the effect of the altitudinal gradient on the structure and diversity of the tree community on Mount Unango, for this, where 3 strata were allocated with 25 plots each, all with 100m². After its development, it was found in strata1, 2 and 3, a total of 1919 tree individuals distributed in 33 species, 25 genera, and 16 botanical families. The families best represented in number of species were: Fabaceae, and Caesalpinaceae. The species Catunaregam obovata, Piliostigma thonningii, Syzygium guineense, Parinari curatellifolia, Cussonia arborea and Annona senegalensis were present in all altimetric strata at Unango Mount. The diversity was: 1,9, 2,6, and 1.8 respectively for strata 1, 2 and 3. Analytically there was a high similarity between the strata 1 and 2 studied with 50% in the Jaccard index (9 species in common), and lower similarity between strata 1 and 3 (1 species in common) with 25% of the index. The gradient studied presents a peak of diversity and richness at intermediate altitudes. And there was an abrupt transition in terms of the composition in the upper stratus (1040m), which presents most of its floristic composition with characteristics of the high mountain ecosystems.
