Composición florística, estructura y endemismo del componente leñoso en una parcela permanente en el bosque montano de la parroquia Santiago, provincia de Loja, Ecuador

The research was carried out to determine the floristic composition, structure and endemism of the woody component of El Sayo the protective forest in Santiago parish, canton and province of Loja, from May 2020 to February 2021. A permanent plot of one hectare (10 000 m2), divided into 25 subplots of 400 m2 (20m x 20 m) was installed, all trees ≥ 5 cm diameter D1.30 m were invented and the variables diameter and height were measured. In the permanent plot a transect of 10 m x 100 m was nested, the trees were recorded ≥ 5 cm of D1.30 m in the distances X and Y, for the structural profiles of the forest. Floristic diversity was determined and structural parameters calculated. For endemism, a comparative analysis was carried out with the Red Book of Endemic Plants of Ecuador. 1793 individuals belonging to 68 species within 42 genera in 33 families were determined. The forest had a basal area of 24.71 m2/ha and volume of 173.52 m3/ha. The most ecologically important species are: Weinmannia latifolia, Ilex myricoides and Clusia alata. The largest number of individuals are grouped into the first three diametric classes, reflecting an inverted "J" indicating that it is a recovering young forest. Shannon's index with a value of 3.39 shows that the forest has an average uniformity of the importance values of all species in the sample. In addition, seven endemic species were identified. Keywords: Montane forest, permanent plot, structural parameters, floristic composition, diametric structure, structural profiles and endemism.
