Composition and diversity of tree vegetation, an instrument of tourism management, case: Lake Lagrio recreational ecological park (Perla) Sucumbíos-Ecuador.

The present study focused on determining the composition and diversity of arboreal vegetation for tourism promotion purposes and generate technical information in which the attributes of the forest resource to carry out this activity are sustained. Ten transects of 10 x 50 m were established, data of all individuals e» 10 cm in diameter were taken at breast height, and forest wealth, structural characteristics, importance value indices and diversity indices were determined. An approximate of 672 individuals / ha was recorded. grouped into 25 families, 37 genera and 42 species. The richest families are Meliacea, Lauracea, Mimosaceae. The forest presents a basal area of 39,4 m2 / ha; and a volume of 255,3 m3 / ha. The species with the highest importance value index are Guarea kunthiana, Inga spp, Nectandra guadaripo, Pourouma minor, Chrysophyllum argenteum, the upper stratum is represented by Pourouma minor, Vochysia ferruginea and Dussia lehmannii the stratum co-dominated by Guarea kunthiana, Miconia sp. Nectandra guadaripo and the stratum suppressed by Simarouba amara, Virola elongata. The trees are grouped into 11 diametric classes, of which the first three cover the largest number of individuals (84.5%). The diametric distribution is formed by young and thin individuals. According to the attributes and structural characteristics of the forest, it was determined that the study area has exceptional features, capable of motivating on its own or in conjunction with other contiguous attractions, a current or potential current of national or foreign visitors.
