This researchaimed to evaluate areas disturbed by anthropic activitiesand allowed to establish an ecological restoration plan withnative species of the secondary forest of the EcuadorianAmazon, in the Community of San Pedro “Lisan Wasi”,Parish Tarquí, Canton of Pastaza, was carried out a floristicinventory, the indices of value of ecological importanceand extended ecological importance were determined.In addition, the specific wealth index of Menhinick, andMargalef, of Shannon-Weaner equity, Simpson’s dominanceto know the diversity of the vegetation was obtaided. Aswell as the Jaccard, Sorensen Indice and the hierarchicalconglomerate. The degree of disturbance of the area wasevaluated through indicators of changes in the ecosystem, asa result a total of 33 families were identified, and 74 speciesbelonging mainly to the tree, shrub and herbaceous stratum.Representative species were Bromeliaceae catopsis,Cedrela odorata, Cecropia peltata, Persea americana,Schizolobium parahybum. The most representativefamilies, in this order: Fabaceae, Aracaceae, Poaceae,Rutaceae and Melastomataceae. Index values showed thatthere is a large number of species that the community hasdominant species and therefore the diversity is greater;there was no equitable formation and all species are notabundant. The degree of disturbance identified was due toalteration to the composition of species and alteration tothe structure, the diagnosis allowed to apply the techniquesof ecological restoration for the improvement of the studyarea, through the transplantation with native species in anarea of 0.24 ha, in the affected areas. |
