PS values of COT-140.66 Mg * ha-1 were obtained; COS was evaluated in intervened and non-intervened areas at (0-30, 30-60, 60-90) cm deep; that showed the conversion of forest to grass, SOC decreased and presented highly significant differences from 784 (Mg ha-1) to 556 (Mg ha-1), biodiversity established the dominance of Miconia sp, Miconia pseudocentrophora and Andean Myrsine; the Simpson 0.75, Shannon 1,53 and Margaleff 5.67 indices, determine a high diversity of species; the RS showed values of 0.47m3/s for agricultural flow, 0.78m3/s for ecological flow and 0.003m3/s for human consumption flow of which 165 users are supplied; The AS/RS relationship indicates degradation processes in the FES, whichresults as an indicator for the implementation of Andean eyebrow forest management policies. |
