The effect of the fragmentation on the composition and structure of the ecosystem was determined, using as indicators the Orchidaceae and Bromeliácea families in the mist forest of the territory of the peasant community of Granada, Amazonas 2017 in wet and dry seasons, whose question, which Is the effect of fragmentation on the composition and structure of the ecosystem, using as indicators the Orchidaceae and Bromeliácea families in the mist forest of the territory of the peasant community of Granada, Amazonas 2017?. The study area was divided into two strata degraded area (Ar.No. Dgra) and non-degraded area (Ar. Degra) performing whittaker methodologies and variable transects in 40 transects resulting in (Ar. No. Dgra) 17 352 individuals representing 80.70% and in (Ar. Degra) only resulted in 4149 individuals representing 19.30% with respect to abundance, these data explain loss of 13 203 individuals which determines that in degraded area they are absent or have disappeared 76.09 % of its specimens plus diversity values expressed by Shannon (H ') and Simpson (1-D) show a quite significant difference between non-degraded area with H' = 5.28 bits / ind and (1-D) = 0.99 probits / ind and degraded area H '= 2.41 bits / ind and (1-D) = 0.78 probits / ind, indicating that there is a significant effect that explains the absence or loss of species by stratum evaluated, where it is estimated that between strata differ from a value of 2.87 bits / ind, indicate There is a loss of abundance and species richness to 45.6% in the study area with respect to the original status of each habitat.
