The objective of this study was to compare the richness, meeting frequency, species composition and termites’ feeding guilds in different reforestation in the Amazon area and between two classes away from native forest. We tested the hypothesis that attests to the richness, composition and quantity of species and meeting frequency against the termites’ guilds may be affected by the type or successional state in which the environment is. We also tested the hypothesis that the termites’ community is significantly nested, with one environment serving as the source to the other. We sampled the assembly of termites in five environments with different vegetation, including pastures with cattle activity, monospecific Tectona grandis reforestation, and Ficus spp., brushwood and native forest. We did not detect the native forest distance effect on termites’ wealth and frequency meeting. In contrast, wealth, on average, was higher in native forest and lowest in brushwood. The mean frequency of termites’ meetings per environment was higher in native forest and lower in brushwood. The community is nested and the environments whit higher contributions in species richness for other environments are native forest and fig reforestation. For guilds richness, we note that the species that consume humus present richest environments. The intermediates differ between environments. The reapers were among the rarest environments, being absent in brushwood. As for the meeting frequency by the guild the species that consume humus differ in their proportions between environments, along with the intermediates. We conclude that the termite fauna return of a degraded environment as pasture to a natural environment as the native forest, is closer to environment natural conditions in the teak reforestation and fig reforestation, since the return to be greater functionality and more the next guild proportionalities in reforestation than in brushwood.
