Evaluate the effectiveness of management actions in protected areas of the Yavari Samiria Great Landscape is essential for the conservation and sustainable use of biodiversity in the region. The objective of this work was to assess the use of occupancy models as tools for monitoring the effectiveness of the sustainable use of some species by surrounding communities. Between February and May of 2015, at Tamshiyacu Tahuayo Communal Regional Conservation Area (ACRCTT), 84 grids of 1km², were established to evaluate the occupancy of Tapirus terrestris (Linnaeus), Tayassu pecari (Link), Pecari tajacu (Linnaeus), Mazama sp., Cuniculus paca (Linnaeus), Dasyprocta sp., Dasypus sp. and Cracidae vigors, through signals and trails in transects and camera traps stations. Single season-single species occupancy models with site covariates (CovS) were adjusted to assess the hunting effect. The occupancy estimated for ungulates was high (Ψ =0.95), except for T. pecari (Ψ = 0.13), with no effect of site covariates assessed (Sigβ(CovS) > 0.05). This indicates that hunting pressure is not affecting the large species evaluated at ACRCTT. It was not possible to adjust models for small species. The accuracy of these estimates indicates that the use of occupancy is a confident indicator for the development of a monitoring program of large species at ACRCTT.
