Knowledge of the conservation status of the habitats of animal species such as non-human primates is essential for their sustainable management and conservation. To better analyse the extent of threats and assess the conservation status of non-human primates in Togo’s forest zone and ecological zone II, an analysis of forest cover dynamics in these two zones was carried out using digital processing and interpretation of Landsat imagery from 1985, 2000 and 2020. Software such as Envi 5.1 and Qgis version 3.34 were used for this purpose. Analysis of the spatio-temporal dynamics of the forest cover revealed a high rate of deforestation, estimated at 0.7%, reflecting a worrying level of degradation and disturbance of the habitats of all the non-human primates that depend on the ecosystems in the study area. Numerous pressures are thus threatening the survival of non-human primate populations in the study area.Poaching comes first, followed by habitat destruction and disturbance caused by human activities such as agriculture and logging. The community of non-human primates is therefore in real danger of extinction in Togo if appropriate action is not taken in time to preserve them. An effective conservation and sustainable management strategy for the network of protected areas in the study area needs to be updated and implemented.
