Biological corridors are fundamental strategies for biodiversity conservation in fragmented landscapes. However, few evidence exist respecting their functionality or the population viability of its species on long term especially for the tropics. We performed a theoretical-descriptive approach to determine mammals’ risk of extinction based on three main parameters: species vulnerability and area and habitat requirements, each one of these categories were classified in levels of high, medium and low. For large mammals there is a high probability of extinction, while for medium and small mammals there is a low probability of extinction and a high probability of permanence of viable populations with high habitat availability.
