Habitat fragmentation and degradations for agricultural and livestock activities is one of the principal factors in the reduction of their potential habitats and distribution. This also includes natural disasters such as wildfire (Bello 2004). Hunting is a major threat in some areas - especially in and around protected areas. Harvesting for cultural activities, and principally as a food source could influence their populations levels and behaviour (Reyna-Hurtado 2002). Another threat that has existed for a long time is their killing as a pest control in bean croplands (Méndez-Izquierdo and Bello-Gutiérrez 2005).
