Ecological and Sociocultural Systems Create a Strong Foundation for Sustainable Wildlife Management in the Amazon

Tropical forests of the Amazon support exceptional biodiversity while sustaining the livelihoods, cultures, and food systems of Indigenous communities. In Loreto, Peru, hunting remains central to both subsistence and market economies, yet its sustainability depends on ecological dynamics and sociocultural systems that shape harvest behavior. Here, we evaluate the potential for sustainable wildlife management in the Maijuna–Kichwa Regional Conservation Area (MKRCA) by integrating a spatially explicit biodemographic model of hunting with a targeted review of Maijuna hunting practices, governance, and economic context. Using participatory mapping data from 19 hunters in the community of Sucusari, we parameterized a model to estimate species-specific depletion under current and projected hunting scenarios. Model results suggest that current harvest rates are largely sustainable, with localized depletion near settlements but relatively intact populations across the broader landscape, supported by access to remote hunting areas and nearby source populations. The literature review reveals that Maijuna sociocultural systems, including territorial hunting norms, seasonal mobility, food-sharing practices, and species-specific taboos, may function as informal management institutions that distribute hunting pressure and limit overexploitation. Together, these findings suggest that both ecological conditions and sociocultural institutions in Sucusari are conducive to sustainable wildlife management if supported by adaptive co-management approaches. However, external pressures, particularly a proposed highway, may fragment existing source–sink dynamics and pose a significant risk to long-term sustainability.
