Loss of wildlife, encroachment on wild lands and conflicts between protected areas and neighbouring communities continue to threaten the integrity of protected areas (PAs) in Uganda. To increase support from local communities and ensure long-term sustainability for Uganda's PAs, a policy of community-based conservation was introduced in 1988 as a management approach in seven PAs. The effectiveness of the community-based approach for reducing threats was compared to conventional PA management by conducting a threat reduction assessment at 16 PAs, seven with community-based approaches and nine without. Additional data collected using document reviews, interviews with government officials, and surveys of PA wardens were compared with the threat reduction assessments. Twenty-three primary threats were identified at PAs. Local game poaching was the most common threat. The threat reduction assessment indices of community-based PAs (mean=49.0±12) were not significantly different from those of conventional PAs (mean=37.96±21.6). Some specific threats, such as bush burning, logging, encroachment and unclear boundaries, seemed to be better mitigated at community-based PAs. Management approaches at all PAs mitigated fewer than half of the identified threats. Management approaches are needed that directly target PA threats, go beyond PA boundaries by involving additional government departments, link people's livelihoods to conservation efforts and strengthen PA institutions.
