Conservation of ApesThe goal of this program is to reduce threats to apes in their natural habitats. It focuses specifically on the protection of ape populations and habitats in priority landscapes. Prioritization is based on the size of the habitat, size and density of the ape population, the number and species and level of threat, the presence of effective conservation efforts, and the existence of supportive institutions and legislative frameworks.
Arcus investments follow three guiding principles: Support goes to initiatives that are long-term, holistic, and collaborative. The current conservation strategy has identified 25 priority landscapes: 12 in pristine areas , 11 in frontier areas , and 2 isolated area .
While support is available for short-term projects to mitigate sudden threats or meet urgent ape protection needs, the majority of Arcus conservation investments are designed to support: Organizations which take a holistic approach, and which focus on long-term engagement and collaboration; collaborative efforts with influential policy-level partners—including governments, multinational, and private sector organizations—to analyze socio-economic factors and link livelihoods and development initiatives with conservation goals; capacity building and investment in organizations and leaders to meet locally appropriate needs and priorities and to monitor and assess the impact of their work.
