Few conservation projects and sites are effectively measuring the impacts of their interventions in order to guide decision-making for adaptive management and optimize resource allocation. We showcase an integrated biomonitoring program in five Congobasin countries that aims at assessing conservation impact by simultaneously collecting data on wildlife, management interventions and socioeconomic activities, applying innovative approaches such as distance based camera trap sampling, automated detection of elusive forest species and building capacity through a multi-stakeholder engagement. We provide results for regional and site-specific analysis, including from several World Heritage sites, such as the Tri-National de la Sangha situated in between Cameroon, Central African Republic and Republic of Congo and for Salonga, Democratic Republic of Congo. New innovative methodologies applied and the challenges and opportunities that come with these will be discussed.
