The biodiversity crisis threatens one million species with extinction and jeopardizes the ecosystems on which over half of global GDP depends. Increasingly, efforts to conserve and restore biodiversity are made through distributed efforts, from contractor programs to remove invasive species to smallholder landowners restoring habitats. Because these activities are geographically dispersed and difficult to observe directly, obtaining reliable information about what is happening on the ground can be costly. This raises a central question: where, when, and how should we intervene to obtain the information that matters most? With examples from managing invasive Burmese pythons in Florida and monitoring for biodiversity credits in Kenya, we’ll discuss how active learning, sequential inference, and incentive design can help focus limited resources on the information most consequential for downstream decisions.
