Systematic, science-based conservation planning is a hallmark of the Conservancy. For biodiversity to thrive, habitats need to be protected, enhanced, or restored not just in the still wild places on the planet but also where people live and make their livelihoods. 

Multi-disciplinary planning can help elucidate where the highest priority places are and what needs to happen there – and inform tradeoffs between conservation and other societal values.
