These traditions are based on maintain a mosaic of agricultural and natural local and indigenous knowledge and practice. areas as a biocultural heritage site with some Traditional ecological knowledge may be 1200 potato varieties, both cultivated and wild. defined as a cumulative body of knowledge, practice and belief, evolving by adaptive processes and handed down through generations by cultural transmission. It is experiential knowledge closely related to a way of life, multi‐generational, based on oral transmission rather than book learning, and hence different from science in a number of ways. Traditional knowledge does not always result in conservation, just as science does not always result in conservation. But there are a number of ways in which traditional knowledge and practice may lead to conservation outcomes. First, sacred groves and other sacred areas are protected through religious practice and Box 1.1 Figure Paakumshumwaau Biodiversity Reserve in James enforced by social rules.
