Ecosourcing is the practice of growing native plants from local seeds. The idea is to produce plants that are highly suitable to the very narrow local environment in which they were harvested and propagated. As a conservationist, you will appreciate that the great benefit of ecosourcing is its ability to maintain the widest possible diversity within species, rather than enabling a more generic overlay to take hold within a plant species. Any unique characteristics that belong to local variants of plant life will be maintained when ecosourcing is practised and promoted.
