Ecosystem restoration versus reclamation : the value of
Recent public demands for the preservation of biological diversity are often using this concept as a surrogate for the value of rare species, nature preserves, and wilderness. But diversity per se can have value in intensively managed and artificial ecosystems as well, suggesting that maybe we should practice ecosystem "restoration" more than just land reclamation". If a plant community is to
