Abstract:

Terrestrial orchids represent a wide diversity of species that are characterized by an equally diverse range of life history attributes. Threatened and endangered species of terrestrial orchids have been identified on all continents where they occur and conservation plans have been developed for some species. Even though there is a considerable amount of information on the ecology of terrestrial orchids, few species have been studied in detail and most management plans focus on habitat conservation. In this paper, we consider the diversity of terrestrial orchids and summarize information on threatened and endangered species from a global perspective. We also describe approaches to the conservation and restoration of terrestrial orchids and develop the argument that much information is needed if we are to successfully conserve this diverse group of plant species.
