Integrated conservation of Florida Orchidaceae in the genera Habenaria and Spiranthes: Model orchid conservation systems for the Americas.

摘要

Rapid loss of native orchid habitat throughout ecologically-important areas (e.g., Florida) has prompted researchers to develop appropriate conservation systems for the preservation and recovery of native orchid species. These conservation systems must incorporate more than habitat preservation and plant propagation, they must integrate the study of native orchid ecology, mycology, propagation, pollination biology, and population genetic diversity in a combined conservation effort. The current studies examine the ecology and demography, mycology, asymbiotic and symbiotic propagation, pollination biology, and population genetic diversity of orchids in the genera Habenaria and Spiranthes. The specific Florida native orchid included in this study are: Habenaria macroceratitis, Spiranthes floridana, S. brevilabris, and the Deep South race of S. cernua. The application of integrated conservation to the preservation of these native orchids is discussed, and integrated conservation steps are proposed that will help ensure the long-term population viability of these species. Furthermore, these integrated conservation systems could be applicable outside the United States and Florida.
