The Orchid Specialist Group is a global network of experts who volunteer their time and expertise to build a scientific and practical foundation for the conservation of orchids (Orchidaceae).

Orchidaceae are the largest family of flowering plants and they occur in a wide range of ecosystems and habitats. A charismatic group, many species are important in horticulture. Habitats of orchids are, however, threatened throughout the world, and the OSG is dedicated to their conservation and sustainable use.
