Where are they and why?

The anthropogenic effects on wild orchids through MAXENT.
A presentation I gave in March 2016 to explain part of my dissertation.
This is a project that looks at how people affect the distributions of orchids in Xishuangbanna, China.
None of it would have been possible without the Two Dragons Garden Project, which is supported by the British Council, Xishuangbanna Tropical Botanical Garden, the Chinese Union of Botanical Gardens, the Confucius Institute, Treborth Botanic Garden, Bangor University, the Royal Botanic Garden Edingurgh, and Botanic Gardens Conservation International.
