Orchid Conservation : Making the links - The 5th International Congress on Orchid Conservation follows on from the successful congresses held in Perth (Western Australia) in 2001, Sarasota (Florida) in 2004, San José (Costa Rica) in 2007 and Hluboka (Czech Republic) in 2010. The orchid family is the largest family of flowering plants, and many species rely on a complex set of interactions for their survival. Their seeds cannot germinate without a relationship with a fungus and many have very specific pollinators. In a changing world, conserving orchids presents huge challenges as not all of the interactions will be affected in the same way by global change, habitat degradation etc. For this reason, we have decided to make «Ochid Conservation – making the links » the theme of the Congress. We expect that more than one hundred experts from around the world will attend the Congress, and with this gathering of expertise, we will be able to make some real progress towards the goal of conserving the orchids of the world.
