CITES
The convention for international trade in endangered species was originally and commendably set up to prevent the illegal trade in endangered species of animals.
Plants and especially orchids were included hurriedly, and possibly without to much rational thinking, the result is that it is is now illegal to import orchids without the proper CITES documentation, whilst this may stop plants from being collected from their habitat in the wild, it is doubtful that it protects them satisfactorily, and certainly makes it illegal for nurseries to mass produce them, which would probably reduce the illegal demand for wild collected plants, thus securing their continuance in two different ways, especially in areas of deforestation.  

The CITES rule precludes the movement of any orchid from one country to another  without a permit,   even  nursery grown  hybrids,    European Union  members are considered to be individual states of one country
