That's a reason I suggested Orchid Societies have the "licence" as I know in my Society there is a very strong climate of conservation. Some in our group do have permission from the Government to rescue threatened species and these are cultivated and shared within the Society with funds from the sales going towards conservation projects.
Wholesale pilfering should be stopped at all costs.
