Thale Noi Non-Hunting Area hosts several orchid species that are protected by the Convention on International Trade in Endangered Species ( CITES ) due to historical over-exploitation for their aesthetic appeal, including Finlayson s Cymbidium ( " Cymbidium finlaysonianum " ) and the Aloe-leafed Cymbidium ( " Cymbidium aloifolium " ) both found on limestone outcrops within the reserve.
