The Shan plateau of Myanmar has extensive karst stretching over an area of 500 km x 300 km. Due to its isolated location a systematical exploration for karst and caves is only done since 2009 resulting in ten expeditions surveying 37 km of passages. The areas of Ywangan, Hopon and Pinlaung were systematically investigated while for the areas of Lashio and Kayah state an initial assessment was done. The longest cave in Myanmar is Khauk Khaung (Stone cave) in Ywangan with 4790 m length while Mai Lone Kho is the deepest with -160 m The identified karst objects are registered in a cave data base containing 600 items. It is publicly shared under a CC license as base for further research. One application used from Flora Fauna International (FFI) is to identify karst based biodiversity areas (KBA) for conversation within the IUCN standards. The project collected 251 specimens.
