Dr. Howard and his wife Dr Deb – an English couple – have joined 14 expeditions to Vietnamese caves over the past 20 years and contributed to UNESCO’s recognition of Phong Nha-Ke Bang as a World Natural Heritage Site. They have spend most of their lifetime on cave expeditions. Howards has been exploring caves in the UK and Europe since he was 15.

Being attracted by the limestone karst mountains were, so they decided to go to Asia in 1990. The couple patiently sought the cooperation of regional agencies and organizations. Finally, they got some help from Hanoi General University, now named Hanoi National University, to make their trip to Vietnam possible. After that, they focused on exploring destinations in Vietnam. Being a member of the British Cave Research Association, Howard has led an expedition team on trips to Vietnam since 1990. The team has cooperated with Hanoi National University to conduct 14 journeys to different localities in Vietnam, including Quang Binh, Nghe An, Thanh Hoa, Hoa Binh, Lang Son, Cao Bang and Ha Giang. It has discovered nearly 300km of caves in Vietnam.
The team of this couple found Khe Ry in Quang Binh Province in 1997, the world’s longest underground cave. In 2009, it discovered Son Doong, the world’s biggest cave, also in Quang Binh. Their reports have contributed to Phong Nha-Ke Bang National Park being recognized by UNESCO as a World Natural Heritage Site.
According to Dr Howard,Vietnamhas one of the world’s most impressive limestone areas. Clearly, many caves situated in Ke Bang Mountain have yet to be found, Howard and his team hope to continue their search with the cooperation of the Vietnam National University, Hanoi.
Besides, the couple has helped call on the international community to pay attention to the protection ofVietnam’s nature and environment. They have also shown a number of well-known film crews aroundVietnam. Through the films, the world has become more aware of Vietnam’s beauty and the world’s biggest cave, Son Doong, in Quang Binh
Their most recent visit to Vietnam is from March 3 to April 26, 2012, along with their team and some film crews to make documentaries about caves in Quang Binh. In 2010, the British expedition team took the film crews and reporters from Kyodo, NHK, BBC, and National Geographic among others, to Vietnam to shoot films about Son Doong Cave. In 2011, they invited representatives from the BBC to Quang Binh to make another film about Son Doong Cave.





Tien Son Grotto is more than 980m long. Going into the cave for about 400m, visitors will see an abyss, about 10m deep. Then comes another part of the cave, about 500m long is rather dangerous for walking. At present, nearly 400m of the cave have been installed with lighting system to make it safe for visitors.
Preliminary faunal surveys have documented a total of 735 vertebrate species,including 127 threatened species,91 of them listed in the Vietnam Red Data Book 18 species listed in the IUCN Red List of Threatened Species. In particular among of the total of 41 animal endemic species 30 species are endemic to Vietnam and 40 species are endemic to Annamite Mountain Range (Vietnam and Laos).




The limestone forest ecosystem at Phong Nha-Ke Bang supports a high diversity of plant and animal species. Of perhaps the greatest conservation significance are several species found at the site that are endemic to this part of central Vietnam and Laos. These include Sooty Babbler Stachyris herbeti, a globally near-threatened species that went unrecorded between its discovery in Laos in the 1920s and its rediscovery at the site in 1994. Phong Nha-Ke Bang also supports populations of two endemic primates, Annamese Leaf Monkey Trachypithecus hatinhensis, and an all-black form referred to as Black Leaf Monkey T. ebenus.
