The Nangunhe Nature Reserve in Southwest Yunnan has been the last stronghold of the Yunnan lar gibbon. During a survey from 4 to 18 November 2007, no evidence of the survival of the Yunnan lar gibbon could be found and the scientists of this survey tentatively concluded the lar gibbon has become extinct in China, and the Yunnan subspecies globally. The 2008
IUCN Red List of Threatened Species has listed this subspecies as
data deficient "as its taxonomic and geographic limits are not well defined, but population sizes are by all accounts critical, and the remaining populations are near extinction." ==References==
