Cross-bred into extinction?


The endangered golden langur (trachypithecus geei), which is native to Bhutan and some parts of the neighbouring Indian state of Assam, could be under threat of extinction from crossbreeding with the capped langur, according to a Bhutanese researcher.

"The crossbred offsprings are very fertile and can produce further offsprings easily and that could erase the golden langur species," said Dr Tashi Wangchuk who has studied the conservation of golden and capped langurs in Bhutan. "The golden and capped langurs hybridise naturally in areas between the Dunmang tshachu in Zhemgang and Riotala (near Kartigangchu) in Trongsa."
