  author={Robert H. Horwich and Raju Das and Arnab Bose},
Abstract: The golden langur (Trachypithecus geei), which only became known to science in 1953, is endemic to western Assam, India, and southern Bhutan. The Indian population had been greatly depleted due to a fragmented range and the species was declining radically in 1997 with a pessimistic view for its future. The Golden Langur Conservation Project was begun in 1998 with the goal of protecting the golden langur within its entire Indian range. At the time of the project's initiation, the… 

Conservation Status of the Golden Langur Trachypithecus geei in Chakrashila Wildlife Sanctuary, Assam, India

The golden langur, Trachypithecus geei, is among the world’s 25 most endangered primates. It is endemic to India and Bhutan. Its distribution is limited to a small forest belt in western Assam in

Genetic Diversity and Structure among Isolated Populations of the Endangered Gees Golden Langur in Assam, India

The present study sequenced and analyzed around 500 bases of the mitochondrial DNA (mtDNA) hypervariable region-I from 59 fecal samples of wild langur collected from nine forest fragments to estimate the genetic diversity in the Indian population of golden langur and established that T. geei is monophyletic but revealed possible hybridization with capped langur, T. pileatus, in the wild.

Population abundance and distribution of the endangered golden langur (Trachypithecus geei, Khajuria 1956) in Bhutan

The population estimate of golden langurs in Bhutan is much lower than the current IUCN estimate of 4000 individuals for Bhutan, necessitating a reassessment of its current conservation status due to threats from road kills, electrocution, and development activities like road construction, hydropower, and electrical transmission lines.

The Emergence of an Endangered Species: Evolution and Phylogeny of the Trachypithecus geei of Bhutan

The hypothesis that rivers and mountains in Bhutan isolated a population of capped langurs that later speciated into the morphologically distinct T. geei is tested and reconstructed the evolutionary history of the langurs of Bhutan via molecular phylogenetic tools.

Primates of Bhutan and Observations of Hybrid Langurs

Overall, it would appear that primates have a secure future in Bhutan, as there are large areas of contiguous habitats for primates, and there is, besides, a good network of protected areas in the country.
