Surv. India: 102 (Part 1-2) : 1-5, 2004 A NOTE ON THE PRIMATES OF TAWANG DISTRICT, ARUNACHAL PRADESH J R B ALFRED, A. MURMu, P. C. MAZUMDER AND S. CHAUDHURI Zoological Survey of India, M-Block, New Alipore, Kolkata-700 053 INTRODUCTION Arunachal Pradesh, the land of dawn-lit mountains with all its forest and wildlife resources sequesters at the farthest point of the north-east region of the country. Tawang, one of the ten districts, appearing just like a speak of the vast stretch of its state's terrain is situated at 90°45' to 92°15' N latitude and 27°22' to 27°45' E longitude with an area of 2085 sq. km. Tawang, the westernmost district of the state; two-third of the area is of high mountaneous region bounded by China (Tibet) in the north, Bhutan in the south-west and West Kameng district (AP) on the east accommodates only 28,287 human population (2001 census). The climate of the ~istrict is of temperate nature, moderate in summer and remain much below the freezing point during the winter. Rainfall in the district reasonably high during monsoon (May to September). Steep high mountaneous ranges run elsewhere in the plummer down to the green valleys where they together with other tributaries finally meet the Brahmaputra river. Forest is the main economy in the state, but Tawang depends mainly on agriculture and tourists. The district has only one social forestry division with two forest ranges and five non-account:beats. There is no Reserve Forest and no Protected Forest in the district. Recently two Anchal Reserve Forests have been proposed comprising of 405 hec. of land. No wonder the state has been a dream of naturalists. Many a number of expeditions, surveys have been undertaken by the naturalists of national and intematiQnallevels. But possibly, no attempt on primates survey have been made in the district of Tawang. Therefore, keeping the view in mind, a preliminary survey to the montane forests and river valleys in the south and north-west parts of the district has been carried out during the month of May, 2002. The monkey groups that were encountered during the survey was Assamese macaque, Macaca assamensis. The other primate species which occur at Tawang is capped langur, Trachypithecus pileatus, which inhabits in the inaccessible terrain and rarely come in the villages or roadside forests at lower elevation. They are shy but true arboreal in the district. The "Pere Davis" macaque, Macaca thibetana, endemic to China to E. Tibet, Szechwan to Kwangtung ( Pocock, 1939 ) and the Stump tailed macaque, Macaca a rcto ide s , reported to occur at Tawang, could not be located m the present survey even inquires from local people and Forest Department not confirmed its presence in the study area. 2 RECORDS OF THE ZOOLOGICAL SURVEY OF INDIA However, the occurence of Pere Davis macaque can not be ruled out at this stage till a detail investigation is made. The characteristic physical appearance of the Assamese macaque at Tawang was close to description of other authors (Pocock, 1939; Roonwal and Mohnot, 1977). The monkeys were bigger in size and dark coat colour at Tawang as compared to individuals seen at lower elevation might have confused the observers reporting the possible occurence of a new species. A perusal of literature revealed that Macaca assamensis inhabits the foothills of the Himalayas and adjoining mountain ranges in south Asia (Hill and Bernstein, 1969; Fooden, 1989). The Assamese macaque belonigs to sinica group of macaque together with Macaco sinica, Macaca radiata and Macaco thihetana (Fooden, 1982 ). The present survey revealed that Assamese macaque population is fairly common in the south and north-western parts of Tawang.
