Abstract:Arundillaria mating is a temperate bamboo having durable culms with multipurpose application. From ecological point of view, it has been described as a rare and endemic species which is distributed in the Himalayan centre of the world's biodiversity hotspots, The largest habitat of this bamboo species was identified in the Jang area of Tawang district of Arunachal Pradesh, lndia covering an area of about 3170 ha along an altitudinal gradient of 2400-3600 m a.s.!. Both edaphic and climaticfactors had signi ficant role on the distribution and growth of A. malillg. The microclimatic .factors preferred by A. mating which was worked oUl from this study include 1894-1996 mm annual rainfall, 20500-88400 lux light intensity. 5-j j °C air temperature. 1-5 km h·1 wind velocity, 2-8 °C soil temperature, 40-52 per cent soil moisture content, 54-65 per cent water holding capacity, 0.20-0,40 g em'] bulk density. 5.26-5.46 soil pH. 0.41-0.88 per cent soil nitrogen, 6·8.82 /lg g.1 available phosphorus. 0,052 per cent potassium and 6.36-9.93 per cent soil organic carbon,
