Ashish Paul，M. L. Khan*，A. Arunachalam和K.印度阿鲁纳查兰是世界上12个拥有巨大多样性的国家之一，根据物种稀有性和特有性，有两个热点-西高止山脉和东喜马拉雅山脉。喜马拉雅东部的阿鲁纳恰尔邦是全球200个重要生态区之一。该邦拥有印度近50%的开花植物物种。杜鹃花是阿鲁纳恰尔喜马拉雅地区冷温带、亚高山和高山地带沿着的优势种。杜鹃花是杜鹃花科最大的属之一，生长于高海拔地区，具有重要的生态意义和经济价值。约98%的印度物种分布在喜马拉雅地区，其中85%分布在阿鲁纳恰尔喜马拉雅地区。它具有审美价值、神圣价值、芳香价值、药用价值和薪材价值。由于人类的干扰，阿鲁纳恰尔喜马拉雅山的杜鹃花自然种群正在逐渐减少。西部阿鲁纳恰尔邦的杜鹃面临的主要威胁是当地人砍伐森林和不可持续地提取木柴。杜鹃属稀有、濒危和受威胁植物，如果不采取适当的管理和保护措施，可能在不久的将来从生物群中消失。各种原地以及迁地措施，如建立树木园，禁猎区，公园和保护林，通过社区管理，植物园和体外研究程序的保护区，以保护该物种的后代。此外，人民的意识和参与是成功保护的保证。
Ashish Paul, M. L. Khan*, A. Arunachalam and K. Aru nachalam India is one of the 12 mega diversity countries in the world having two hotspots – the Western Ghats and the Eastern Himalayas, based on species rarity and endemism. Arunachal Pradesh in the Eastern Himalaya is among the 200 globally important ecoregions. The state harbours nearly 50% of the total flowering plant species in India. Rhododen drons form the dominating species all along the cool temperate, subalpine and alpine zones in the Arunachal Himalaya. Rhododendron is one of the largest genus of the Ericaceae family, occurring in the higher altitudes having ecological significance and economic importance in addition to its graceful flowers. About 98% of the Indian species is found in the Himalayan region, among which 85% is found in the Arunachal Himalaya. It has ae s-thetic, sacred, aromatic, medicinal and fuelwood values. Due to human interference the natural populations of rhododendrons in the Arunachal Himalaya are gradually diminishing. Major threats to rhododendrons in western Arunachal Pradesh are deforestation and unsustainable extraction of firewood by the local people. Rhododendrons which are classified as rare, endangered and threatened may be wiped out in near future from the biota, if proper management and conservation initiatives are not taken up. Various in situ as well as ex situ measures like establishment of arboretums, sanct uaries, parks and reserve forests, protected areas through community management, botanical gardens and in vitro research procedures are prescribed to conserve this species for posterity. Moreover, awareness and participation of and by the people is warrant ed for successful conserv ation.
