Rhododendron arboreum is an ecologically and economically important forest tree species in high altitude forests. In the Himalayan region of Northeast India, R. arboreum is extensively harvested as a source of fuelwood while selected forest stands have been set aside as protected forests by tribal groups resulting in a mosaic of harvested and protected forests. I assessed the genetic structure of R. arboreum in these forests using microsatellite markers that were originally developed for R. mettemichii . Out of eight pairs of primers evaluated, three primer pairs showed reliable amplification and polymorphism in R. arboreum . These three primer pairs or loci (RM1D1, RM2D2, and RM9D6) were used in assessing the genetic structure of R. arboreum in protected and harvested forests in the Eastern Himalayan region of Northeast India. Leaf samples collected from over 125 trees in five populations of R. arboreum representing two protected and three harvested forests, 35 different alleles were detected at three loci, with an average of 11.66 alleles per locus. There were no significant differences in number of alleles between populations. Over all populations, the mean observed and expected heterozygosity values were 0.801 and 0.804, respectively. A total of five private alleles were detected in two of the five populations (Pipraw Jang disturbed and Falokchar Mukto disturbed), suggesting private alleles are confined to harvested populations. The values of population differentiation (Fst) ranged between 0.015 and 0.057 with a corresponding gene flow (Nm) values of 15.8 and 4.1 respectively suggesting moderate levels of gene flow among populations. Population differentiation showed a significant correlation with the geographic distance. The high level of heterozygosity suggests a predominantly outcrossing mating system in R. arboreum . Although the level of population differentiation is low, the significant correlation between population differentiation (Fst) and geographic distance within a short distance of about 5 km is striking. In order to capture and maintain maximum genetic diversity, representative populations of R. arboreum distributed throughout its geographic distribution range should be conserved. These populations may serve as a seed source for regeneration of adjacent harvested forests. Further studies are needed to gain insights into the source of these private alleles as well as average distance of gene flow to determine the optimal distance for establishing protected populations of R. arboreum.

The conservation planning of Rhododendrons of Eastern Himalaya was underkaen by Sudipto Chatterjee who received the Whitley Associate Award in 2009 from Whitley Fund for Nature, UK. The study could contribute to Redlisting of Rhododendrons of Eastern Himalaya by the Botanic Garden Conservation International UK. The planning process involved expertise from IUCN Nepal, Botanical Survey of India, GB Pant Institute of Himalayan Ecology and Development, State Forests Departments in Sikkim and Arunachal Pradesh, University of Delhi, WWF-India, State Forest Research Institute, Arunachal Pradesh and Kunming Institute of Botany, China. State level consultation was held at North East Regional Institute of Science and Technology, Nirjuli, Arunachal Pradesh. Part of the study was conducted by Sudipto Chatterjee at Royal Botanical Garden, Kew, London, during International Course for Plant Conservation Techniques in 2001. Prof H.Y Mohan Ram, Fellow of Indian National Science Academy (INSA), New Delhi delivered the key note address during the Conservation Planning.

North-East India, comprising the seven contiguous states around Assam, the principal state of the region, is a relatively unknown, yet very fascinating region. The forest clad peripheral mountains, home to indigenous peoples like the Nagas, Mizos and the Khasis, the densely populated Brahmaputra valley with its lush green tea gardens and the golden rice fields, the moderately populated hill regions and plateaus, and the sparsely inhabited Himalayas, form a unique mosaic of natural and cultural landscapes and human interactions, with unparalleled diversity. The book provides a glimpse into the region’s past and gives a comprehensive picture of its physical environment, people, resources and its economy. The physical environment takes into account not only the structural base of the region, its physical characteristics and natural vegetation but also offers an impression of the region’s biodiversity and the measures undertaken to preserve it. The people of the region, especially the indigenous population, inhabiting contrasting environments and speaking a variety of regional and local dialects, have received special attention, bringing into focus the role of migration that has influenced the traditional societies, for centuries. The book acquaints the readers with spatial distribution, life style and culture of the indigenous people, outlining the unique features of each tribe. The economy of the region, depending originally on primitive farming and cottage industries, like silkworm rearing, but now greatly transformed with the emergence of modern industries, power resources and expanding trade, is reviewed based on authentic data and actual field observations. The epilogue, the last chapter in the book, summarizes the authors’ perception of the region and its future.

The genus Rhododendron is acclaimed in horticulture for its most elegant, bell-shaped flowers of varied colours. In India, Rhododendron species are found in the Himalayas from Kashmir to Arunachal Pradesh and in the forested mountain tracts of N.E. Indian States. The interest in the Himalayan Rhododendrons began with the discovery of the red flowered R. arboreum in Kashmir in the year 1796 and introduction of its seeds into the English gardens in 1827. J.D. Hooker's travels in Sikkim between 1848-1850 revealed the hidden rhododendron treasure. Following this, series of botanical explorations were undertaken in the Eastern Himalayan region by noted botanists and plant collectors from England bringing forth the richness and species diversity of the genus. Himalayan Rhododendrons have contributed a great deal in developing many horticulturally appealing clones and have ensured their importance in a multi-million dollar horticulture trade in the West at par with roses and orchids. In India, the species in the Western Himalaya and Sikkim are better known, while the species that inhabit the densely forested inaccessible mountains in Arunachal Pradesh and other N.E. Indian states largely remained less known or even unknown. Thus there has been no comprehensive account of all the species of the genus in the country leaving a wide gap to know the Indian rhododendrons wholly and from a single source. Hence this book. The book provides detailed taxonomic treatment of the genus in India with workable keys to the subgenera, different sections, sub-sections, species and sub-specific taxa with botanical descriptions. Colour photographs for many species, line drawings for about 20 species, distribution maps for all the species are provided to enhance the scientific value of this book as a Reference Manual for the use of botanists, teachers, students, foresters, nature lovers and conservationists. In short this book is the need of the hour for planning appropriate scientific conversation measures to safeguard the rhododendron species and their sites from further destruction, depletion and possible extinction.
