National Bamboo Mission envisages bamboo plantations over more than 1.7 ha which will need more than 7 crore plants. It is not enough to rely upon seedlings alone to meet this requirement and several organizations have started experimenting propagation by vegetative methods. These experiments have not finally concluded, but trends noticed in them can be predicted to some extent. Besides new techniques and machinery have also to be evaluated. Basing on these trends of bamboo have also to the evaluated. Basing on these trends seven bamboo species which include Bambusa balcooa, B. bambos, B. nutans etc. have been identified for pan Indian large scale plantations while 8 other species which include Dendrocalamus asper, Phylostachys pubescens, Guadua angustifolia etc. can be tried for regional plantation.

Populus ciliata and Populus gamblei are the two common poplars seen in Arunachal Pradesh. Their natural regeneration over the sub-tropical and temperate forests are very good. They come up well on exposed freshly turned soils, land slips, etc. They can be easily raised vegetatively by using branch cuttings and ischolar_main suckers quick to establish, fast growing and profusely coppicing. All these characters suggests suitability in agroforestry, soil conservation and jhum reclamation work in Arunachal Pradesh for which there is a vast scope in the State.- Study of Bamboos Through Establishment of Bambusetum in Arunachal Pradesh

The establishment of bambusetum at the Van Vigyan Kendra has triggered research on bamboos. Though a large number of bamboos were planted initially, many of them died due to wild animal damages and unfavourable climatic conditions for high altitude bamboos. The bambusetum could supply regularly rhizomes and planting stock to different aggencies. It will be worthwhile to create more such bambusetum covering different climatic zones. It is all the more essential for the high altitude bamboos. The bambusetum could also act as refuge for rare and endangered species of bamboos. Further observations could yield valuable results which could assist in better management and economy of bamboos.- Amentotaxus (Taxaceaf)-A Rare Gymnosperm from Arunachal Pradesh

The anatomical studies on Bauhinia retusa Ham. have been carried out with particular reference to gum exudation. The observations indicate that like other gum yielding trees gum canals either normal or traumatle or gum cysts are not present in this species but the vessels near the cambium are filled with gum due to wounding and the gum exudes from these vessels in tears. The vessels formed during tbe year of rest are free from gummy deposits.- Distribution and Population Status of Embelia ribes Burm.

Field surveys were undertaken to various parts of India to study distribution and population status of Embelia ribes, a red listed medicinal plant of India, used in many Ayurveda preparations, which also forms an important NTFP. Although this species has been reported across the country, it was never seen in great abundance during the present study and was often restricted to clearings and forest paths in the evergreen and semi-evergreen forests. Variation in leaf size and shape as well as fruit size were also observed in E. ribes collected from different locations. There are differences in fruiting and non-fruiting plants with respect to floral structure.Keywords

Dampa Tiger Reserve (DTR) in Mizoram is an important biodiversity spot in northeast India with rich vegetation and floristic diversity that are well preserved. A study of the flora here revealed that the DTR not only shelters a good number of threatened plants but also harbours a large pool of important species which are directly beneficial to the fauna. It supports substantial number of species capable of contributing to the livelihood and health security of the surrounding community too. A proper understanding of these species will help in effective implementation of the management plan for this protected area.Keywords

Conservation of biodiversity, a growing concern today, faces multiple challenges. Although ecosystem approach has been recommended as a solution, conservation of threatened species is difficult as they are spread across the ecosystems and are often restricted to microhabitats. In this article, the importance of taxonomy, herbarium and field germplasm bank in conservation of threatened species is discussed. It is concluded that individually each of these measures has important role to play in conservation. They also complement each other in reversing the threat perspective of the species.Keywords

The extent of genetic diversity within a species is an important determinant of successful adaptation to adverse environmental conditions. Assessment of extent of genetic diversity/variability is also important to monitor genetic erosion within a species. In threatened plant species, genetic diversity assessment helps in selection of genetically diverse populations to enrich the genetically impoverished populations, thus minimizing the probability of genetic drift. Confirming taxonomic identity of threatened species, particularly those belonging to species complexes with dispute identity, is another essential task in the conservation of threatened species, which is best resolved through molecular approaches. The present study estimated the genetic variability within and among the populations of four threatened species, viz. Justicia beddomei (C.B. Clarke) Bennet (Acanthaceae), Embelia ribes Burm. f. (Myrsinaceae), Madhuca insignis (Radlk.) H.J. Lam (Sapotaceae) and Cycas beddomei Dyer (Cycadaceae) using Inter Simple Sequence Repeat (ISSR) and Simple Sequence Repeat (SSR) markers for selecting the genetically diverse populations. The phylogeny was analysed through ITS (nrDNA) and matK (cpDNA) sequences to confirm the species identity.
The phylogenetic analyses confirmed four distinct species of Justicia, which also revealed that J. beddomei and J. adhatoda were sister groups with a common ancestor showing rapid parallel speciation with J. gendarussa in one clade and J. betonica in another. Madhuca insignis with extremely small population in the Western Ghats (Karnataka to Kerala) might have undergone either extensive hybridization or incipient speciation. In case of Embelia species, a greater evolutionary closeness between E. subcoraceae and E. floribunda was revealed, while E. ribes had a distinct clad. Both ISSR and SSR markers distinguished various genotypes of Cycas beddomei.

Assigning threat status to a species is essential for prioritization of species under any conservation programme, and therefore, a pre-requisite for species conservation. In India, due to inadequate data, threat status has not been assigned to several plant species, although their population sizes are quite small and they are considered important from conservation point of view. Besides, there is a need for reassessment of threat status assigned by various agencies using updated data on population size, number of mature individuals, area of occupancy, and geographic extent of occurrence. This is crucial as the natural habitats as well as populations of such species are being affected by anthropogenic activities, exotic species invasion, and climate change. In the present study, we assessed the threat status of 59 selected plant species following the IUCN criteria (ver. 3.1). The species were selected after consultation with various experts throughout the country. Field surveys were carried out in various ecoregions of India to locate the species. Population size and number of mature individuals were enumerated following quadrat/plot-based sampling. The exogenous and endogenous factors leading to decline in population and rarity were identified based on field observations as well as laboratorybased seed viability and germination tests. Based on these studies, 20 species were classified under critically endangered category, 21 under endangered, 11 under vulnerable, five under near threatened, and one species each under data deficient and least concern category. Threat assessment for 41 species was done based on number of locations and geographical range of occurrence, while for 18 species it was done based on restricted population and number of mature individuals. Over-exploitation and habitat degradation or loss were the dominant exogenous factors leading to decline in natural populations of the selected species. The major endogenous factors that lead to population decline and species rarity were low seed viability and germination, long dormancy period, less seedling recruitment, low population size, habitat specificity and narrow niche leading to restricted distribution.Keywords
