The paper presents a comprehensive account on taxonomic identity, niche characteristics and distribution pattern of two important bamboo species of Meghalaya viz., Phyllostachys mannii Gamble and Sinarundinaria griffithiana (Munro) C.S. Chao & Renvoize. The altitudinal distribution of both the species, and stand micro-environmental variables and soil characteristics indicate similar niche of the species. Both the species follow three-phase growth sequence. Based on the culm height, diameter and sheath morphology, it was concluded that Phyllostachys mannii, Phyllostachys assamica and Phyllostachys bambusoides are synonyms instead of being independent species as has been argued by many earlier workers. The distribution map of Phyllostachys mannii and Sinarundinaria griffithiana in Meghalaya shows extremely restricted distribution. Phyllostachys mannii has a restricted distribution world-wide and is confined to Meghalaya, Arunachal Pradesh and Nagaland of India, Yunnan province of China, and Myanmar. Sinarundinaria griffithiana has also extremely restricted distribution in Arunachal Pradesh, Assam, Meghalaya, Mizoram, Nagaland and hills of West Bengal in India, Bhutan, Laos, Myanmar, China and Vietnam. Hence, based on their global distribution pattern, both the species may be termed as Endemic to South-East Asia.Keywords

Indian Forester, Vol 135, No 4 (2009), Pagination: 459-470Abstract
The pattern of forest fragmentation was studied in Khangchendzonga Biosphere Reserve, Sikkim (KBR) and tree diversity was correlated with fragment size. A total of 23 forestfragments were identified in the KBR after intensive survey, of which ten fragments were in temperate forest, 12 in sub-alpine forest and one in sub-tropical forest. Maximum numbers of fragments were in 2-6 ha size classes. Landslide, wind storm and grazing by livestock herds were identified as the causes of forest fragmentation in KBR. The fragmentation of forest significantly impacted species composition, and community structure of trees in the forest, as evidenced from the differences in these attributes between the fragments and adjacent continuous forests.Keywords

Community Conserved Areas (CCAs) are a category of forests where communities have a stake or ownership and are increasingly getting recognized global recognition. CCAs across the globe are now being documented fortheir biological values, management regimes and conservation significance. Case studies were conducted in three states in North East India to document some of the CCAs in the region.Keywords

Conservation of Threatened Plants of India
Development of appropriate scientific principles and their application of these principles to develop technologies for the maintenance of biological diversity are two main goals of conservation biology. Although the origin of plant conservation is traced back to the beginning of agriculture when farmers started saving selected seeds for future use, conservation biology as a scientific discipline evolved only in the late 1970s. The realization that there is a need to save all the species to halt biodiversity loss has made conservation biology a frontline scientific discipline in the recent years.

In spite of its importance in nation-wide conservation planning, comprehensive information on geographic distribution of threatened plants in India is lacking. Even the threat status of these plants is ambiguous and the country’s effort to conserve them is not widely known. A critical analysis of these aspects is essential for identifying gaps in threatened plant conservation. Keeping these in view, we present a review of the existing knowledge on geographic distribution pattern of threatened plants of India, their threat status, and conservation action undertaken to recover these species. Using the available data, we unravel patterns of distribution of these threatened plants in different states of India. When ranking of the families was done based on the total number of species under different threat categories, Orchidaceae (644), Fabaceae (185), Poaceae (164), Rubiaceae (103), Asteraceae (88), Euphorbiaceae (72), Asclepiadaceae (62) and Acanthaceae (60) constituted more than half of the total threatened plant species of India. A review on conservation efforts so far undertaken in different parts of the country revealed that the biodiversity-rich phytogeographic regions such as the Himalayas, North East India, and Andaman and Nicobar Islands had lesser conservation efforts in comparison to the Western Ghats, Vindhyas and Peninsular regions of India. The skewed distribution of threatened plants in different states did not truly reflect their absolute presence or absence; rather it is the result of incomplete survey because of the difficult geomorphological and associated geo-climatic conditions, tough terrain and remote locations. In addition, the current data on threatened plants suffer from methodological shortcomings such as classification without using the population data that are so crucial in modern day threat classification, and lack of long-term observational data. The review emphasizes the use of modern tools such as ecological niche modelling for population inventory, area of occupancy and extent of occurrence, and trends in population size and regeneration for precise threat classification conforming to globally accepted methods (e.g. IUCN version 3.1). The works undertaken through the support of Department of Biotechnology, GoI for conservation of 156 threatened plant species under different disciplines of conservation biology during the past three decades have also been compiled and reviewed. A successfully tested protocol following an integrated approach for threatened species conservation is recommended for future conservation action.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

Categorization of species under different threat classes is a pre-requisite for planning, management and monitoring of any species conservation programme. However, data availability, particularly at the population level, has been a major bottleneck in the correct categorization of threatened species. Till date, threat assessments have been mostly based on expert opinion and/or herbarium records. The availability of primary data on distribution of species and their p opulation attributes is limited in India because of inadequate field survey, which has been ascribed to resource constraints and inaccessibility. In this study, we demonstrate that ecological niche modelling (ENM) can be an economical and effective tool to guide surveys overcoming the above two constraints leading to the discovery of new populations of threatened species. Such data lead to improved threat assessment and more accurate categorization. We selected 14 threatened plants comprising 5 trees (Acer hookeri Miq., Bhesa robusta (Roxb.) Ding Hou, Gynocardia odorata Roxb., Ilex venulosa Hook. f. and Lagerstroemia minuticarpa Debb. ex P.C. Kanjilal), 8 herbs (Angelica glauca Edgew., Aquilegia nivalis Falc. ex Jackson, Artemisia amygdalina DC., Begonia satrapis C.B. Clarke, Corydalis cashmeriana Royle, Dactylorhiza hatagirea (D. Don) Soo, Podophyllum hexandrum Royle, and Rheum australe D. Don), and 1 pteridophyte (Angiopteris evecta (Forst.) Hoffm.) having distribution range in North East India, Eastern and Western Himalaya, and Jammu and Kashmir. The study was carried out between 2012 and 2016. ENM-based survey led to the discovery and characterization of 348 new populations. The data so obtained helped in assigning conservation status to 10 species, which earlier were never classified due to data deficiency. Using the new population and distribution data of the remaining four species, only one was confirmed regarding its existing status and two species were classified as ‘Critically endangered’ instead of the present classification as ‘Endangered’. The fourth species was classified as ‘Critically endangered’ against the earlier category of ‘Least concerned’.Keywords

Use of metapopulation modelling in conservation of threatened plants has been demonstrated in this article taking Paris polyphylla Smith as an example. The metapopulation data collected from Sikkim Himalaya over a period of four years were analysed using RAMAS Metapop 5.0 software. Demographic projection, assessment of extinction probability, population viability analysis, and analysis of impact of disturbance on the metapopulation were undertaken. The metapopulation had 11 populations of which seven were in continuous forest (CF) and four were in forest fragments (FF). All the analyses were done in two model scenarios, viz. base-model (M1) representing the disturbed condition, and alternate model (M2) representing the undisturbed condition for three distinct layers of P. polyphylla populations, i.e. CF, FF in isolation, and collectively as metapopulation. The outputs of the deterministic population models in respect of CF and FF populations revealed that both the populations had contribution of growth and survival of plants to such decline was greater than the fecundity in both the models. Stochastic simulations revealed an extinction risk of >10% in 100 years in M1 scenario, which put the species under vulnerable category. The extinction risk of metapopulation significantly varied between the two models (M1 = 0.85; M2 = 0.42), conforming the hypothesis that disturbance and forest fragmentation have detrimental effect on the persistence of P. polyphylla. Recovery of species was most promising when reproductive individuals were introduced to the M2 model. Thus, both introduction of individuals in the field and protection of the populations with emphasis on the reproductive subset would result in achieving minimum viable population size or low threat status 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.

Populations of threatened plants are declining rapidly in natural habitats due to various anthropogenic activities. Reinforcement of the dwindling populations through reintroduction is a promising aspect for conservation of threatened plants. However, due to lack of standardized propagation methods of such plants, mass production of planting materials has become a challenge, thereby constraining the replenishment process. Identification of factors constraining the seed germination of threatened plants and addressing it effectively, are among the most cost-effective strategies for large-scale multiplication and subsequent conservation of the threatened species. Similarly, conventional low-cost vegetative propagation techniques such as grafting, air layering, and regenerating plantlets from ischolar_main-suckers, apical meristems, and stem cuttings often prove more successful for multiplication than relatively costly micropropagation techniques. In this article, we present a few case studies on low-cost mass propagation techniques of threatened plant species of India through seed, stem/apical shoot cutting and airlayering, that helped in the restoration of the species.Keywords

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
