Lianas are important in forest ecosystem and strongly influence the forest dynamics and diversity. Lianas are common in the tropical moist deciduous and rain forests, which are competing with other forest trees. Little information is known on the habitat specialization in tropical lianas diversity and the root causes for variation among forests in liana species composition. A total of 170 liana species (≥ 1.5 cm girth at breast height) representing 109 genera and 43 families were reported in 5×5 m quadrate samples along with their climbing modes in the tropical forests of northern Eastern Ghats of Andhra Pradesh, India. A total of 210 grids were sampled in study area and reported that Convolvulaceae was the dominant family with 23 species followed by Papilionaceae, 22 species and Asclepiadaceae, 19 species and Ipomoea was the largest genera. Woody lianas were dominated by 128 species and these are classified into six climbing modes consisting in stem climbers (53.5%) that were the most predominant followed by stragglersunarmed (14.7%), stragglers armed and tendril climbers (13.5% each), root climbers (2.9%) and hook climbers (1.8%). The most dominant liana species in the northern Eastern Ghats were Acacia sinuata and Bauhinia vahlii. The results of this investigation suggests that better management and protection is an important for in situ conservation of liana diversity and involving local people is emphasized.

The population of Croton scabiosus, an endemic tree species of southern Eastern Ghats of Andhra Pradesh, India was assessed through random sampling in 15 localities spread over 8 locations. In sampled 37.5 h area, a total of 8737 mature individuals of Croton scabiosus was recorded. Of the 8 locations, Sanipaya sub population was found stable and considered elite owing to the maximum number of mature individuals, girth and height. In spite of good adult population, low number of seedlings and saplings of the species across the native terrain indicates its poor germination and recruitment warranting both in situ and ex situ conservation measures.

We provide a check list of angiosperm climbing plant species, along with their climbing modes, enumerated from a total of one hundred and fifty grids in tropical forests of southern Eastern Ghats, peninsular India. The Eastern Ghats constitute an important biodiversity area in India and have been studied earlier mainly for the floristics, and that too confined to a few prioritized sites. Lianas, the woody vines contribute substantially to the diversity and structure of most tropical forests. Yet, little is known about the importance of habitat specialization in maintaining tropical liana diversity. A genera and 40 families are included in this enumeration.

Ecological Zones

We present a comprehensive approach to carry out community-wide assessments of in situ conservation of forest trees based on basic botanical and ecological data. This is a first step, resulting in a consistent framework to set priorities for collection and inclusion of species- specific biological and genetic information. We use botanical sample data to generate high-resolution distribution maps as a basis for a gap analysis of how well each species is represented in protected areas. To account for adaptive genetic variation of tree species we stratify populations by ecological zones that represent different macroclimates. In a detailed example for Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), we show that under certain conditions this approach can pinpoint gaps at the level of genetically differentiated populations without actually using genetic data. In a comprehensive case study, evaluating the outcome of a major protected area expansion between 1991 and 2001 for British Columbia, we demonstrate how extensive results from a community-wide GIS analysis can be summarized and presented for decision-making. We provide methods to identify and efficiently cope with in situ conservation gaps, where lack of data or low protected area coverage requires additional conservation efforts or collection of better data.

Loss Of Genetic Diversity

To counteract loss of genetic diversity crucial for current and future tree improvement, tree breeders have conserved forest genetic resources in situ in their natural ecosystems in protected areas or ex situ in plantations, seed orchards, and breeding arboreta. This article reviews the genetic consequences of these two conservation methods in terms of single-locus and multilocus population structure from electrophoretic studies of natural forests and breeding populations. Although natural forest populations have maintained high level of genetic diversity and exhibited low level of population differentiation, loss of genetic diversity would occur during the entire conservation process, from population establishment to management of breeding and production populations. Since forest trees are still at their earliest stage of domestication in Canada, loss of genetic diversity comes primarily from the initial sampling process during population establishment. We discuss the optimal sampling strategy during population establishment to conserve common and widespread alleles, common and localized alleles, rare and widespread alleles, and rare and localized alleles. We also discuss three methods for studying the multilocus structure of forest trees and show how such information would be useful for conserving co-adapted gene complexes. We conclude that being small and maintained in controlled environments, ex situ conserved populations would retain less genetic diversity than in situ conserved forest populations. While ex situ conservation is operationally convenient for the short-term gains in tree improvement, we believe in situ conservation is essential for renewing the genetic diversity to meet the changing environments of an uncertain future.

Effective Conservation

We provide a list of tree species enumerated from a total of 60 ha area sampled in the tropical forests of southern Eastern Ghats, Tamil Nadu, India. A total of 272 tree species (Ā 30 cm girth at breast height) representing 181 genera and 62 families were recorded. Euphorbiaceae with 25 species was the most speciose family, followed by Moraceae (17 species), Rubiaceae (17), Rutaceae (14) and Lauraceae (12). At the generic level, Ficus dominated with 12 species, followed by Diospyros (9), Acacia (6), Terminalia (6) and Grewia (5). Anthropogenic activities such as hill cultivation, construction of dams, roads, buildings, etc. affect the already fragmented southern Eastern Ghats, and underline the need for effective conservation measures.

Essential Contribution

Way Kambas National Park (WKNP) is home of five protected big mammals including sumatran elephants.  It shares its border with 22 of 37 villages surrounding the national park.  Understanding their existence in the wild is a priority, and  wildlife genetics is a crucially needed. Besides poaching and habitat fragmentation, wildlife-human conflict is one big issue.  Elephant Training Center (ETC) in WKNP is built for semi in-situ conservation effort on captive sumatran elephants that mainly have conflict histories with local people.  Participative observation and bio-molecular analysis were conducted to learn the importance of captive Sumatran elephant for conservation effort.  Through captive sumatran elephants, database and applicable methods are expected to be developed supporting the conservation of their population in the wild.  Participative observation and molecular identification was carried on captive sumatran elephants in ETC, WKNP under multiple year Terapan grant of Ministry of Research and Technology Higher Education, Indonesia. Gene sequence and cytological analyses showed that the captive sumatran elephants are closely related and tend to be domesticated.  Translocation among ETC to avoid inbreeding, and maintaining the captive sumatran elephant as natural as possible are highly recommended. Developing genetic database can be a reference for both captive and wild sumatran elephants.

Extended Range

Eastern Ghats are discontinuous hill ranges passing through Orissa, Andhra Pradesh and Tamil Nadu located between 11⁰30' & 22⁰N latitude and 76⁰50' & 86⁰30'E longitude. Bryophyte flora of this region is still very less explored. During a recent field exploration to Eastern Ghats region of Tamil Nadu three moss taxa viz. Solmsiella biseriata (Austin) Steere, Aulacopilum glaucam Wilson and Groutiella tomentosa (Hornsch) Wijk & Marg. have been identified as new additions to moss flora of Eastern Ghats. The present study provides the information regarding extended range of distribution of these taxa in India and a compensable account of morpho-taxonomical details with earlier described taxa from other bryogeographical zones.
