“…An average richness 18 species ≥ 1cm diameter ha -1 in our study sites coincides with the other studies reported from Indian tropics: Western Ghats-17-23 species 1.08 ha -1 in two montane evergreen forests (Mohandass et al 2015), 19-22 species ha -1 in two tropical forests of northeastern India (Barik et al 2015). However, the average liana richness of this study is much lower than the results obtained from other parts of Asia: India (Muthuramkumar & Parthasarathy 2000, Padaki & Parthasarathy 2000, Muthumperumal & Parthasarathy 2010, South China (Ding & Zang 2009), Africa: Ethiopia (Senbeta et al 2005), Neotropics (Ibarra-Manriquez & Martinez-Ramos 2002, Burnham 2004), Panama (Putz 1984), Australia (Chalmers & Turner 1994) and New Caledonia (Bruy et al 2018). This could be attributed to variation in total forest area (TDEFs occurs as patches), forest type and dynamics, stature, macro and micro-climatic condition, and disturbances by various means (overexploitation of resources, illegal cutting of host plants and lianas and grazing by animals, etc.).…”

Lianas are important components of tropical forests that play a crucial role in forest dynamics. We investigated biodiversity and carbon stock of lianas in two tropical dry evergreen forest (TDEF) sites, the relatively undisturbed Sendhirakillai (SK) and disturbed Palvathunnan (PT) by establishing one-hectare plot in each site. All lianas ≥ 1cm diameter (measured 1.3 m from rooting point) and trees ≥ 10cm girth (measured at 1.3 m from ground) were enumerated to ascertain species richness and stem density of lianas and trees with respect to site disturbance. Liana diversity totaled 24 species (16 in SK and 20 in PT) in the two studied sites. Liana density totaled 1182 individuals (744 ha -¹ in SK and 438 ha -¹ in PT). Fifty percent of species were shared between the two sites. A considerable variation in the density, dominance and basal area of different species was found between the sites. No dominant family was common to both the sites. Stem twining and zoochory was predominant in both disturbed and undisturbed sites. Lianas comprised 36.4% (SK) & 48.8% (PT) of the total woody species richness (lianas + tress) and 37% (SK) and 38.3% (PT) of the total woody species density. The mean aboveground biomass and carbon stock of lianas were 7.2 Mg ha -1 and 4.5 Mg ha -1 , accounting for 1.94% of total woody species community (trees + lianas). The aboveground biomass and carbon stocks were highest in undisturbed site SK compared to disturbed site PT. The extent of liana diversity and their contribution to the total woody plant abundance and biomass highlight the importance of lianas in forest functioning, dynamics and mitigating climate change. Considering the biodiversity TDEFs hold and the current level of human disturbance, a holistic approach in conservation is emphasized.

“…Most species rich family was Convolvulaceae (9-species) followed by Asclepiadaceae (5-species) Lianas families of Asian forest are dominated by Apocynaceae, Fabaceae, Anonaceae, Combrataceae, Loganiaceae, Rutaceae etc. [9,13,20,21,24,44]. The dominance of liana families by Apocynaceae, and Fabaceae in wide-ranging tropical forests [1] is also evident in this study.…”

Background and Aims: The Mountains of the Western Ghats are the second most important shelter in the world for threatened species. The current paper is an attempt to study the conservation assessment of rare, endangered and threatened species (RET) of the southern Western Ghats. A species is endangered when it is threatened with extinction. Since time began, countless species have gone extinct from natural processes. The present study was conducted to identify the rare, endangered and threatened climbing plants in Southern Western Ghats of Tamil Nadu, India. Methods: The plant collection and identification of the RET listed climbing species of the Southern Western Ghats was done during 2011-2014. The collection and identified RET plant species from the study were selected from different hills (forest) of Tamil Nadu. During the work the selected study sites were visited, plant specimens were collected and systematically pressed, stored for identification. Key results: A total number of 285 climber species comprising 125 genera of 41 families were identified from Southern Western Ghats of Tamil Nadu. Out of 285, 33 species are listed as RET species like Ceropegia mannarana Umam. & Daniel and Gloriosa superba L. fond to be Endangered species and Celastrus paniculata Willd., Aganosma cymosa G.Don. Smilax wightii A. DC., Corallocarpus gracilipes Cong., are rare species. The most specious families include Asclepiadaceae (7 species), Convolvulaceae (5-species) followed by, Fabaceae (4-species), Cucurbitaceae and Liliaceae each 3-species, and all the other remaining families having two or one species each. Conclusion: Some of the threatened factors such as over-exploitation of natural resources and other anthropogenic activities adversely affect the existing ecosystem and it may lead to the rarity of many species in future. There is an urgent need for developing pragmatic conservation strategies for endemic plants in the southern Western Ghats, which may lead to their effective protection.

“…These generalizations are based on several site-specifi c studies followed by meta-analyses (Schnitzer 2005 ). Most of these studies are from tropical forests (DeWalt et al 2000 ;Muthuramkumar and Parthasarathy 2000 ;Chittibabu and Parthasarathy 2001 ;Nabe-Nielsen 2001 ;Parthasarathy et al 2004 ;Senbeta et al 2005 ;Addo-fordjour et al 2008 ;Cai et al 2009 ;Yuan et al 2009 ;Muthumperumal and Parthasarathy 2010 ;Schnitzer et al 2012 ;Anbarashan and Parthasarathy 2013 ;Naidu et al 2014 ) with very few from subtropical (Hegarty 1991 ;Rice et al 2004 ;Malizia and Grau 2006 ;Campanello et al 2007 ;Yuan et al 2009 ) and temperate forests (Londré and Schnitzer 2006 ;Allen et al 2007 ;Ichihashi et al 2009 ;Leicht-Young et al 2010 ;Chettri et al 2010 ). Such generalization therefore needs validation with more studies from subtropical and temperate forest ecosystems.…”

Lianas constitute an important component of plant diversity in a wide range of ecosystems. The liana diversity has been reported to have critical role in maintaining ecosystem structure and function, with a predicted greater role to play under changing climate conditions. However, our understanding on the diversity pattern of lianas in different forest ecosystems along an elevation gradient is limited. Studies on lianas in the Eastern Himalayas and North-eastern region of India are very few. In this paper, we review the status of liana research in the two biodiversity hotspots viz., the Himalayas and Indo-Myanmar, and conducted primary studies in selected high diversity forests of the region to understand the patterns of liana diversity along elevation gradient in the Himalayas. The diversity and distribution of lianas in three major forest types representing the dominant ecological zones of the region viz. tropical, montane-subtropical and temperate were studied using liana census protocol of Gerwing et al. (2006). We recorded 196 liana species in three forest types in the states of Arunachal Pradesh, Sikkim and Meghalaya in northeastern India through plot-based fi eld survey. The diversity and abundance of lianas were greater in sub-tropical and tropical forests than temperate forests. Threat assessment for liana conservation was suggested for their in situ conservation.
