“…They are found in a wide range of habitats and in a variety of soil types. Studies on rattans from India in general, and the Western Ghats biodiversity hotspot in particular, have been largely focused on taxonomy ( Renuka, 1992 , Lakshmana, 1995 , Sreekumar et al., 2006 , Senthilkumar et al., 2015 ) and population genetics ( Ramesha et al., 2007 , Lyngdoh et al., 2005 , Ravikanth et al., 2010 ).…”

Rattans, or canes, are one of the most important non-timber forest products supporting the livelihood of many forest-dwelling communities in South and North-eastern India. Due to increased demand for rattan products, rattans have been extracted indiscriminately from the Western Ghats, a 1600-km mountain chain running parallel to the west coast of India. Extensive harvesting, loss of habitat and poor regeneration has resulted in dwindling rattan populations, necessitating an urgent attempt to conserve existing rattan resources. In this study, using niche-modelling tools, an attempt has been made to identify areas of high species richness of rattans in the Western Ghats, one of the mega-diversity regions of the world. We have also developed conservation values for 21 economically important and endemic rattans of the Western Ghats. We identified at least two to three sites of extremely high species richness outside the existing protected area network that should be prioritized for in situ conservation. This study emphasizes the need to develop strategies for the long-term conservation of rattans in the Western Ghats, India.

“…In India, three geographical regions have specific rattan flora with minimum overlapping distribution pattern (Renuka 2002). However, unlike the attention received by rattans of the Western Ghats in peninsular India, only limited efforts were made in addressing the conservation of rattans of North East India (Lyngdoh et al 2005). Since rattans are distributed in small pockets and knowledge base for their genetic structure and diversity is only poorly developed, in situ conservation sites for conservation are yet to be established (Rawat & Ginwal 2009).…”

Rattan palms are one of the important nontimber forest produce which forms an integral part of the tribal population and contribute significantly in the rural economy. The demand of the rattan resources is substantial but most of the raw material is being collected from natural stands; and therefore, there is tremendous pressure on natural populations. Calamus guruba is one of the important rattan species of India and extensively harvested for a wide range of end products. In the present study, three populations of C. guruba naturally growing in Mizoram were characterized for their genetic diversity and population structure using Inter-Simple Sequence Repeat (ISSR) markers. A total of 197 bands generated in PCR amplification of 67 individuals with 10 ISSR primers. Among all the primers UBC 808 displayed maximum 25, while UBC 807 and UBC 827 showed the lowest 13 numbers of bands. Relatively high genetic diversity (PPB = 98.98 %, h = 0.271, I = 0.341) was recorded for the species with a moderate level of genetic differentiation (PhiPT = 0.282). Analysis of molecular variance revealed that the genetic differentiation among the populations is the significant and large proportion of the genetic variation (72%) resides among the individuals within a population, whereas only 28 % were found among the populations. UPGMA tree, PCoA plot and STRUCTURE analysis revealed that two ancestral groups captured the entire genetic variability. The baseline study on C. guruba is of paramount importance in devising programs for conservation and improvement.

“…Geographic Information System (GIS) and remote sensing provides a unique opportunity to assess (Fig. 5) and monitor deforestation, degradation, and fragmentation (Lyngdoh et al, 2005;Tejaswi, 2007). GIS integrates hardware, software and data for capturing, managing, analyzing and displaying all forms of geographically referenced information (http://www.gis.com/content/what-gis) and can be utilized for deciphering location, condition, trends, patterns and modeling of forests.…”
