Abstract

Status and distribution of Rhododendrons in a fragile ecosystem (temperate mixed forest and sub-alpine forest) of Mount Esii and surrounding hill ranges were studied. Not surprisingly, these hill ranges supported 8 taxa of Rhododendrons having varied status in the world (2 endemic and endangered, 2 endemic and rare, 1 rare and 3 common taxa). Within the study area, they showed contiguous pattern of distribution and their occurrence were most prominent within the altitudinal range 2,700-2,820m. amsl The local endemic species, Rhododendron macabeanum had highest density (11.9), most frequent in its occurrence (80 %) and also possessed greatest IVI (132.48) thereby acting as the dominant cover among the species of Rhododendron in these hill ranges. Majority of the remaining taxa (R. maddenii ssp. Crassum and R. elliottii; R. triflorum var. bauhiniiflorum and R. johnstoneanum) showed a high degree of competition for space and nutrients and consequently characterized by slow growth rate. These hill ranges proved to be an efficient habitat for Rhododendrons and will serve the purpose of in-situ conservation of Rhododendrons in general and endemic ones in particular. The endemic and endangered or rare species with low IVI (R. triflorum var. bauhiniiflorum, R. johnstoneanum and R. elliottii) should be given immediate attention for ex-situ conservation.

Abstract

North-East India is one of the richest in plant diversity in India and harbours many flowering plants throughout the seasons, which are excellent for making dried-flowers. Driedflowers making can be a potential small cottage industry for the region. This paper presents for the first time a list of plants suitable for dried-flowers making and the techniques of driedflowers making.

Abstract

Dzukou valley and surrounding hills situated between Manipur and Nagaland States are spread over an area of 27 sq. km. with a unique floristic wealth and biodiversity. The paper is an outcome of several exploration trips to the area. 335 species belonging to 223 genera and 114 families of sub-tropical evergreen, temperate and sub-alpine forest are enumerated. Of the taxa, two new generic record viz. Oriorchis Lindl. and Coeloglossum Hartm. For North East India and 24 species new record viz. Geranium tuberaria Jacquem, Malus sikkimensis (Wenzig) Balakr., Prunus rufa Hook.f., Astilbe rubra Hook.f. & Thomson.ex Hook.f., Rhododendron lepidotum Wall, ex G.Don, Rhododendron vaccinioides Hook.f., Primula deuteronana Craib, Primula stuartii Wall., Primula geraniifolia Hook.f., Euphorbia sikkimensis Boiss., Allium vietorialis L., Ligularia fischeri (Ledeb.) Turcz., Corybas himalaieus (King & Pantl.) Schltr., Oriorchis foliosa Lind., Parnasia wightiana Wall., Jasminum humile L. etc. for Nagaland and Manipur States. About 6% of the plants recorded were endemic to the area or endemic to eastern Himalaya.

Abstract

Dziiko Valley is situated on the border of Nagaland and Manipur States. Its flora is diverse and unique which gives and impression at first sight of the well know 'Valley of FloWers' in the Garhwal Himalaya. The nature's gift of blue and white Anemone yellow and white Primula, yellow Caltha and even the well known pink lily-the 'Sirol LilY (Lilium mackliniae Sealy) would one day all vanish if the present trend of biotic interference goes on. Hence, immediate conservation of the Dziiko Valley is necessary.

Abstract

The paper reports Lilium mackliniae, an endemic lily from north east India, its distribution and status in natural habitats. The main threats to the species and habitats due to frequent forest fire and rapid colonization by a dwarf bamboo after forest fire are discussed along with conservation measures which need to be taken for its protection.

Abstract

Studies on the seed viability of Nepenthes khasiana H00k.f. was conducted. Seeds were collected from different natural habitats and stored both at low temperature (5°C) and at ambient room temperature (25 ± 2 °C ) . Seed viability study was carried out by germinating seeds both in vivo and in vitro. For in vivo study seeds were sown on a leaf mold-based mixture in Petri dishes, whereasr in vito, the seeds were inoculated onto half-strength Murashige and Skoog (1962) medium. Within 2 week of culture over 50% of seeds germinated in vitro, whereas in vivo seed germination reached 50% after 8 week. Light and dark conditions were also used to test their effect on gemination. Addition of Gibberelic acid did not show any effect on the gemination of seeds. The study has shown high seed viability as shown from the high rate of gemination, both in vivo and in vitro. For optimum seed germination, high humidity (80 - 90%) and a warm temperature of around 25°C-30°C are essential. The study has also shown that seeds stored at ambient room temperature condition lose its viability rapidly within a year but seeds stored at low temperature (5°C) remain viable for over 5 years.

Abstract

During Plant exploration tour to Apatani Plateau, Lower Subansiri district in Arunachal Pradesh in October 2008, an aromatic bamboo was collected by the first author. The plant sample was collected from the hills of 'Luro Poliyang' near Ziro town, the head quarter of Lower Subansiri district. A clump of yellowish green bamboo with long internodes, was spotted, growing inside the subtropical forest at an altitude of c. 1715m. On approaching the bamboo clump, the local guide told that the bamboo's internodes contain clear water which is aromatic and nice for drinking. On cutting one of the bamboo culms, to the suprise it was found as told by the local guide. A single internode contains about 25-50 ml of the sweet aromatic liquid. It was also observed that the freshly cut and split bamboo when kept in a room gives a strong swet aroma for about a week. The plants appear to be rare as there were only a few clumps found in the whole hill during the survey. On close examination along with studies confirmed thatthe plant was reported as endemic to China (Dezhu & Stapleton 2006; Hsueh & Yi 1979). This is the first report from India and hence it is a new distributional record.

Abstract

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.

Abstract

To prevent extinction of threatened species, in vitro regeneration protocols for the propagation of six threatened species were standardized. The regenerated micro-shoots were ischolar_mained in nutrient medium supplemented with low concentrations of auxin. The well-developed plantlets were successfully established in field conditions, thus improving the probability of self-sustenance of the introduced populations. The success story of these six threatened species reaffirms the role of in vitro propagation in conserving plants facing the threat of extinction.

Abstract

Amentotaxus assamica D.K. Ferguson (common name: Chinese yew) belongs to the gymnospermic family Taxaceae. It is one of the two members of this family found in India, the other being Taxus wallichiana. Amentotaxus is a tall dioecious tree reaching a height of 20 m with horizontal or drooping branches. It is confined to small pockets in the Eastern Himalaya, specifically in Arunachal Pradesh, India. The tree finds usage for making pillars and posts in house construction. Following the ‘critically endangered’ status assigned to the species by the Conservation Assessment and Management Prioritization (CAMP) workshop (February 2003), attempts have been made to locate and assess its population status. Gajurel et al.¹ recorded 22 individuals along with five saplings and two seedlings from Mithumna, Dalai Valley, Arunachal Pradesh, the site from where the plant was first reported by F. Kingdom War in 1928. Das et al.² reported a fairly large population at Turoo forest, Sagalee subdivision, Pampum Pare district, Arunachal Pradesh, having tree density of 40 individuals/ha.
