Abstract: The present paper is the outcome of an extensive floristic survey conducted in two phases by the authors in Kyongnosla Alpine Sanctuary, East Sikkim, India. During the study 411 taxa (400 species, 04 subspecies and 07 varieties) belonging to 173 genera and 54 families were recorded. The most dominating family was Asteraceae with 44 species followed by Ericaceae 28 species, Ranunculaceae 26 species, Polygonaceae 24 species and Rosaceae 20 species. These five families represent 34.13% of the total taxa recorded from the sanctuary. About 12 families were represented by only one species each. The most dominating genus was Rhododendron (18 species) followed by Primula (16 species), Pedicularis (15 species), Gentiana (11 species), and Impatiens (10 species). Among the different growth forms, herbs contributed the maximum (86.61 %) followed by shrubs (7.79%), trees (4.87%), climbers 0.49%, and epiphyte (0.24%).

 

Keywords: checklist, eastern Himalaya, floristic survey, growth form, Himalayan forest types.

 

 

 

Comprehensive documentation and identification of plant diversity is one of the targets of Global Strategy for Plant Conservation (GSPC). Being a signatory of the Convention on Plant Diversity (CBD), India is committed towards achieving a complete inventory of plant diversity of all the protected and nonprotected areas (Singh & Dash 2015). India is endowed with diverse ecosystems ranging from high altitude cold deserts to hot and humid coastlands which show rich floral diversity. Continuous survey and exploration in different habitats have facilitated an updated inventory of plants, which opens up different potential linkages among various sectors and implementation of appropriate action on management and sustainable conservation.

Kyongnosla Alpine Sanctuary (KAS) situated in the East district of Sikkim (Figure 1) between 27022’33”N  latitude and 88044’13”E longitude  covers an area of 31 km2 between the elevation ranging from 3,000–4,500 m.  In the initial notification 45/WL/83/625 dated 29.viii.84, the area demarcated was 4.5 km2, however in the second and final notification 45/WL/F/92/1585/F&WL dated 12.v.92 the area of the sanctuary  extended to 31 km2. The vegetation of the KAS comprises different ecological zones depending upon the elevation, viz., mixed Rhododendron temperate forest, coniferous forest along open slopes and ridges and alpine scrubs on upper reaches. Though it encompasses a small area, the sanctuary supports a luxuriant temperate and alpine vegetation owing to its unique topography, variation of altitudes and high annual precipitation. All  representative Himalayan forest types (Champion & Seth 1968; Dash & Singh 2010), such as northern montane wet temperate forests (dominated by Oaks Quercus, and Acer); Himalayan moist temperate forests (dominated by Rhododendron spp., Tsuga dumosa, Picea spinulosa, and Abies densa); Himalayan dry temperate forests (represented by gregarious growth of Juniperus wallichiana); sub-alpine forests (represented by  Rhododendron  spp., Betula utilis, Sorbus spp.) and alpine forests (gregarious patches of  Rhododendron thickets, Juniperus recurva, and dense herbaceous growth) exist. The subalpine and alpine forests are present with climax formations, self-generating, resilience forest types.  Nevertheless, this diversity is variously challenged by several driving forces such as over exploitation of medicinal plants, heavy grazing by yaks and developmental activities in the fringe areas. Extensive surveys of the study area were conducted to document the floristic composition in different altitudinal gradients of the KAS from July 2017–March 2020, being a part of our project work ‘Biodiversity Assessment through Long-term Monitoring of Plots In the Indian Himalayan Landscape’ under the National Mission of Himalayan Studies. In the paper we have enumerated 411 flowering plants occurring in the sanctuary with their correct accepted names.

 

Materials and Methods

The entire area of KAS was surveyed extensively in two phases. The first phase during 1998–2000 by the first author (SSD) and the second phase during 2017–2020 by the first two authors (SSD & SL). More than 1,300 plant specimens were collected and processed following standard protocols (Jain & Rao 1977). All the collected specimens were identified consulting available literature (Hooker 1872–1897; Grierson & Long 1983; Long 1984; Grierson 1984; Grierson 1987; Grierson & Long 1987; Hajra & Verma 1996; Srivastava 1998; Aitken 1999; Aitken, Grierson & Long 1999; Grierson & Springate 2001; Lucksom 2007; Gogoi et al. 2018; Maity et al. 2018; Mao et al. 2018; Lahiri et al. 2019; Dash et al. 2020; Lahiri & Dash 2020) and voucher specimens were deposited at BSHC and CAL for future reference. Earlier collections made from KAS by different collectors and available in different herbaria (ASSAM, BSHC, and CAL) were also taken into consideration while preparing the present enumeration. In the present inventory, families are arranged as per APG IV system of classification (Chase et al. 2016) and within the family, genera, and species are arranged alphabetically. For determination of current names, the World Flora Online (http://www.worldfloraonline.org) and Plants of the World Online (http://www.plantsoftheworldonline.org) were consulted.  The enumeration comprises family names, correct scientific names followed by valid author citation, growth form, altitude ranges where they occur and collection details along with the field number and herbarium acronym in each of the columns. Range of distribution of a species has been determined taking into  consideration the present collections and also earlier collections deposited in different herbaria.

 

Results and Discussion

The enumeration of the flowering plants of KAS includes 411 species belonging to 173 genera and 54 families (Table 2). The family Asteraceae with 44 species is the most dominant family, followed by Ericaceae (28 species), Ranunculaceae (26 species), Polygonaceae (24 species), and Rosaceae (20 species). These families represent 34.13% of the total species recorded from the sanctuary. Among the genera, Rhododendron is the most dominant genus represented by 18 species, followed by Primula (16 species), Gentiana (11 species), Impatiens (10 species), Corydalis (9 species), Saxifraga and Rhodiola (7 species each). Three families, i.e., Acanthaceae, Carlemanniaceae, and Euphorbiaceae are represented by only one species.

The plants present in the sanctuary show wider distribution in other parts of the Himalaya too, such as Allium prattii, Cyananthus lobatus, Gaultheria trichophylla, Juniperus recurva, Nardostachys jatamansii, Rosa sericea, and Streptopus simplex, which have a wider distribution from North-West Himalayas to China. The taxa showing eastward extension are Cassiope selaginoides, Gentiana stylophora, Morina nepalensis, Panax pseudo-ginseng, Primula sikkimensis, and Ribes luridum.  Many species which are restricted only to eastern Himalaya are represented by Abies densa, Meconopsis villosa, Rhododendron lanatum, Impatiens cymbifera, Codonopsis benthamii, Codonopsis subsimplex, and Primula kingii.

The basal angiosperm is represented by only one species Schisandra grandiflora (Wall.) Hook.f. & Thomson, while eudicots are represented by 85.88% and monocots by 13.86% of total species in KAS (Table 1).

The sanctuary provides a suitable habitat both for temperate and alpine species and holds many endangered and endemic species, viz. Aconitum ferox, Bhutanthera albomarginata, Ponerorchis puberula, Aconitum novoluridum, Codonopsis benthamii, Codonopsis subsimplex etc. The present study also recorded some of little-known species viz. Bhutanthera albomarginata, Ponerorchis puberula, Aconitum novoluridum, Codonopsis benthamii, Rubus lasiostylus, Sinopodophyllum hexandrum, Gentiana leucomelaena, Veratrilla burkilliana, Tibetoseris depressa, and Pedicularis porrecta.  The sanctuary has been facing a continuous challenge in its community structure due to various anthropogenic interferences and heavy grazing which need to be controlled.
