Author(s): Sanjyoti Subba, Sanchi Subba, Sumitra Nepal
Abstract: A total of 75 species under 68 genera falling in 49 plant families, and 6 of ferns and fern-allies were recorded along 27 sampling plots were laid, covering an area of 0.27 ha during May 2014. We covered the temperate coniferous forest & sub-alpine forest and the elevation ranges between 2800m to 3200m asl. The topmost canopy covers species such as Tsuga dumosa, Picea smithiana, Daphniphyllum himalense and Rhododendron arboreum. Amongst them most dominant taxa are Tsuga dumosa and Rhododendron species was found growing up to 3000 m asl. The common shrub species such as Viburnum erubescens, Daphne cannabina, Rosa sericea, Salix sp., with herb species such as Arisaema griffithii, Fragaria nubicola and Paris polyphylla, were recorded. Apart from these, the area has rich diversity of bird species. Yakchey (Lachung Range) is one of the biodiversity hotspot in this region. The study area is located near Shingba Rhododendron Sanctuary, home to Rhododendron niveum, an endangered and endemic plant in this area. The area is disturbance by natural and anthropogenic pressure. So, it may cause great loss of biodiversity.
