Kunwar, Krishna K. Shrestha and Ram C. Poudel With the assistance of Sangeeta Rajbhandary, Jeevan Pandey, Nar B. Khatri Man K. Dhamala, Kamal Humagain, Rajendra Rai, Yub R. Poudel Ethnobotanical Society of Nepal (ESON) Karthmandu, Nepal In collaboration with Shree High Altitude Herb Growers Group (SHAHGG), Ilam Deep Jyoti Youth Club (DJYC), Panchthar September 2008 ii Preface The Eastern Himalaya stands out as being one of the globally important sites representing the important hotspots of the South Asia. The Eastern Himalaya has been included among the Earth’s biodiversity hotspots and it includes several Global 200 eco-regions, two endemic bird areas, and several centers for plant diversity. Kanchenjungha-Singhalila Complex (KSC) is one of the five prioritized landscape of the Eastern Himalaya, possesses globally significant population of landscape species. The complex stretches from Kanchenjungha Conservation Area (KCA) in Nepal, which is contiguous with Khanchendzonga Biosphere Reserve in Sikkim, India, to the forest patches in south and southwest of KCA in Ilam, Panchthar and Jhapa districts. The entire occidental and austral landscapes of Mt. Kanchenjungha is rich in floral diversity. There is an account of over 2900 plant species from KCA and over 600 plant species from Kanchenjungha-Singhalila Ridge (KSR) of Ilam and Panchthar districts. Inventory and conservation of vascular flora of pristine, rugged and bountiful landscapes of KSR was possible with financial support from Critical Ecosystem Partnership Fund (CEPF), USA. We express our deepest gratitude to CEPF for providing support. The support from local collaborators – Shree High Altitude Herb Growers Group (SHAHGG), Ilam and Deep Jyoti Youth Club (DJYC), Panchthar is in worth. Local people’s participation during participatory meetings and interactions and field level research works and implementations is acknowledged. Our special thanks goes to WWF Nepal team (Dr. Sarala Khaling, RC-SE Asia, CEPF and Mr. Ang Phuri Sherpa, NC-Nepal, CEPF) for their facilitation and technical guide.

It was carried out in four VDCs of Ilam and five VDCs of Panchthar districts of east Nepal in April 2007 – March 2008 with the implementation support from Shree High Altitude Herb Growers Group, Ilam and Deep Jyoti Youth Club, Panchthar. The objectives of the project were to inventory and document of plant diversity and their associated habitats, identify and assess the rare, threatened, endemic and archaic plant species and key habitats, and develop conservation strategies of the species and habitats through participatory and scientific approaches. Literatures/specimens review and plant collection expeditions were means for inventorying.
