RESEARCH AND FIELD EXPERIENCE

a.    Floristic Study and Ethnobotany (1992-1994) Floristic survey was done in the Narayanapatna region of Koraput district of Orissa. During the work different ethnobotanicalinformations were collected from the Kutiakandh tribe of Orissa.  The area belongs to one of the most backward tribal regions of Orissa and is presently the most naxalite inflicted region in Orissa.

b.   Floristic Survey and Ecological studies in Eastern Ghats of Orissa (1994-1996):Extensive floristic survey was made in various parts of the eastern ghats of Orissa. Besides documenting the flora of the region, biomass and energy content in different plant species was also calculated in the laboratory. The energy expenditure, total material flow, biomass and energy flow patterns in forest based village ecosystems was studied with their different ecological implications. Developed two models on forest based village ecosystem sustainability and natural resource management.

c.    Floristic Survey, Ethno-botany and Taxonomic Study in Sikkim (1996 – 2002): Floristic andTaxonomic study in  particular reference to Sikkim Himalaya was undertaken.  Detailed of ‘The Flora of Kabi Sacred Grove and The Flora of Kyangnosla Alpine Sanctuary’ has been worked out. Contributed the detail description of three familiesGrossularicaceae, Polygonaceae, andCommelinaceaeto the state flora of Sikkim. Undertaken Seven exploration tours in North Sikkim [ Lachen, (2700m),  Thangu (4200m), Gurudangmar  (5500m), Lachung ( 2800m) Katao (4600m); Five exploration tours in Kabi Sacred grove  (1900m); Six exploration tours in Kyangnosla  Alpine Sanctuary ( from 3100m to 4500m) of east Sikkim, Two exploration tours in Tendong Reserve Forest (1700-2700m) and collected more than  6000 plant specimens including several interesting plant records for Sikkim and India. Documented the detailed flora of the Kabi Sacred Grove of North Sikkim andKyangnosla Alpine Sanctuary of east Sikkim. Contributed the complete description and collection of all species of familiesGrossulariaceae, Polygonaceae, andCommelinaceaeof Sikkim. The detailed taxonomic account of the family Polygonaceae of Sikkim worked out with two new combinations {Aconogonon rude (Meissn.) S.S.Dash&P.Singh&Persicariabirmanica (Gage) S.S.Dash&P.Singh}.

d.   Floristic Survey, ex-situ conservation, Botanic garden Education in BGIR (2002-2008): Floristic research in particular reference to the flora of the NCT region, development of woodlands and arboreatum, ex-situ conservation of rare and indigenous tree species and outreach education programmes of BGIR, carried out during this period. Also carried  out a project Digital Flora of National Capital Territory Region. During this period, under taken about nine exploration tours in the National Capital Territory Region including the ridge forest of Dehli, Barkhallake of the Haryana, Hindon basin of Ghaziabad district and collected more than 3500 plants specimens. Developed the herbarium and a thematic medicinal plant garden in BGIR.  Conducted four education programmes of BGIR, assisted in implementation of conservation programmes of BGIR.Developed  twenty-five  replicas of the different forest ecosystems of India for woodland &arboretum development with indigenous tree species. Undertaken eight plant collection tours to different parts of country, including Andaman Islands, Dang forest of Gujarat, Amarkantak& Jabalpur regions Madhya Pradesh, Kalinga hills of Eastern Ghats etc., and collected more than 10,000 plant seedlings of about 170 species. Presented one paper “An Approach to the integrated education programme in Botanic Garden of Indian Republic, India” in International Botanic Garden Education Symposium at Oxford University, Oxford, UK in 2006. Also attended the training workshop of the Darwin Initiative OSSSU Project held at Chengdu, PR China during 15-19 Oct. 2007.

e.    Floristic Survey, Taxonomic study in Arunachal Pradesh (2008-2011): Floristic account of Kurung kumey district of Arunachal Pradesh was worked out. This is one of the most inaccessible districts of Arunachal Pradesh with an altitudinal variation of 550 m to 5500 m. Many of the portions of the district were never survey earlier and survey first time during the project. Seven extensive floristic surveys covering tropical to alpine region (ranging from 550m to 4200m altitude) conducted in Kurung Kumey district of Arunachal Pradesh and collected about 4100 plant specimens. Documented the floristic composition early recovery plant community structure of shifting cultivated areas of Kurung Kumey district, which is of its first kind of study in the region.  The study resulted in documenting 1391 species including more than 75 species new to Arunachal Pradesh and 9 species new to India. Exploration of Vadse hills of Kurung Kumey district revealed 267 alpine species. Most of the species are having interesting affinities with adjacent   phytogeographical regions. The Vadse hill of Arunachal Pradesh has never been visited by any botanist.
