is traditionally a very important district in relation to agriculture, education and culture Wetlands herein are of both natural and manmade origin Birbhum district formed by three subdivisions and nineteen blocks Almost all parts (at block level) of Birbhum District were surveyed from 2013 to 2014 Figure-1: Birbhum district (administrative) at a glance Code used W1 -Pansiuri Bandh , W2 -

Appraisal of Designated Usages / Effective Wetland Management Strategies (EWMs): A suitable management plan could be devised properly only if characterization of the type and source of pollutants entering the ecosystem is known Investigation of the physico-chemical and biological parameters in this regard helps in assessing the status, which is required for evolving appropriate restoration methods towards conservation and management In order to document different Designated Usages/ Effective Wetland Management, Strategies (EWMs), sample wetlands (1 from each block) were chosen in Birbhum 1889 JECET; Sep.2014- Nov 2014; Sec A, Vol.3.No.4, 1887-1894 Preliminary Santanu and Debnath district for monitoring (2013 to 2014), depending on the location, size and use pattern.In this context, a detailed survey study was carried out using NLCP guidelines 30 to derive the Designated Usages/Effective Wetland Management Strategies (EWMs) required for studied wetlands RESULTS AND DISCUSSION Designated Usages / EWMs for wetlands in Birbhum district: Figure-2 enumerates different EWMs for wetlands in Birbhum district Our study was focused to make a conception over what people (dependent directly/indirectly to wetlands) need for their water logged wealth So we enlisted some preferable management practices according to easiness of implementation along with of public interest i.e public demand Diversion and treatment of sewage, weed removal, reduced usage of water for agricultural practices are important measures in general A majority of wetlands harboring in urban area required Prohibition on Construction in wetland premises and Prohibition on wetland filling on priority basis which was also supported by earlier findings 31-32 Figure-2: A schematic diagram on the major Designated Usages/Effective Management approaches for wise use of wetlands in Birbhum district [Source: Ecological studies and structured questionary survey on 20 wetlands (blockwise) during 2013 to 2014 Here the names inside the circle indicate the suitable EWMs (Effective Management Strategies) with direct strong demand on wetlands Other outside the circle indicates those having variable degree of demands] 1890 JECET; Sep.2014- Nov 2014; Sec A, Vol.3.No.4, 1887-1894 Preliminary Santanu and Debnath Majority of Wetlands in the vicinity of rural villages need Bank protection, Desiltation/Dredging and improvement of water quality In some specific wetlands there is a malpractice of adding uncontrolled poultry manure to wetland water which causes further problems to aquatic life During winter months, there are some instances where wetland premises become horrible due to frequent picnic activities and where destruction of natural habitat was common leading to loss of biodiversity Removal of plastic waste and other solid waste along with improvement in picnic revenue system will be key developmental measures for these wetlands Similar observations were also documented by Aber et al.33 , Cools et al.34 and MoEF35, 36 in previous works Very few wetlands attributed with ownership dispute which may be minimized by consulting with local self-governments and administrative units According to our results, there is a massive need to construct bathing ghats (concrete structure for bathing) in the wetland premises This may be due to improper allocation/use of Governmental grants which is of serious concern As a drought prone district, people of villages depend on these wetlands for their day to day activity Bathing ghats are created poorly by authorities in the wetland which needs governmental attention Rural livelihood greatly depend on culture of fish fauna, and as a food source it has immense importance Results revealed that "effective and planned" societies need to formulate in different wetlands Some fish harvesting families who have strong will towards effective fish culture lack proper funding Government aided support will be a push for them along with creation of marketing chain We noticed that there are instances where under a several Governmental schemes by which huge amount of money (in lakhs) has been mobilized to create roads, infrastructure or other similar projects (which are beneficial to society) but if a small fraction of the money was allowed to incorporate to promote fisheries, agricultural practices or for promotion of duckery, village based small industries like brick, handloom, traditional knowledge based medical hub etc encompassing these wetlands; the scenario might be changed enhancing the socioeconomic profile as noticed in earlier works by Palit and Mukherjee 37 ; Gupta et al.38 , Downward et al.39 , van Dam et al.40 Among the other EWMs Promotion of tourism activities, Poultry farming, Floriculture are the leading ones according to popularity Our significant findings include formation of wetland protection groups (WPGs) and mass awareness programmes (MAPs) for local stake holders over wetland bioresources which may lead to wise use of wetlands in this part of country ACKNOWLEDGEMENT The study was supported by the Department of Science and Technology, Ministry of Science and

availability of food and shelter and presence or absence of predators However, wetlands in India, are facing tremendous anthropogenic pressures (Prasad et al 2002), which can adversely influence the structure of bird communities (Kler 2002; Verma et al 2004; Therefore detail study on wetland avifauna is important to protect them However, few studies have been carried out on the status and diversity of wetland birds in this eco region (Mukherjee and Gupta 2012) Fishes are one of the important elements in the economy of many nations as they have been a stable item in the diet of many people Study on fish fauna in India has been well investigated through some good and novel studies pioneered by (Talwar and Jhingran 1991; Kar and Dey 2002; Kar et al 2004) According to IUCN (2004) the total number of known species world wise is about 1.5 million Many more are yet to be discovered For many taxonomic groups the species of temperate zones have been fully recorded But in tropical zones with highest biodiversity the biodiversity data is far from complete In this context, the present study on wetlands in Birbhum District for cataloguing extent of key wetland biota was carried out to support the philosophy of wise use for these wetlands in future MATERIALS AND METHODS 2.1 STUDY AREA Birbhum District (Fig 1) lying within 23032´30´´ and 24035´0´´ N latitude and 88001´40´´ and 87005´25´´E longitude covers an area of 454.00 sq km It is traditionally a very important district in relation to agriculture, education and culture Wetlands herein are of both natural and man-made origin Birbhum district is formed by three subdivisions and nineteen blocks Almost all parts (at block level) of Birbhum District were surveyed from 2010 to 2014 Biosurvilance of Wetlands in Eastern India (Birbhum, West Bengal) for Wise Use 2138 2.2 ASSESSMENT OF WETLAND BIOTA Observations on the aquatic macrophytes, wetland birds and pisci faunal occurrence at 20 wetlands distributed over 19 Blocks in Birbhum District were carried out through frequent field surveys at seasonal intervals which comprises pre-monsoon (April-May), monsoon (August-September) and post-monsoon (December-January) The annual assemblage (presence or absence) of macrophyte species were noted and plants were identified using standard literature by Cook’s (1996) The Birds were photographed by CANON Power Shot (SX 150 IS) and identified using “Pocket Guide to the Birds of the Indian Subcontinent” (Grimmett & Inskipp 2007) Fishes were identified up to the species level, with the help of standard keys (APHA 2005), books (Talwar and Jhingran 1991) and online databases (Fish Base, 2012) Site specific relative abundance (here after will be noted as three categories: a) Common1/Most abundan2: +++ (birds1/fish2 observed in >50-% of study sites); b) Uncommon/Less abundant: ++ (25-50%) and c) Less common/Rare: + (3% Table 1(b): List of wetland birds species documented from wetlands of Birbhum district Family Scientific names of wetland birds species Alcedinidae Alcedo atthisa, Halcyon smyrnensisa Anatidae Anas creccab, Anas streperab, Aythya ferniac, Dendrocygna bicolora, Dendrocygna javanicaa, Nettapus coromandelianusb Ardeidae Ardea purpureaa , Ardeola grayiia, Bubulcus ibisa , Egretta garzettaa Charadriidae Charadrius dubiusb, Charadrius alexandrinusb Ciconiidae Anastomus oscitansa Jacanidae Hydrophasianus chirurgusc, Metopidius indicusa Motacillidae Motacilla albaa, Motacilla flavaa , Motacilla citreolaa Phalacrocoracidae Phalacrocorax nigera Rallidae Amaurornis phoenicurusb, Gallinula chloropusa, Porphyrio porphyriob , Fulica atrab 2143 Santanu Gupta and Debnath Palit Code used for site specific relative abundance (SSRA) of wetland bird species: a= Most abundant: +++ (>50-%);
