The study was conducted from November 1995 to October 1996 in aquatic and terrestrial habitats. The investigation was mainly based on the direct observations, distribution of questionnaires and interviewing the local people. Observation was made once in a month during the study period. Each observation was conducted for five consecutive days and continued from early morning to evening. The study area covered the whole Padma river starting from Godagari to Rajshahi sadar and its associated land areas. Observation was made by walking in the plain land and using a mechanized boat in water areas in the morning and afternoon. Six plots were selected, such as Char Alatuli, Sultangonj Ghat, Godagari, Premtoli, Rajshahi (near ‘T-badgth’) and Kazla. Transect lines were used for counting the animals in the field. Transect lines were varied from 500 to 1000 m in length and 50 to 100 m in breadth. Sometimes, 100m × 100m sizes of blocks were also used when it was necessary for counting the population. During field observations, a pair of field binocular, still camera, spot light, plastic steel tape, preservatives, polythene bags, rubber band, map, etc were used. The species were identified following Banglapedia (2009). When any species was sighted more than 80% in field visits, it was recorded as very common (VC) species, common (C) when it was sighted 60-79%, fairly common (FC) when 20-59%, and few when species was sighted less than 20%. Besides, two or three times were seen in the whole study period is known as occasionally (O) found. The habitat type of each transect was recorded separately as (1) bush dwelling, (2) open place, (3) human habitation, (4) paddy field and (5) tree. Rajshahi is located in the north-west part of Bangladesh and very near to western border of India. Rajshahi district lies betwen 24.09° and 25.13° north latitude and between 88.02° and 89.21° east longitude. The study area included the Padma River and adjacent area from Rajshahi Sadar to Godagari Upazila. Geographically Rajshahi district is important, particularly because of the river Padma. The north, east and west sides of the study area are plain land mainly covered by crop, bushes, trees and village houses. But, the southern side of the Padma river is mainly sandy and open. Rajshahi including Godagari Upazila is a vast alluvial plain unrelieved by natural elevation of any kind. In the north, there are high sandy plains of large extent and along the west there is strip of high land composed of stiff red clay. The homestead forest is found in some parts having a variety of plants. The most of the land are covered by paddy field. The important plants are: khayer (Acacia catechu), babla (Acacia nilotica), bell (Aegle marmelos), shirish (Albizia spp.), chatim (Alstonia schalaris), kadam (Anthocephalus chinensis), bamboo (Bambusa spp.), tal (Borassus flabellifer), papaya (Carica papaya), neem (Azardirachta indica), jackfruit (Artocarpus heterophyllus), mango (Mangifera indica), coconut (Cocos nucifera), shisu (Dalbargia sisso), banana (Musa spp.), khejur (Phoenix sylvestris), kul (Zizyphus maritiana), Koroi (Derris robusta), Premkata (Chrysopagon aciculatus), durba (Cynodon dactylon), etc. During the rainy season some plants are grown like, kalmilata (Ipomoea aquatica), shapla (Nymphaea nouchalli), helencha (Enhydra fluctuans), padma (Nelumbo nucifera), kachuripana (Pistia spp.), paniphal (Tropa bispinosa), etc.
