During the whole survey it has been found that among the groups of Rhesus macaque in Basistha Temple the mortality cases are very frequent. As our survey reports presenting the macaques are mostly injured due to Accident that is 63%. Accidents occur due to playing on the electricity poles, beaten by human, during playing and by Vehicles in the temple premise. The macaques are suffered from a lot of Viral, Bacterial & fungal infections. An around 32% percent case has been found where these macaques are suffered because of infections as reported. During the survey from September 2018 to April 2019 around 5% cases of Death has been found. The deaths occurred due to disease, accidents, vehicular accidents, electrocution and beaten up by human have been found.

Corridors in larger space of ecological conservation, occupy a niche. Their role and vitality in species conservation is well documented, but their definition is source of constant confusion. They have been generally understood to be linear landscape elements, meant to establish or facilitate connectivity across habitat and increase survivorship by increasing the diversity of specific gene pool. In more technical parlance, ecological literature defines corridors as a fundamental landscape element, being narrow strip of land which differ from the matrices on the either side. Kamrup (M) district is an administrative district of the Indian state of Assam. The area of Kamrup (M) is about 1528 sq. kms. Guwahati is the largest city in the indian state of Assam and also the largest urban area in the Northeast india. the latitude and longitude of the Guwahati are 26⁰14'45 o N and 91⁰73'62 o E. Deepor beel is a lake located to the south west of Guwahati city, in Kamrup district of Assam, India. To the south of Deepor beel there is Rani Garbhanga forest. there are five notified Elephant corridors across the forest to the Deepor beel. These five corridors are situated along the PWD Highway through Deepor beel 274 railway gate as the name of the corridor is given by the forest department. This corridor starts from the Rani forest in Meghalaya and Assam border and passes through the deep forest down to the Deepor Beel in search of water. The railway track cut the corridor in the tail end along with a VIP road that connect national highway-37 to the LGB airport Guwahati. The forest habitat contains many wild trees. The Elephant came down the corridor in search of water and food. Some of names of the plant they consume are Foxnut, Sal, Country Fig, Bamboo, Water hyacinth etc. The human population nearby the corridor in the beginning of the study was lesser in the month of August 2018 which increases over time and in the end of study period by the month of March 2019. The Elephant population is seen maximum in the month of August 2018 in number and minimum in the month of March'2019.

The habitat utilization pattern changes in blocks according to the availability of the fodder in the wet alluvial grassland. This study also shows that the habitat utilization pattern of rhinos is dependent upon food, grass cover and water. Keeping in mind rhino preference for wet alluvial grassland, it is essential for management authorities to maintain the hydrology of the sanctuary that supports wet alluvial grassland. Siltation due to flooding needs to be checked, de-siltation should also be carried out to maintain wetland dynamics in the park that in turn help in maintaining the wet alluvial grassland that rhinos prefer. There are potential opportunities to maintain preferred grassland habitat in the park with timely management interventions to ensure the long-term conservation future of rhinos. The results of this study resemble the study done by Hazarika (2007). The study reveals that the maximum use of grassland habitat by the Indian Rhino was 47.4%(n=148),28.2%(n=90) in wetland,20.8%(n=65)in woodland,3.5% in human resident area.

Assam is blessed with around 1,030 beels covering an area of 92,693 hectares (Goswami et. al). The potential of these beel fisheries could not be harnessed so far, as there is lack of proper management and change in the area of these beels due to encroachment. Presently, these beels are under the threat from many factors like pollution, habitat fragmentation and degradation which eventually lead to loss of biodiversity. The present investigation was undertaken, during the 2015–2016, to study the ecological parameters and hydrobiology of the Dhir beel for taking up proper managerial practices for sustainable utilisation of the available aquatic resources of the state. Dhir beel is situated at latitude 26⁰16′54.65″ North and longitude 90⁰23′21.52″ East with an altitude 34 m above sea level. It covers an area of about 689 hectare of land with depth of 7–22 feet during pick monsoon season. It is a floodplain lake of the Brahmaputra River basin is situated near Chapar town at about a distance of 5 km. The present investigation deals with the ichthyofaunal diversity of Dhir beel, its conspecific biotic communities present in the system and the understanding of its hydrobiology. A total of 65 species of fish under 37 genera belonging to 11 families and 6 orders have been identified. The fish productivity was around 14,740 kg during 2015–2016. The beel has shown an average temperature of 23⁰ C; transparency ranges from 49.2- 104 cm during the study period; the pH of water ranges from neutral to acidic i.e. 7.4 – 6.2; free CO2 fluctuated from 3.0 to 17.2 mg/L; alkalinity ranged from 25 – 38 mg/L; total hardness was quite low as found to be 24-36.5 mg/L. Thus, the present studies have revealed the ichthyofaunal diversity of the beel with reference to its hydrobiology and ecological parameters, and it is suggested that the productivity of the beel can be sustained the by managing the environmental degradations in and around the beel.

A well recognized Wetland situated at latitude 26 0 16'54.65'' North and longitude 90 0 23'21.52'' East and altitude 34 m ASL covers an area of about 689 hectare of land. It is a floodplain lake of the river Brahmaputra, situated near Chapar town, at a distance of 5 km. The present investigation deals with the diversity of the beel, the biotic communities present in the system with various management measures for optimizing its scenic beauty. The Dhir wetland has 17 family of birds and around 60 species of birds including 22 species of Aquatic which are often sighted in the beel an around. Also, the area nearby the Chakrashila wildlife sanctuary is enriched with Amphibian, Reptiles and Primates such as various Snakes, Crocodiles, Lizards, Short Nosed Fruit Bat, Rhesus macaque, Chinese Pangolin, Asiatic Jackal. Sighting of these animals are quite often around the wetland especially the Golden Langur, which might be a attractive tourist spot, with the provisioning of conserving the wildlife. The Water and Air Temperature (Maximum) shows a degree of congenial ecology of the beel throughout the four season. Thus, for the betterment and ecotourism developed in a sustainable manner could well be developed. The locals and NGO or Private organization should be asked to be the stakeholders for both the sustainable ecotourism as well as livelihood generation.
