Item Population Status and Haitat Use to Nilgai ( Boslaphus Tragocamelus) in Suklaphanta Wildlife Reserve(Department of Environmental Science, 2012) Bisht, KalpanaA study on the population status and habitat use of Nilgai (Boselaphus tragocamelus) in Suklaphanta Wildlife Reserve (SWR) was carried out during the summer (May–July) 2011. The study aimed at studying the current status, distribution and habitat use of blue bull in SWR. Population status and habitat utilization were studied by direct observation and vegetation composition in the study area was studied by quadrate method. For vegetation study, all the plant species inside the quadrate were counted as well as ocular estimation was made to measure the coverage for shrub and ground vegetation and approximate crown coverage was conducted for tree species. All the stage of tree including tree, pole size, sapling and seedling were also analyzed. A total of 17 individual animals with average group size of 1.89 were recorded during the study. The population shows the reflecting decline as well as in critical state from the previous recorded data probably due to poaching, high predation and poor habitat quality. Nilgai were found using three main different habitats available in the study area, Sal forest, Riverine forest and Mixed forest. Of these, Sal forest with grass patches was highly preferred mainly due to the availability of preferred browse and grass species and also the semi-open land helps animals to avoid the risk of predation. Riverine forest is also utilized due to the presence of different ground vegetation and the other browse species with their fruits in dry hot season. Apart from this Riverine forests provides shade and cover. Four major types of vegetation were found in the main study area. Sal forest was dominated by Shorea robusta, Cleistocalyxn operculatus. Riverine forest was mainly dominated by Murraya koenigii, Syzygium cumini, Trewia nudiflora, Mallotus philippensis and Mixed forest was dominated by Symplocos pyrifolia, Termenalia alata, Lagerstroemia parviflora, Ber (local name) tree species. Highest tree density was recorded in the Riverine forest (300 ind/ha) than in Mixed forest (225 ind/ha) and Sal forest (103.97 ind/ha).

Crop depredation is a major form of human–wildlife conflict that affects livelihoods of farmers living close to forest areas. The present study was carried with objective to find population status, habitat preferences and crop depredation by Nilgai in Lumbini Development Area (LDA), Rupandehi district from July to August 2017 based on line transect, indirect evidence collection and questionnaire survey methods. Total 59 Nilgai were observed from 9 transects with mean herd size 2.18 and density 7.512 individuals/ km 2 . Adult Female to Adult male ratio was 9.33. Distribution pattern of Nilgai was uniform type among studied samples. Maximum (n=4) Fecal matters and Nilgai (n=28) were recorded in human encroachment area but least Fecal matter (n=2) and Nilgai (n=5) were found in riverine and water logged area. Fifty seven percentage of the respondent stated that the damage is increasing every year. They have stopped planting Potatoes, Rahar, Pea and Grams. Crop depredation was found high in Madhuwani and Tenuhawa. Only 39.48% of the respondents used the protective measures, which is also not effective. Most of the respondents use Bamboo fencing as protective measures. Whereas guarding overnight, producing sound, scare crow, chasing Nilgai, tape film rounding, cattle dung spray and rotten fish spray were the traditional method applied to protect crop depredation. Disease, competition among the Nilgai, forest fire, habitat destruction, poisoning and killing of Nilgai were threats stated by the respondents.
