Abstract :

The study was carried out to assess the faecal cortisol concentration in gaur entering the agricultural fields around the forest and in domestic bovines comprising of non descriptive cattle and cross bred cattle, in order to arrive at the baseline values pointing to stress factors. The adjoining areas of Bandipur wildlife region, Sathyamangalam wildlife region and Anamalai wildlife region of Tamil Nadu, India were included in this study programme. The documentation of the quantifiable meteorological factors in the identified conflict areas was done. The mean faecal cortisol concentration in the case of gaur that entered in the agricultural fields adjoining the Bandipur wildlife region, Sathyamangalam and Anamalai region were found using ELISA (Enzyme Linked Immuno Sorbent Assay). The mean faecal cortisol concentration of non descriptive cattle as well as cross bred cattle was also documented to be used as primary and secondary control values. The occurrences of conflict were also classified as low, medium and high based on the intensity. The climatic inclusions on the stress and conflict levels were studied. Suitable management related measures were recommended pertaining to the findings observed in this study like increased mean faecal cortisol concentration in gaur, comparative wild gaur- human conflicts pertaining to the variations in the meteorological factors of the areas were studied. The findings demonstrated that fecal glucocorticoid assays provide an index of physiological stress in gaur and may prove useful in addressing conservation and conflict issues
