Monitoring of reintroduced Gaur (Bos gaurus gaurus) in Bandhavgarh Tiger Reserve, Madhya Pradesh Phase II Final report

Abstract

Bandhavgarh Tiger Reserve (BTR), located between the Vindhyas and the Eastern -- flanks of Satpura hill ranges in the Central India, supported a small population of gaur «40 individuals) till 1995. This population went locally extinct in 1998. Disruption of the migratory corridor between the forest of Bandhavgarh and Ghunghuti and Amarkantak was one of the factors attributed for the local extinction of gaur from Bandhavgarh. Even after the extinction of the gaur from the area, Bandhavgarh provided an excellent habitat for gaur. A proposal for reintroducing Gaur in BTR was initiated by the Madhya Pradesh Forest Department with support of the Wildlife Institute of India (WII) and & Beyond (previously known CC Africa). Gaur were reintroduced in Bandhavgarh form Kanha Tiger Reserve (KTR) in two phases with first batch of 19 individuals during January 2011 and second batch of 31 individuals during March 2012. Of the total of 50 individuals, 27 individuals were fitted with radio collars and monitored continuously. Monitoring of the reintroduced population was facilitated by the WII through a collaborative project titled "Monitoring of Reintroduced Gaur in Bandhavgarh - Phase I (2011-15)" The objectives of Phase I included studying the ranging pattern, habitat use and feeding habits of reintroduced gaur in Bandhavgarh Tiger Reserve and provided newer insight into lesser known aspects of gaur biology, behavior and ecology. The present study (Phase II) was carried out from April 2015 to March 2018, covering all the seasons in a year. The objective of the Phase II were to study the ranging pattern, habitat use, feeding habits, health considerations and competition of reintroduced gaur with other ungulates (Chital, Sambar and Nilgai) and camp elephants. A total of four different gaur herds were identified based on the presence of radio collared individuals and physically identifiable attributes of select individuals to study the ranging pattern of reintroduced gaur. During the study period a total of 1277locations were recorded from identified herds (n=4). During October and November 2017 six individuals (two males and four females) were fitted with collar (TELONICS VHF transmitters) and intensively monitored. The obtained radio-locations were plotted in ArcGIS 10.1. Minimum Convex Polygon (100% MCP) and Fixed Kernel Density (50% & 95% KFD) method were used to calculate home range of different gaur herds along different seasons (summer, monsoon and winter).
