I agree with Abhishek, getting the know the ground realities is very important before deciding on what to do and how. But it is critical to rope in the support of some local / nearest conservation based organisation which is into feild activities. If not support from even cultural/ social groups based in the area will come in handy. Local support is critical and will to a great extent help overcome language barriers and suspicion which somtimes results in flawed results to field surveys.
