Here is an image of a stray dog chasing a herd of Blackbuck in the Jayamangali Blackbuck Conservation Reserve (formerly Maidenahalli). There were at-least 5 or 6 more dogs chasing the bucks, in a very organized fashion (not unlike dholes). This is a serious threat, as the fawns are easy targets for these dogs.
The reason these dogs enter the sanctuary is unchecked tourism. Often, tourists from nearby villages picnic inside the reserve and leave behind food, thus attracting dogs. When we brought up this issue with the RFO, he denied the fact that there could be stray dogs inside the reserve. When questioned about his last visit to the park, he said it had been a few months ago.
This image should support all those who oppose the ban against tourism in national parks. Without media and other photographers, a lot of issues would not come to the public notice.
