AVIFAUNA: In the 1980s, there were about 60-70 bustards in and around Rollapadu and the Sanctuary was developing very well, but due to subsequent mismanagement of the grasslands, and poaching of bustards during their movement away from Rollapadu, the bustard population has come down drastically. Not more than 20-25 birds remain. Large flocks of 15-20 birds are rarely sighted now. Another globally threatened species that is now regularly seen is the Lesser Florican Sypheotides indica (Sankaran and Manakadan 1990, Manakadan and Rahmani 1999). About 150 bird species are reported in and around Rollapadu Wildlife Sanctuary, including the second largest roost of harriers (Circus spp.) in India (Rahmani and Manakadan 1986). Nearly 2,000 harriers of four species are found in the grasslands (Circus pygargus, C. macrourus, C. aeruginosus and C. melanoleucos). This site can easily qualify for A4ii criteria (known or thought to hold, on a regular basis, >1% of the global population of a congregatory seabird or terrestrial species).
OTHER KEY FAUNA: The most conspicuous mammal, which has benefited most from protection, is the Blackbuck Antilope cervicapra. In 1985, its population was not more than 17 individuals. Now, it has gone up to 500 (Forest Department records, and our observations). A pack of Grey Wolf Canis lupus inhabits the Rollapadu grasslands. Indian Fox Vulpes bengalensis is also found, and shows great fluctuations in population.
The decline in bustard population has been blamed on the increase of the Blackbuck population from 15-20 in 1985 to nearly 500 in 2002, but this alone can not be the reason. Most of the time, the majority of the bustards remain outside the Sanctuary, where they are not safe from poachers. The goodwill among villagers generated by the development of the Sanctuary has been nullified by the crop damage caused by Blackbuck. Based on two 3-years studies, the BNHS had recommended that Blackbuck numbers should be reduced to less than 100 individuals, and poaching of bustard should be stopped, but this has not been done. Instead, the Forest Department wasted funds on the development of a fence (to prevent Blackbuck from going outside the grasslands) and on construction Increasing scrub vegetation in the grasslands (Manakadan et al. 2002) is another cause for concern, as it is reducing the bustard habitat. However, the greatest and irrevocable threat to the Great Indian Bustard is the development of a large irrigation project 3 km from Rollapadu that will change the land use and crop patterns of the area completely. In future, there will be less area available to the bustard for foraging and nesting. Therefore, it is necessary to monitor the movement of the bustards, through satellite and radio tracking, to record its use of the surrounding landscape and then to develop a long-term conservation strategy to protect pockets of grasslands where the bustards spend most of their time. A holistic approach is required to save the bustard habitat, otherwise the measures taken at Rollapadu will not succeeded in reviving the bustard population.
