Although the park has succeeded in restoring the rhinoceros population, the rhinos' food supply is diminishing because of grazing by park elephants and livestock owned by the people who live in the park.
Illegal grass cutting further reduces the rhinos' food supply.
Rhinos require large quantities of food, and they have turned to crop feeding to supplement their diet. The people who live in the park complain of crop damage and attack. Having relatively small home ranges and travelling in small numbers, it is not difficult to identify the rhinos involved in crop damage. Quantification of crop damage was made by local farmer interviews, discussions with park staff and hotel owners, and actual measurements of damaged cultivated area. The cultivated area was divided into three zones.
