Graders, bulldozers, tractors etc. Do not include aircraft that are only based at the site to conduct aerial surveys. Vultures are probably present, and a pool of body fluids is still moist on the ground. Carcass is now a skeleton, with clean white bones and in wet areas no skin. In arid areas some skin may be present still.
Skeletons are difficult to see from the air.
A recent carcass with intact tusks and no obvious wounds is probably dead through natural causes. Fill in table to the best of your ability. Provide additional details if available in the B8. Tusks may also be absent in very young animals. Tourists, safari hunters.
