Evaluating the accuracy of some commonly used game-counting methods

The accuracy of game counts on an eastern Transvaal Lowveld game ranch was examined. A drive count was
used to produce control estimates of actual population sizes. A helicopter count was more accurate than one from a fixed-wing aircraft. Twenty-four hour waterhole counts were relatively inaccurate. Line transect counts were relatively accurate when a fixed strip width equal to the mean visibility index of the vegetation was used, and when the population estimate was based on the perpendicular sighting distance. Afternoon counts were generally less accurate than morning counts, using the same technique.
