It is well known that aerial game counts in South Africa are often applied in a non-standardised, unreplicated fashion. They contribute to poor management decisions based on their results as they may be subject to large statistical Type I and II errors. Replicate counts of large herbivores were conducted in a 8 500 ha sample site in the Loskop Dam Nature Reserve in July 1991. These data were used to estimate precision of the counts and estimate statistical power to detect population changes for different combinations of replications and significance levels.
