Estimating the trends in herbivore numbers in the Southern District of the Kruger National Park

Abstract

Census data over several years of survey were utilized to develop a sampling strategy in which the species totals for both abundant and rare herbivore species can be estimated with aerial sample surveys. Correspondence analysis is used towards the development of this sampling strategy. Census data from 1977 to 1989 were used. It is shown that the trends indicated by the census data are also clearly evident from the estimated totals. -Author
