	have introduced large carnivores which prey on ungulates such as
	kudu. Kudu occupy thick vegetation and helicopter-based counts are
	not appropriate. In this study we tested line transect counts of
	faecal pellets in conjunction with DISTANCE analysis as a method
	for assessing the abundance of kudu. Transects were undertaken in
	three regions of two game reserves and the results compared with
	helicopter based game counts (for two regions) and a known kudu population
	in the third region (an enclosed breeding centre). Estimates of kudu
	abundance were two to three times greater than the helicopter counts,
	but within the known number of kudu in the breeding centre. The increased
	accuracy in the breeding centre was probably because the transects
	covered a greater percentage of the available habitat (0.07%) than
	in the reserves (approximately 0.007%). We suggest that DISTANCE
	software and line transects counts of pellet groups can be used for
	kudu and probably for other ungulates in thicket-type vegetations.
	Accuracy will depend on the percentage of the available habitat that
	is surveyed and on the accuracy of the defecation and decay rates.},
