Lechwe habitat use was studied intensively for 2.5 years and monitored for a further 7.5 years in the Linyanti Swamp, northern Botswana. It was found to be highly selective with respect to both resting and feeding sites. The selection of resting sites was probably a function of predator avoidance behaviour, while the selection of feeding sites was probably a function of pasture quality. The results of the study were consistent with the argument of IIlius & Gordon (1987) that sexual segregation of feeding sites is due to allometry of food intake and with the contention of Jarman (1974) that social factors may also affect habitat use.
