Resource depletion and association increases in interspecific competition are likely to influence differential habitat usage amongst a guild. We tested some prominent theoretical concepts using observed differenced in seasonal habitat use amongst the savannah browser guild (elephant, giraffe, impala, kudu and nyala) in Hluhluwe-iMfolozi Park, South Africa. Herbivore locations (n= 3108) were recorded over 2 y using repeated road transects and, for elephant, GPS collars (187254 downloads). Densities were calculated using a novel GIS approach designed to be a cost-effective
