 The oribi occurs in a variety of habitats – from savannahs , floodplains and tropical grasslands with 10 – 100 centimetres ( 3 @.@ 9 – 39 @.@ 4 in ) tall grasses to montane grasslands at low altitudes , up to 2 @,@ 000 metres ( 6 @,@ 600 ft ) above the sea level . Recently burnt areas often attract groups of oribi . The choice of habitat depends on the availability of cover needed to escape the eyes of predators . Population densities typically vary between 2 and 10 individuals per km2 ; however , densities as high as 45 individuals per km2 have been recorded in tropical grasslands that receive over 110 centimetres ( 43 in ) of annual rainfall and open floodplains . The oribi 's range overlaps with those of larger grazers such as the African buffalo , hippopotamus , hartebeest , Thomson 's gazelle and topi . These separate species often occur in close proximity to each other , increasing predator vigilance .
