Tippera tall grass plain pastures are one of the many pasture types in the pastoral rangelands in the Kimberley region of Western Australia.

The Department of Primary Industries and Regional Development provides this pasture information as a reference for assessing pasture condition, and as a guide for pastoral station staff and others interested in the productivity and maintenance of the pastoral rangelands.

Tippera tall grass plain pastures

These pastures are part of the Kimberley sandy soil group pastures, and the perennials kangaroo grass, plume sorghum and ribbon grasses are the identifier grasses. Use the interactive key to pasture condition to help identify pasture type.

Pastoral value

Tippera tall grass plain pastures are considered to have moderate pastoral value when in good condition. Kangaroo grass has been reported to decline quickly under heavy grazing; however, these pastures appear to be quite resilient under low stocking rates in the East Kimberley. Annual grasses are considered only marginally more productive than bare ground in this pasture type.


Tippera tall grass plain pastures occur on level to gently undulating plains in wetter areas of the Ord – Victoria Plain. They occur as grasslands in eucalypt woodlands on red to yellow sandy and loamy soils. There may be patches of heavier soil within the typical sands and loams.

Pasture condition

Good: In good pasture condition, dominant species can include kangaroo grass, plume sorghum, white grass and ribbon grass. Other perennial grasses, such as black speargrass and bundle-bundle, may be present in small patches and can be scattered throughout the stand (Figure 1).

Fair: As the desirable grasses are grazed out, intermediate species, such as wire grass, become more obvious and may dominate the stand in fair condition. Threeawns and annual sorghum (both considered undesirable species in this pasture type) may begin to increase (Figure 2).

Poor: In poor condition, the space between perennial grass tussocks increases because of grazing and the stand is usually dominated by annual grasses, particularly annual sorghum. Annual sorghum is only palatable when very young, and it has little bulk and very low nutritional value after it has hayed off. Other undesirable species, such as threeawns, are often present. There may be significant areas of bare ground (Figure 3).
