Description

This paper describe.s some of the spatial variation in microclimate,' soils and vegetation across the black speargrass (Heteropogon contorus) grazing lands of south-east Queensland. Differences in the establishment and survival of oversown legumes, and in animal production', associated with this variation were examined in a large­scale grazing trial. The consequences of spatial heterogeneity are discussed in relation to species evaluation, restoration of degraded grazing lands and the development of sustainable grazing systems.

Management and Use of Complex Landscapes: Some Implications of Spatial Variation for Pasture and Animal Production
