Other claims from this paper (9)
- Association Sheep showed no preference for previously ungrazed grass plants.
- Association Previously grazed grass plants were only occasionally preferred by sheep.
- Association Thyridolepis mitchelliana plants were slightly preferred over E. eriopoda plants.
- Association Landscape zones receiving water and nutrients from elsewhere were preferred for grazing, but the effect was weak.
- Association Foliage biomass of herbaceous plants near a grass plant did not influence the number of tillers grazed or the probability of the plant being grazed.
- Association Defoliation of individual grass plants by sheep was weakly determined by landscape location, stocking level, plant species and prevailing forage.
- Observation The influence of spatial and temporal variation on grazing was small.
- Observation Grazing of grass plants was random, the rule rather than an exception.
- Mechanism Spatial variability in plant mortality could be due to the combined effect of plant water stress and grazing pressure.
