Correlations between environmental factors, the biomass of exotic annual grasses and the frequency of native perennial grasses



Correlations between environmental factors, the biomass of exotic annual grasses and the frequency of native perennial grasses



Australian Journal of Botany 54(7): 655-667



The species composition of temperate grasslands in the mid-north of South Australia has been radically altered from a system dominated by native perennial grasses to a system dominated by Mediterranean annual grasses. This study investigated the importance of chemical and physical soil characteristics, topographical features and climatic variables on the abundance of native and exotic grass species in nine ungrazed grasslands. Overall, climatic and other abiotic factors were highly variable.
