Abstract

Studied the effects of soil nutrient status on degradation of roadside vegetation in the wheatbelt of Western Australia. Road verges in the Kellerberrin district are severely affected by nutrient enrichment from adjacent agricultural areas. In road verges dominated by mallee Eucalyptus erythronema the percentage cover and diversity of exotic species of annuals and perennials show significant increases that correspond to increases in soil P. Nutrient enrichment may increase the percentage cover of native species, but may also increase the competitiveness of exotic species, and so ultimately be to the detriment of the native species. Insect defoliation of E. erythronema in road verges (10±1%) were low compared to the findings of other studies. Defoliation levels within reserves (8±1%) were not significantly different to those in road verges. Recommendations for methods to reduce nutrient enrichment are discussed. -from Authors
