Abstract Researchers Jennifer Firn and Yvonne M. Buckley focus on impacts of invasive plants on Australian rangeland biodiversity and ecosystem functioning. Many of the exotic invasive species within rangelands were intentionally introduced for pasture improvement, soil stabilization, and ornamental purposes. When compared to pastures dominated by native perennial grasses, Gamba grass has been found to use three times the amount of water and to reduce the amount of water available through the soil profile. Dominance by non-native plant species is altering the natural fire regimens of Australian rangelands. Fire is a key driver of species diversity, nutrient cycling, and vegetation dynamics within Australian landscapes. Many species are adapted to fire, relying on heat, and smoke as cues for germination. There is an urgent need for restoration efforts to be re-focused on the present and the future. Invasive species are abundant and widely distributed in the rangelands. © Copyright 2010 Elsevier B.V., All rights reserved.
