 Eroding soils from degradation and increased transport of sediment from nearby runoff can transport sediments and nutrients which encourages weed growth.An example of the significance of weed invasion is the previously mentioned Blue Gum High Forest and Somersby mintbush ("Prostanthera junonis") which are susceptible to weed invasion.Pest species displace natives and alter the ecosystem functions which creates ongoing implications such as altered fire patterns and changed nutrient cycling.
