Climate change is expected to cause extinctions when native plants and animals are prevented from migrating out of their hotter or drier habitats to more suitable climates. But for many species a more

Cane toads introduced to Queensland in 1935, are major environmental pests in Western Australia, having arrived here in February 2009. The Liberal National Government released a 10-year Cane Toad Strategy for Western Australia in 2009.

Invasive species compete with endemic species and if successful can displace native species in the host region (Cororaton et al., 2009).

In tropical forests, natural disturbance creates opportunities for species to claim previously utilized space and resources and is considered an important mechanism in the maintenance of species diversity. However, ecologists have long recognized that disturbance also promotes exotic plant invasions. Cyclones cause extensive defoliation, loss of major branches and multiple tree falls, resulting in a significantly more open canopy and increased light and heat levels in the understorey.
