| Don't plant trees with deep roots, especially invasive species such as willows. |
| After habitat destruction, the spread of alien invasive species in our countryside is one of the most pervasive threats to our native plants. |
| Rapid phenotypic changes are expected to occur in invasive species in response to new environmental conditions. |
| The present serious damage to biodiversity comes from conventional invasive species like woody species, lantana, bugweed and pompom. |
| The invasive species kill birds, small marsupials, amphibians, lizards, and snakes. |
| But since the plant's seeds are sterile, the grass does not spread like an invasive species. |
