Pest plants

Vinca major © ANBG - Richardson, RG & FJ

There are 440 native plant species found in the Dandenong Ranges National Park and approximately 220 weeds species. This is a very unhealthy balance.

Weeds can prevent native plants from growing. Some animals like the Lyrebird are forced out of areas where weeds have taken over because they cannot easily move about in the forest and are not able to get the food they need.

Weeds can spread by:

  • Sticky/prickly seeds getting caught in the fur of animals or on the clothing of visitors and transported far and wide
  • The fruit is eaten by animals and the seeds are deposited in the scat/poo
  • Local residents dump their garden waste in the national park and the plants start growing
  • Wind can transport seeds from far away, like the fluffy pom-pom tops of dandelions
