Cabomba

This week's weed is a water weed commonly known as Cabomba. It's classified as a RESTRICTED invasive.

WHAT TO LOOK FOR

  • Perennial fully submerged aquatic plant rooted at depths of up to 3m (can grow floating)
  • Leaves are brown-green feathery & fan-shaped, oppositely arranged along stems up to 10m in length
  • Flowers are white about 2cm across, appearing above the surface on a short stem
  • Soft and slimy to the touch
  • Prefers ponds, dams and slow moving waterways

WHY IT'S BAD

  • Aggressive grower forming dense canopies just below the surface, displacing native water plants
  • Affects water quality, siltation levels and water flow
  • Impedes access to water by stock, wildlife and human recreation (entanglement)
  • Easily spreads and reproduces by stem fragments in flood waters, on recreation craft and animals
  • Potentially spreads in illegal aquarium plant trade

WHAT TO DO

  • Report to GRC for advice on immediate control
  • DO NOT give it away, sell it, or release it into the environment. Penalties may apply.
