A weed is any plant considered to be unwanted in an environment. They often prevail over native plants, impacting on environmental diversity, agriculture and our community.
Where weeds come from
Many environmental weeds are introduced from overseas. Over 70% of our weeds have been introduced for agricultural purposes or as garden plants.
With their predators and natural controls left behind, these plants often thrive and quickly outcompete our local species.
Australian native species can also be problematic when moved outside of their natural range.
Problems caused by weeds
Habitats in the Redlands Coast ranging from riparian rainforest to coastal wetlands, are home to a great diversity of plants and animals. This diversity is being threatened by environmental weeds.
Environmental weeds impact our community through:
- Outcompeting native plant species
- Damaging and changing native landscapes
- Impacting on the value of habitat for native wildlife
- Increasing the risk of wildfire
- Toxicity to people, livestock and pets
- Choking waterways and causing erosion
- Reducing our enjoyment of local reserves, parklands, waterways and beaches.
