Environmental Weeds
An environmental weed is a plant that has not been declared as noxious but due to its invasive nature is still capable of negatively impacting on people’s health, native flora and fauna, local gardens and bushland.
Much like noxious weeds, environmental weeds will often outcompete natives and more desirable garden plants. Some of the vines and climbers completely cover other plants restricting their access to light and water often resulting in their death.
Some environmental weeds are garden escapees, a result of gardeners throwing green waste over the fence or birds and water spreading seeds and plants parts.
