Brisbane City Council spends more than $5 million each year on weed management in our natural areas, parks, waterways and road reserves.
With more than 400 invasive weed species in Brisbane and over 10 new exotic plant species becoming established each year, Brisbane's primary environmental problem is invasive plant species in our national parks. Weeds represent the second biggest threat to biodiversity after vegetation clearing.
Many species of birds are threatened by weeds and four to 10 native plant species are at risk from very serious weeds.
Residents can help by removing weeds from their land.
There are three lists of weeds declared by Council, which are then divided into three different classes depending on how severe the problem is and how easily they can be eradicated.
