Invasive plant species and pests are causing problems for Queensland’s bio-security. This beautiful and bio-diverse state is under constant threat from the introduction of new plant species from horticulture enthusiasts or pest species from our busy ports and airports. Any new plant, insect or animal is considered a risk and can cause problems for the environment, local widllife and fauna. If you are a homeowner, you are responsible for the management of invasive pests and weeds on your property, whether it be an acerage in the country or a townhouse in the city. After much consultation with relevant stakeholders, experts and the general public, in February 2015 Brisbane City Council introduced the Brisbane Invasive Species Management Plan 2013-17. According to the council the main purpose of the Invasive Species Management Plan is:
The Invasive Species Management Plan helps to:
Invasive Plants Species in SE Queensland
Many invasive plant species have been introduced to Queensland by enthusiastic gardeners keen to bring variety to their gardens. There are over 1500 known native flora species in Brisbane and over 1000 exotic species that have been naturalised. However every year, approximately 27 exotic plant species are brought in the South East Queensland area and of these 12 will become naturalised. According to the strategic Management plan: ‘At last count, there were at least 400 different species of weeds and around 20 vertebrate pest animals affecting bushland, parks and waterways in Brisbane.’
Public Awareness of Invasive Plant Species.
While a passion for horticulture is admirable and can bring much pleasure to homeowners, introducing in a new species to sub tropical climate where it is likely to flourish is often damaging to the existing environment. When considering which plants to introduce to their gardens, the gardener must be aware of the long list of invasive plant species which have already been identified as problematic for the environment and aware of the problems that are caused by planting these unwelcome species into local gardens. The list of Invasive plants and pests can be found on the Brisbane City Council website or if you are unable to find a specific plant you can contact Bio-security via the council contact centre which is open 24 hours a day, 7 days a week on 07 3403 8888 for clarification.
With the Brisbane Invasive Species Management Plan 2013-17 coming to an end, its replacement is currently under construction. The new Bio –Security plans aims to ‘keep Brisbane clean and green, making our city livable and sustainable for our children and their children to follow.‘ You can download the new plan here, it make interesting reading and the council are keen to receive comments about the new plan.
