Feral Species

Cats

Alexandrina Council coordinates a program which aims to reduce nuisance feral cat colonies throughout the area. A large population of feral cats can very quickly impact on the breeding success of native species. 

Alexandrina Council’s cat management practices have been designed to protect the welfare of native species as well as of owned and domestic cats. 

For more information visit the animal management section on our webpage and download our fact sheets.

Foxes

Foxes were first introduced into Australia in the 1870s for recreational hunting purposes.

They have since spread to become one of our major pests and are a major problem for landholders.

The best approach to managing urban and urban fringe fox problems is to eliminate or prevent access to things that attract foxes to the area, such as easy sources of food (dog and cat biscuits, meat bones, leftovers) and daytime shelter.

Council discourages any interaction with foxes as they can carry hydatids (tapeworm) which can infect humans. They can also carry mange and other diseases that can be transmitted to your pets.

Please do not deliberately feed any foxes.

If you would like more information about foxes in the Council area phone 8555 7000 or visit the Adelaide and Mount Lofty Ranges NRM Board

Rabbits

Rabbits can have a devastating impact on our natural environment. They eat native plants and can destroy root systems when burrowing. They also compete with native animals for shelter and food and they can cause erosion by digging extensive warrens.

Pet rabbits can also become a threat if they escape from domestic back yards. Please ensure pet rabbits are kept in a safe enclosure and do not dump unwanted pets in our local reserves.

For more information please call 8555 7000 or visit the Adelaide and Mount Lofty Ranges NRM Board

Weeds 

Just like feral animals, weeds or pest plants can also have a substantial impact on our environment and our primary industries. Pest plants that can become a significant threat to our native environment, agriculture and public health and safety are called "Declared Pest Plants". Land owners, including council, have a legal responsibility to manage these plants. 

Read more about the Gazania Free Goolwa campaign and upcoming events for the initiative here.

Common weeds and declared plants in our area are:

Gazania Scabiosa

Other weeds/ declared plants include: 

Aleppo pine(d)
Boxthorn (d)
Bridal Creeper(d)
Acacia saligna
Feral Olive(d)
Victoria Tea tree
Fountain grass (d)
Three Corner Jack (d)
Acacia Cyclops
Galenia pubescens
Italian Buckthorn (d)
Scabiosa Pin Cushion
White weeping broom(d)
Pyp grass
Cape Ivy
Freesia cultivar
Montpellier Broom (d)
Bulbil Watsonia
African Boxthorn (d)
Boneseed (d)

A huge number of Australia’s weeds started out as domestic garden plants which have escaped backyards and now cause damage to our natural environment. Many invasive species are still readily available in local garden centres. Please consider buying native species when replanting your garden and please do not dump domestic garden waste in local bushland.

Human Threats 

4WD

One of the threats that our native environment faces is destruction caused by 4WD vehicles and inappropriate driving. Native vegetation and waterways can be easily destroyed when vehicles get bogged and off-road motorbikes leave designated tracks. Drivers of bogged vehicles often use inappropriate materials and methods to free their cars such as cutting down trees, destroying fences or placing rubbish under tyres in an effort to free the vehicle.

Alexandrina Council has closed and gated roads in sites where damage is frequently caused by these vehicles.

Please report destructive 4WD activities to Council by calling 8555 7000.

 Fire Wood Collection

The illegal collection of firewood from council reserves and roadsides has become a significant issue in the Alexandrina Council region.

Fallen trees, branches and dead timber provide shelter, nesting and feeding places for native wildlife and offer protection for small plants that need shelter from the elements or from grazing animals. Hollow logs and dead trees improve the natural habitats for many fauna and flora species and should therefore not be collected for firewood. Fallen leaves or bark should also be retained to stop soil erosion and minimise weed invasions.

Dead timber should not be cleaned up on roadsides, and removal is not permitted unless outlined as necessary for fuel reduction in the approved Fleurieu Interim Bushfire Management Area Plan, to assist pest control (rabbits, weeds etc.), or to remove timber which is hazardous to traffic or infrastructure. These activities are carried out with in line with this plan by authorised personnel and cannot be undertaken without the permission of Council. Illegal firewood collection can lead to vast damage on trees and habitats.

Fines apply for collecting firewood of our roadsides and Council’s Community Safety team are working together with the South Australian police to stop these environmentally damaging offences.

Illegal Dumping

Incidents of residents dumping garden or other waste on council land are unfortunately quite common, particularly in our urban biodiversity reserves and on roadsides.

Dumped waste is not only unsightly, but it smothers and kills the native plants underneath. Garden waste might seem less inappropriate; however it contains seeds and cuttings which can easily become invasive bushland weeds which out-compete native species.

Patches of natural bushland provide food and shelter for our native wildlife. Dumped waste can also flow into our creeks, rivers and beaches. Dumped items can also contain toxic materials.

rubbish

The whole community pays for the illegal dumping of rubbish. Penalties apply for persons caught illegally dumping waste on Council land.

Please report illegal dumping to Council by calling 8555 7000.
