Native Plants

Logan City's main vegetated areas are the Daisy Hill Conservation Park, Carbrook Wetlands in the east of the City, Greenbank Military Training Area in the west and Plunkett Conservation Park in the South-East.

Of the 957 square kilometres of land governed by Logan City Council, approximately 268 square kilometres is designated as remnant vegetation under the Vegetation Management Act 1999. The different vegetation types (known as Regional Ecosystems) are broken down into categories depending on the amount remaining within Queensland. In Logan 12.9% of this Remnant Vegetation is classified as Endangered, 53.2% as Of Concern and 33.9% as of Least Concern.

Benefits of native plants

Native plants play a large role in maintaining the biodiversity of both flora and fauna in Australia. Some of the many benefits associated with planting native species include:

  • Plants that grow naturally in your local area will be well adapted to the local soil and climatic conditions of the area hence they will often grow where nothing else will (e.g. boggy areas).
  • Some native plants have well developed root systems and so can assist in stabilising soil.
  • Native plants will also be able to tolerate local climatic extremes such as frost or periodic drought.
  • Native species of plants will provide the right habitat and food for native animals, birds and insect populations.
  • They will often grow faster and hardier than exotic species and be less susceptible to local pests and diseases.
  • They provide shade and can help modify local temperature extremes.
  • Native plants are easily established and maintained.
  • They will not develop into an ongoing weed problem like some exotic plants.

The habitat values of native plants

Native plants provide crucial habitat for many species of Australian animals such as birds and arboreal mammals. Over 50 species of birds (owls, parrots etc) and over 95 species of mammals utilise tree hollows for shelter and safety. While hollow formation in eucalypts can begin from a young age, recent evidence has shown that hollows suitable for vertebrate fauna (birds, mammals, reptiles, amphibians) do not occur before the age of 120-180 years. Large hollows will take at least 220 years. Dead and fallen trees also play a vital role in providing habitat for animals as well as maintaining forest and woodland nutrient cycles. The removal of dead wood for firewood can have a significant impact on wildlife and ecosystem function.

The value of an understorey

The understorey is often overlooked as an important part of the natural ecosystem. The sub-layer of canopy known as the understorey includes shrubs and small or juvenile trees that occupy vegetation layers below the canopy of taller/mature trees. The understorey provides many natural functions in the environment including:

  • Natural weed control;
  • Wildlife habitat (protection for smaller species in the food chain);
  • Encouragement of smaller woodland birds, many of which are disappearing;
  • Protection and enrichment of the soil;
  • The ability of some species to fix nitrogen into the soil assisting other species to grow (e.g. wattles);
  • The maintenance of biodiversity and genetic resources;
  • Ensuring a suitable environment for regeneration of canopy trees; and
  • Aesthetic values.

It is important to conserve what understorey remains as it represents 90% of native plant biodiversity and impacts directly on the types of wildlife residing in your area.

Logan's bushland areas

Many of Logan's natural bushland areas are public accessible parklands. These parks are a great place to have a picnic and take a discovery bushwalk. As well as providing active recreation areas, bushland parks also provide important habitat for our plants and wildlife. Visit the Parks Directory for a full listing of all parks in Logan.

Vegetation located on Council's bushland areas is protected under Council Local Law No. 5 (Use and Protection of Parks).

Significant trees 

Council encourages the recording of significant trees within Logan. A significant tree may have historic and/or natural value, botanic/scientific value, social, cultural and commemorative value or visual and aesthetic value.

Council keeps a register of significant trees on Council-owned land. If you wish to nominate a tree on Council-owned land for the register, please complete the Nomination Form (PDF 27 KB) and send to:

Trees Section, Marsden Depot
Logan City Council
PO Box 3226
Logan City DC  QLD  4114

If a significant tree has been found on private land, please nominate it for the National Trusts of Australia Register of Significant Trees.
