All native plants are special to Logan. However, there are a few standout significant species that need to be highlighted for our attention. Logan City Council has developed a brochure that will help you discover the significant plant species that are found in Logan.
Twenty-one native plants are recorded in Logan as being either Near-threatened (formally Rare), vulnerable or endangered under Queensland Law, specifically under the Nature Conservation Act 1992. Ten of these species are also listed as vulnerable or endangered under the Australian Government's Law, the Environment Protection and Biodiversity Conservation Act 1999. These two forms of legislation provide a legal framework to protect and manage state and nationally significant plants and animals.
The plants in this booklet are considered significant as there are not many left in the wild. Each species has been subjected to a range of situations which has led to their decline; however, in general, there are a range of common processes which threaten their survival. These include:
- Habitat degradation through invasion of weeds and disturbance
- Loss or modification of habitat through clearing for agriculture and development
- Waterway and wetland modification, clearing, degradation and pollution
- Competition with introduced weeds
- Changes in fire regimes
- Grazing and trampling by domestic stock
- Cultivation or harvesting of seeds or fruit
- Overuse of herbicides.
Gossia gonoclada (Angle-stemmed Myrtle)
Gossia gonoclada is a plant that is classified as endangered by both the State and Federal Governments. The State Government's Recovery Plan for the angle-stemmed myrtle 2001-2005 (PDF 153 KB) lists 73 individual known parent trees within Logan and Brisbane local government areas, with 64 of these occurring within Logan. Hence Logan City Council is therefore committed to protecting this endangered species through planning scheme provisions, education, and the development of a Gossia gonoclada Recovery Plan.
As Gossia gonocladas are often difficult to find and are said to look like the common Lilly pilly (Syzgium austral), Logan City Council included Locally Significant Gossia gonoclada habitat mapping in the Logan Planning Scheme 2015 (Overlay Map -02.03 Locally Significant Vegetation Types (PDF 1291 KB)).
With the recent discovery of two new Gossia gonoclada plants outside of the previously known range, Council is undergoing a systematic review of the Gossia gonoclada Overlay Map - 02.03 Locally Significant Vegetation Types, to improve its accuracy.
With so few left in the wild, we are seeking the community's help to find any unknown and unrecorded Gossia gonocladas across the City of Logan. Council officers can then verify the sightings and incorporate their location into the revised habitat modelling to make it as accurate as possible. Council will then do it's best to manage these individual plants for the future through a Gossia gonoclada Recovery Plan.
What do Gossia gonocladas look like and where can you find them? Help us find the Endangered Angle-stemmed myrtle (PDF 5161 KB).
If you think you have found a Gossia gonoclada, please contact Council's Environment and Sustainability Branch on 3412 3412 or email email@example.com with details of your sighting.
Melaleuca irbyana (swamp tea tree)
Melaleuca irbyana is an endangered tree that is found mostly around the Jimboomba and Waterford West areas of Logan. It can form communities which are listed as critically endangered by the Federal Government.
As less than 10% of the original Melaleuca irbyana forest remains in Queensland, it is important that this species is protected into the future.
Logan's Melaleuca Irbyana Recovery Plan aims to ensure the long-term viability of Melaleuca irbyana in Logan by protecting and enhancing existing Melaleuca irbyana, and support the increase and extent of Melaleuca irbyana through research and revegetation.
Council has also produced a guideline to advise landowners on how to protect Melaleuca irbyana from development impacts.
Melaleuca irbyana PhD
Council has recently partnered with QUT to support a PhD project investigating Melaleuca irbyana.
This PhD project will deliver ground breaking research and on-ground actions to directly support the recovery of Melaleuca irbyana. For more details see the Melaleuca irbyana Project.
The first results are now available and were shared at the Ecological Society of Australia 2015 Conference in Adelaide. See the poster about the results here.
