A standard set of Broad Ecosystems for the Townsville Region.
Commit to adopting a solid viable foundation that will much improve natural asset communication and reduce future information system rewriting expenses (e.g. web page) by using this standard set of 28 "Broad Ecosystems" covering the Paluma/Magnetic Island/Mt. Elliot/Charters Towers region (1:250,000 Townsville Map Sheet).
- These broad ecosystems will suit communication with the community, enthusiasts, wild asset managers, for eco-tourism and professionals in allied fields.
- A standardised ecosystem approach is critical now large information communication systems are being implemented.

- 90-95% of Townsville’s coastal plains and ranges are described by 8 broad ecosystems.
- 90-95% of the land over "The Range" are described by 8 broad ecosystems.
- Another 12 broad ecosystems fill the gaps.
- Yet these brief Broad Ecosystems are still highly useful entities.
- Understanding "Broad Ecosystems" is the simplest way to get an overview of our wild assets.
- "Broad Ecosystems" like these are far from vague concepts. Indeed the general public already think in terms of broad ecosystems, e.g. "Rainforest", "Wetlands" and "Mangroves", and already think of them as ecosystems of living things, not just plants.
Understanding "Broad Ecosystems" is the simplest way to get an overview of our wild assets.
- Importantly the same basic knowledge can be used in two completely different ways
- Can be mapped over large areas, the regional overview.
- Can assist by providing highly specific site interpretation e.g. the Alligator Creek picnic area contains elements of 3 broad ecosystems: riverine woodland or forest, Poplar Gum plains and slopes woodland and dry rainforest.

More information about a standard set of Broad Ecosystems for the Townsville Region.
These brief Broad Ecosystems are highly useful entities.
In raw form other veg types/ RE’s are far too confusing for this purpose. See regional ecosystem (RE's) map sheet example and our organisation has done that little bit extra to publish (here) the only complete index for the Queensland Herbarium Regional Ecosystem maps that cover 1:250,000 Townsville. Within Townsville City Council 70 veg types are described and the Queensland Herbarium describe 230 and 89 regional ecosystems on that map sheet.
The basis for all Townsville "ecosystems" from now on will unavoidably be the Queensland Herbarium’s "regional ecosystems"
The Queensland Herbarium have so far been only too pleased to assist with this extension of their work, printing these maps probably requires only a trivial effort by them, and the regional ecosystem basis for this and adjacent maps will continue to be modified and updated as knowledge advances.
This is one important way to bridge the gap between technologists and the huge majority of users, a major priority in all government related strategies.
Show commitment to better communication and save cost by rapidly:
Plan to use these broad ecosystems on Townsville City Council Web Page strategy
Help to educate many by promoting the use of these with all ecotourism operators
Change other relevant policies.
Write a very simple letter. The problem: three different Queensland Herbarium people will each redefine our immediate regional ecosystems to suit the average needs of 3 very different bioregions.
- Urge them to maintain this sensible broad ecosystem strategy across these immediate boundaries.
- Urge them to do their best to ensure data is maintained covering adjacent 1:250,000 map sheets that will allow us to extend and define more sensible broad ecosystems to cover the whole of the greater Townsville region.
Why this is better than other alternatives:
- The 2000 species alternative approach used by plant enthusiasts is way too confusing.
- Like many plant taxa, ecosystems are somewhat arbitrarily defined taxa. However they are defined differently for different purposes. A standard set like this is most important.
- The Townsville City Council’s mapped ecosystems are too confusing for this purpose:
- About 70 different ecosystems cover their estate divided into three sections. Each section has it’s own overlapping but different purpose, written by different people, with different definitions and names.
- A general overview of the whole "Greater Townsville Region wild assets is required with consistent simple but recognisable ecosystems both inside and outside the Council’s Boundaries.
- The Queensland Herbarium have mapped 230 RE’s for the 1:250,000 Townsville sheet. These are combined into 89 RE’s for the act’s regulations.
These "Broad Ecosystems" provide a solid framework for extending knowledge about species of interest.
- Educate by planting examples of these magnificent ecosystems side by side in public areas and schools.
- Educate with Plant CD ecosystem overviews for the community, enthusiasts, wild asset managers and eco-tourism.
- Of course species and their interactions will remain important.
- Especially educate about the interesting species examples of the various ecosystems.
- Especially provide education about the plant species that define many broad ecosystems.
- Regionally rare or threatened ecosystems are easier to visualise and appreciate than are species.
- Townsville’s Broad Ecosystems are now defined and maps can quickly become available.
- The more experienced enthusiasts can easily identify these vegetation types.
How this system meshes with the Herbarium’s strategy including Broad Vegetation Groups:
- The meeting of three Bioregions here is integral to any description of our wild assets within a statewide context. They clearly reflect our regions high bio-diversity gradients.
- But from a regional perspective the Bioregion boundaries are in fact highly diffuse and intergrade.
- These "Broad Ecosystems" fulfill a regionally very important gap in the bioregion/regional ecosystem model that very appropriately straddles the bioregion and province boundaries without any distinction.
- It is useful for this purpose to retain the set of 8 broadest vegetation groups for all of Queensland.
- But the most important level regionally, comprising the 28 broad ecosystems, are derived from: the Herbarium’s broad vegetation sub-group level:
Maintenance of this level is not a primary objective of the Herbarium and modification was required.
- 18 state system groups have been more or less adopted though the names and descriptions are more general public and locally orientated.
- 6 other state system groups are regionally insignificant.
The 12 "Eucalypt dominated" groups proposed include 10 new groups and appear especially relevant. For various reasons they do not include 10 state system groups.
