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
  1. Can be mapped over large areas, the regional overview.
  2. 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.

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.

Why this is better than other alternatives:

  1. 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.
  2. 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.

These "Broad Ecosystems" provide a solid framework for extending knowledge about species of interest.

How this system meshes with the Herbarium’s strategy including Broad Vegetation Groups:

  1. 18 state system groups have been more or less adopted though the names and descriptions are more general public and locally orientated.
  2. 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.
