                                                           Noosa Biodiversity Plan – Biodiversity Assessment Report



The following table provides a summary of the data sources, method and scoring system. The following figure provides a flowchart of the process used to
refine spatial data and assign the scores indicated below i.e. non-remnant & urban through to remnant.

                                                        industrial, commercial and community services zones from the IPZ zones layer.

* Purpose of the scoring is to provide a ranking system of all ecosystems at a broad LGA scale. It does not indicate a lack of biodiversity values within urban areas
