Appendix 5: Threatened Species and Ecological Communities Density Grids

The Threatened Species Density Grids (1km grid squares), developed for the South Coast Regional Strategic Management Plan (Gilfillan et al. 2009b) were used to map the distribution and density of records of threatened and priority species and ecological communities in the Fitzgerald Biosphere (Section 4.2). In the interpretation of these grids, consideration needs to be given to uneven survey effort across the Biosphere, in that some patterns of distribution may be more representative of survey effort rather than the actual distribution of species.


The Threatened Species Density Grids for threatened and priority flora and fauna, and for ecological communities are shown in Figures 8 to 12. Records of both threatened and priority flora and fauna are scattered across the Biosphere, with concentrations in the FRNP and Ravensthorpe Range. For flora this reflects that these are hotspots within the biosphere containing high species diversity and endemism. The only threatened ecological community (Eucalyptus acies mallee heath) occurs in the Fitzgerald River National Park, while the priority ecological communities are primarily in the Ravensthorpe Range.

Figure 9: The distribution and density (number of species) of PRIORITY FAUNA across the Fitzgerald Biosphere, displayed using a Threatened Species Density Grid (1km grid squares).
Figure 10: The distribution and density (number of species) of THREATENED FLORA across the Fitzgerald Biosphere, displayed using a Threatened Species Density Grid (1km grid squares).
Figure 11: The distribution and density (number of species) of PRIORITY FLORA across the Fitzgerald Biosphere, displayed using a Threatened Species Density Grid (1km grid squares).
Figure 12: The distribution and density (number of communities) of THREATENED and PRIORITY ECOLOGICAL COMMUNITIES (TEC and PEC) across the Fitzgerald Biosphere, displayed using a Threatened Species Density Grid (1km grid squares). The only TEC in the Biosphere, Eucalyptus acies mallee heath, occurs on Thumb Peak, Mid Mount Barren and Woolburnup Hill (the grids near the coast in central FRNP).


Appendix 6: Miradi Criteria

Analysis and rating of the risk of the threatening processes on the threatened species and ecological communities was completed with the Open Standards of the Practice of Conservation guidelines and using the adaptive management software Miradi (CMP 2009). This analysis and ranking was completed by DEC staff Sandra Gilfillan, Sarah Barrett, Sarah Comer, Tony Friend and Janet Newell, based on best available knowledge and the current understanding of the impacts of individual threatening processes on threatened species and ecological communities.


The ratings are was based on the following three criteria (WWF 2007):

The Miradi software (CMP 2009) calculates the risk ratings using the below rules to first combine the Scope and Severity variables to get a Threat Magnitude, which is then combined with Irreversibility to get the ratings.

The summary risk ratings are calculated in Miradi by using a combination of rules for rolling up ratings across species/communities and threats.


  • 3-5-7 Rule

3 High rated threats are equivalent to 1 Very High-rated threat;

5 Medium rated threats are equivalent to 1 High-rated threat;

7 Low rated threats are equivalent to 1 Medium-rated threat


  • 2-Prime Rule

After the 3-5-7 rule has been applied, the 2-prime rule is used to determine the rolled up rating for a target, a threat, or for the whole project. This rule requires the equivalent of two ratings at a certain level for the end result to be that level.

  • Majority Override

The Majority Override rule ensures that the overall rating is not reduced too much by the other rules. Normally, the overall rating is a rollup of the threat ratings, using the rules above. However, if a majority of the targets have a rating higher than that computed rollup, then that majority rating is used instead.

Appendix 7: Threatened Species and Ecological Communities Action Summary

This table summarises which recovery actions address the management and recovery of each of the threatened species and ecological communities. Regional actions (e.g. Action 1) that are relevant to all the species and communities are not included in this table.
