Threatened Species

Regional Vulnerability Groups

Six groups representing regional vulnerability to decline were developed separately for flora and fauna species included in this plan. and present the species’ Vulnerability Group membership, Sub-regional priority, preferred BVG, level of knowledge and regional threat ratings.

Group 1 represents higher priority species while Group 6 represents relatively lower priority species (note that this is in the context of all of these species being identified as regional recovery priorities). Due to uncertainty in the data and available information as described in Section , group membership should not be considered completely discrete or absolute. For example, in reality there may be insignificant differences between species vulnerability in adjacent groups. The results from this assessment are combined with a variety of other analyses and presented in the following sections.

Threatened flora species presence by Sub-regional Landscape

The Fleurieu Sub-regional Landscape is very species-rich (in terms of the threatened flora species included in this plan), having over half (54 per cent) of the flora species present (). The majority of these species are ‘Wetland’ species. Importantly, the Fleurieu SRL also has by far the highest number of SRL endemics. Some SRLs are relatively small but have comparatively high species occurrence, including Southern Coastline, Foothills/Hills Face and Central Lofty Ranges. The Southern Coastline also has relatively high SRL endemism.

Threatened fauna species presence by Sub-regional Landscape

Compared to the flora species’ distribution, in general fauna species are more evenly spread throughout the SRLs (). There is also much less SRL endemism compared to flora species. However, some SRLs are relatively small in area but have comparatively high species occurrence, including Southern Coastline, Foothills/Hills Face, Northern Lofty Ranges.
