The Port Phillip and Western Port region has around 500,000 ha of native vegetation which is approximately 39% of the area. The vegetation exists in more than 33,000 individual patches.
This Regional Catchment Strategy assesses the extent and quality of:
• patches of Permanent Native Vegetation; and
• the Other Native Vegetation in each Council area.
This strategy also identifies a number of Potential Nature Links. These are parts of the landscape considered to offer the most worthwhile opportunities for building and improving vegetation corridors.
The current condition has been assessed (Method) and used as the basis to set targets for the future (Targets). Lead organisations are committed to achieving these targets (Leadership) and arrangements are in place to monitor progress and success (Monitoring & reporting).
'Permanent Native Vegetation' comprises patches making significant contributions to the region’s ecological health and resilience and for which agencies or Councils are committed to keeping as native vegetation permanently.
The table below is a summary of the current condition of the patches of Permanent Native Vegetation identified across the region. For the full list of patches, click here. The patches can also be explored by using the Interactive Map.
Summary of the current condition of Permanent Native Vegetation
This assessment of the extent of Permanent Native Vegetation is used to set targets for the future (Targets). Lead organisations are committed to achieving the targets (Leadership) and arrangements are in place to monitor and report on progress and success (Monitoring & Reporting). Permanent Native Vegetation in the region can be explored on the Interactive Map.
‘Other Native Vegetation’ is defined by this strategy as native vegetation outside the ‘Permanent Native Vegetation’ patches. Other Native Vegetation is widespread in thousands of patches across the region’s landscapes. Patches vary widely in size, quality, ownership and management. The wide distribution of Other Native Vegetation makes it crucial to environmental health and resilience at local and regional scales.
'Other Native Vegetation' occurs in thousands of patches, often small and of low quality. Weed invasion, diminished regeneration, loss of understorey and low species diversity are common conditions.
The extent of all 'Other Native Vegetation' in each Council area in the Port Phillip & Western Port region is summarised in the table below. The total extent of 390,683 hectares is comprised of approximately 180,000 patches ranging from 89,000 hectares to less than 1 hectare.
Note: The data is relatively old and should be considered as a guide only. The figures do not include areas identified as Permanant Native Vegetation.

Potential Nature Links are indicative parts of the landscape considered to offer major, realistic and valuable opportunities for creating large-scale vegetation corridors and improving landscape connectivity.
Nature Links would generate north-south and east-west connections between existing habitat, enabling species transit and improving ecosystem resilience to climate change and habitat fragmentation.
The Potential Nature Links do not have precise boundaries. They are identified where there is strong potential for revegetation and other activities to improve large-scale connectivity between and around existing vegetation.
It is proposed that a relatively small number of major Potential Nature Links will be identified in this strategy so there is a focus on these links as regional priorities.
The Potential Nature Links are:
