Central Zone

In the central zone, the focus is on connecting and consolidating the remaining habitats through large scale and high-quality restoration, while also increasing the scale and effectiveness of conservation management across different tenures.

Natural values

This zone extends from the Walpole Wilderness Area across to the Stirling Range and Fitzgerald River national parks and the Ravensthorpe area, which are global icons for the conservation of Mediterranean ecosystems, and includes mallee and kwongkan systems richer in plant species than many of the world’s rainforests. Most of the botanical hotspots, within the larger global biodiversity hotspot of south-western Australia, have been mapped as within this zone. Additionally, many wildlife species, once widespread in the central and southern wheatbelt further north, are now confined to the larger vegetated habitats of this zone.

It includes the Esperance Sandplains IBRA region (including all of the Fitzgerald and part of the Recherche subregions), most of the Mallee region (including part of the Western Mallee and most of the Eastern Mallee sub-regions) and the most southerly part of the Avon Wheatbelt Rejuvenated Drainage subregion.

Threats

While some large conservation reserves remain, notably the Stirling Range, Fitzgerald River National Parks and Lake Magenta Nature Reserve (115,900ha, 330,000ha, 108,000 ha respectively), and there are still some significant habitat areas on private land, the scale of habitat loss and fragmentation is such that many species have been lost already, and the overall ecological system may be too fragmented to survive current stresses and the impact of climate change. Key stresses identified in conservation planning include changed fire regimes, the impact of feral animals and weeds, and sedimentation of river systems.

Large areas of the Gnowangerup, Jerramungup, Kent and Lake Grace local government areas were only cleared for agriculture since 1948, and some parts have proved only marginally productive except in very wet years. Such areas are relatively easy, albeit costly, to restore to biodiverse vegetation cover, and this has been demonstrated by groups and contractors working across the Central Zone in recent years. Plantation forestry is another significant land-use, particularly in the west and south of the zone.

Vision

  • Strategic Objectives for the central zone by 2030
  • All major habitats structurally reconnected through strategically placed restoration that effectively makes them one large habitat area with species and genetic material freely moving across the zone.
  • Effective on-going management support in place for main habitats across the zone so as to suppress current threats and strengthen ecological resilience in order for the bushland areas and species to require minimal ongoing management.
  • Minimal edge-effect on the core bushland/habitat areas achieved through the spread of ecologically supportive (or at least benign) land-uses surrounding them.

The Story so Far

The program started with the purchase and restoration of some initial properties strategically located between Fitzgerald River and Stirling Range national parks. Since that time a number of local groups have joined the effort, and conservation plans are being implemented across all key areas in the Central Zone. There has also been a significant increase in conservation-focused social activity as well, with a constant stream of visitors to key sites, monitoring camp-outs on property’s like the Eddy and Donna Wajon’s Chingarrup Sanctuary, and art programs and camps. This important part of the world is now on the map for its conservation values!

Achievements

Since our program began in 2002 there has been substantial progress across the Central Zone, with some 16,000ha secured for conservation and some 6,500ha restored through biodiverse plantings. There has also been a significant increase in conservation-focused activity, including control of feral cats and foxes, monitoring of how wildlife is responding to the restoration work, and a wide range of conservation awareness programs. Social justice has not been forgotten, and in 2018 plans were unveiled for the establishment of a Bush University where tertiary education will be enriched ‘Noongar way’.

Needs

We now have ‘proof of concept’ that that large scale restoration can be achieved, that local communities can benefit, and that wildlife will return. There is widespread community support for transformational change to benefit the environment, and a lot of conservation activity in the Central Zone that now has ‘a life of its own’. We have the conservation and spatial plans in place that enable us to prioritise the key next steps. So we are now working to build on this solid foundation to secure the substantial extra funding required to achieve some 20,000ha of strategically placed restoration that brings the main national parks and reserves back together.
