The Woodlands Declaration by 50 leading scientists

Updated:

An open letter from leading scientists to Western Australian Premier Colin Barnett and Western Australian Environment Minister Donna Faragher.

An open letter to Western Australian Premier Colin Barnett and Western Australian Environment Minister Donna Faragher

We, the undersigned Australian and international scientists, write to you concerning the future of the Great Western Woodlands. Securing long term conservation is essential for this internationally important and biologically rich landscape. 

We endorse the leadership that your Government has already shown in committing to develop a conservation strategy for the region.  We encourage you to implement an effective on-ground strategy for the Great Western Woodlands as rapidly as possible. 

From the Rabbit-proof Fence, east to the plains of the Nullarbor, this intact and healthy landscape is of global ecological significance.  An area nearly three times the size of Tasmania, this 16 million hectare region is a mosaic of temperate eucalypt woodland, heathland and mallee vegetation.

It is the largest remaining temperate woodland of its type on Earth.  Once widespread in other continents, Mediterranean-climate woodlands and shrublands have become highly fragmented and degraded through clearing for agriculture and urbanization.  Less than 3% of this ecosystem is formally protected worldwide1. As a consequence, protecting this type of ecosystem is a high national and global priority for biodiversity conservation2.

Thousands of native species live in the Great Western Woodlands, many of them largely or totally restricted to the region.  It forms the largest remaining area of bushland in the south-west botanical region, a region of global ‘mega-diversity’3.  The Western Australian Herbarium has records of over 4200 plants from the woodlands. This is more than 20% of Australia’s plants in an area of less than 2% of the nation4.

In Australia, over 85% of temperate woodlands have been cleared since European settlement. The remaining areas outside the Great Western Woodlands are considerably degraded. This habitat loss and fragmentation has caused accelerating extinctions amongst wildlife5. Wildlife such as the Regent Parrot, Crested Bellbird and Carpet Python, are now regionally extinct over much former habitat across Australia.  Fortunately, these and many other species remain common in the extensive, intact habitat of the Great Western Woodlands6.   

The woodland component of the region is globally unique.  No other area of similar rainfall in the world supports woodland vegetation with trees of such size7. However, due to the low rainfall, these mature woodlands are slow growing and can take at least 300 years to develop.

Trees and soils provide a major bank of carbon in the Great Western Woodlands.  An estimated 950 million tonnes of carbon are stored their, six times Australia’s greenhouse emissions. If the woodlands are allowed to mature, free from uncontrolled wildfires and other disturbances, the region has the potential to store an additional 600 million tonnes8.  

The region is exceptional in that it has remained relatively undisturbed, intact and in good ecological health since European settlement.  However, it is now threatened by altered fire regimes, and the spread of noxious invasive weeds and feral animals9. Furthermore, the accumulated effects of road construction, mining exploration, mining and logging will cause ecological fragmentation of the region, compromising its now unique ecological integrity. 
 
Protecting the Great Western Woodlands provides a rare opportunity to invert the usual approach to conservation in Australia.  Instead of conserving biodiversity in isolated conservation parks, within a landscape dominated by human use, we can support sensitively-designed human use within a healthy landscape dedicated to conservation.

We recognise that the region is of great social, cultural and economic importance to its traditional owners, to all the people of the region, all Western Australians, and the nation as a whole.  It is a major, active mining province, has significant pastoral holdings and supports a range of other industries.  We know that its residents value the beauty and nature of the woodlands.

With good policy and strong management we believe that the future of these industries, and related economic development, can be compatible with the long term conservation of this globally significant region.

Protecting the Great Western Woodlands is of international importance. We understand that your Government is currently finalising a conservation plan for the region. 

Appropriate protective tenures and effective land management are needed to secure the biodiversity, ecological integrity, carbon stocks and the other social and economic values of the entirety of this extraordinary landscape.  Protecting and managing the Great Western Woodlands as a whole and intact functioning landscape would be a world leading, innovative, conservation solution.

We urge you to act decisively.
