Casuarina obesa in the Avon Wheatbelt Management of Native Stands and Provenance Trials

Casuarina obesa (Swamp sheoak) is generally promoted as a landcare option on saline farmland that also 

has potential as a commercial tree crop across the Avon region. The timber of swamp sheoak is suitable for 

cabinetry, furniture or firewood and recent trials indicate that can be used for CCA treated fence posts.

This native species can be planted on a range of soil types but is preferred on duplex sand over clay to heavy 

wet clays. As a seedling it is heavily browsed by stock, kangaroos and rabbits, although once more mature 

it recolonises freely and is often seen as a dense stand of between 20,000-30,000 trees per hectare on 

farmland or reserves. In time, planted sites if unmanaged will also colonise the site.
