The Southwest of Western Australia is a global biodiversity hotspot that has been extensively cleared since European settlement resulting in the widespread fragmentation of native vegetation. The large-scale decline of Banksia woodlands along the Swan Coastal Plain (<30% remain) has warranted their listing as an ‘Endangered Ecological Community’ under the Commonwealth EPBC Act 1999. The woodlands have been lost from the central part of their range due to urban development and their northern range due to the establishment of exotic pine plantations and sand mine extraction. 

 Hanson is world leading in ecological restoration practice, however there are still targeted developments that need to be addressed. The use of seed is one, with >90% of seed used in restoration programs fail to establish into mature plants. This project aims to reduce these failure rates through investigating and developing seed enhancement technologies to overcome barriers to restoration success. Combining seed-based enhancement technologies with ecologically-guided engineering applications in a biodiversity hotspot is a novel and rapidly developing field. 

 This project will significantly advance the on-ground practice of ecological restoration, contributing to the knowledge and development of economically efficient solutions to improve native plant establishment success rates that will have global relevance.

Seed science tools : Seed cleaning

Tools used in seed cleaning - a zig-zag aspirator is used to remove dust, chaff, husks and material (lighter than the seed) away from the seed we want. This is one of the processes we call 'seed cleaning'.

Sharing research at the Society for Range Management Conference in early February

Colleague and team member Dr Todd Erickson and I recently attended a Rangeland management conference in Nevada USA ( where we met up with The Nature Conservancy group from Oregon - here is a link to a summary of work they are carrying out using the same seed enhancement technologies we are investigating at Gaskell in Perth.
