Academic background

With a number of ecological restoration projects designed to facilitate ‘best practice’ restoration of the Bold Park bushland together with major bushland restoration activities in the Kings Park bushland and a number of post-mined restoration projects, Deanna was appointed as the Senior Restoration Ecologist for the Botanic Gardens and Parks Authority (BGPA - custodian of the Kings Park and Bold Park bushlands) in 2003. Prior to this BGPA appointment, Deanna acted in the BGPA role of Senior Ecologist for 3 years. This appointment followed completion of a PhD (1996 – 1999) from the University of Western Australia, on the restoration ecology of Banksia woodlands, under the guidance of Dr. Kingsley Dixon and Prof. K. Sivasithamparam.

Deanna’s research, which has spanned 10 years, has focused on the restoration ecology, and on regenerative techniques and restoration technologies of biodiverse ecosystems throughout Western Australia, with a particular focus on Banksia woodlands. Primary foci of research has included understanding ecological processes influencing plant establishment, plant and soil relations, seed ecology, soil seed-bank dynamics, topsoil handling and storage methodologies, autecology of environmental weeds, effects of recreational activities and weed control on ecosystems, and novel restoration technologies to improve regenerative potentials of disturbed sites. While strongly based in scientific enquiry, recent research programs have been operationally focused and driven and have been pivotal in providing information of practical benefit for Deanna’s main areas of interest and expertise, namely areas where ecological restoration is a priority; post-mined sites and urban bushland areas.
