Dr Bunn is the Team Leader for the Conservation Biotechnology group at Kings Park and is actively involved in tissue culture propagation of Australian native plants, primarily for ex situ conservation and restoration of endangered plants and for restoration of recalcitrant plant species in disturbed habitats, but also for selected horticultural purposes. The Conservation Biotechnology team are involved in a range of research programs with the aim of providing new, efficient and innovative ways to enhance in vitro propagation of Australian plants, provide critical micropropagation research for endangered plants and ultimately conserve endangered plants and specific plant taxa that are difficult or impossible to propagate by conventional methods. Key areas of research include somatic embryogenesis, cryogenic storage and enhancing the resilience and survival of micropropagated plants under high-stress environmental conditions. Dr Bunn is adjunct lecturer at The University of Western Australia in conservation biology and is an Associate Editor for In Vitro Cellular and Developmental Biology, Plant (IVP). He is also Adjunct Prof (Botany Dept) Kasetsart University, Bangkok, Thailand.
- ARC Linkage project (LP0561956), Em/Prof JA McComb (Murdoch University); Dr E Bunn; Dr KW Dixon (BGPA). ‘In vitro propagation (through somatic embryogenesis) of rush and sedge species important for land rehabilitation’. Total of $220,000 over 3 yrs. Partner Organization(s): Botanic Gardens and Parks Authority, Worsley Refinery, Seed Solutions (Administering Institution: Murdoch University)
- Investigation of in vitro propagation methods for initiating culture lines of selected rush and sedge species for mining restoration (short-term project, Worsley Mining (WAPL).
- Micropropagation of plants of Synaphea stenoloba, a critically endangered species from the Pinjarra district. The plants being produced by Kings Park are part of a collaborative project involving Kings Park, ALCOA, UWA and CALM, to firstly, establish ex situ collections of tissue cultured plants, followed by micropropagation of plants for the future recovery of this very rare species.
- Micropropagation of plants of Symonanthus bancroftii (‘Bancroft’s Symonanthus’), a critically endangered species from the Bruce Rock district. The plants produced by Kings Park are part of a translocation project to restore populations of this extremely rare species to the natural habitat. This is a collaborative project between Kings Park, CALM (Narrogin District), Bruce Rock LandCare, Bruce Rock Shire and local volunteers. This project has received funding support from World Wildlife Fund (WWF) through a Threatened Species Network (TSN) grant in 2003 and 2005, administered through Bruce Rock LandCare.
- Micropropagation of plants of Synaphea quartzitica (‘Quartz loving synaphea’), a critically endangered species from the Moora district. The plants being produced by Kings Park are part of a collaborative project involving Kings Park and CALM (Moora District), which has so far resulted in successful establishment of ex situ collections of tissue cultured plants. Micropropagated plants have been planted in the field to facilitate a pilot reintroduction project in 2005. This project is aimed at preventing the extinction of this extremely rare species.
- Micropropagation of plants of Grevillea scapigera (‘Corrigin grevillea’), a critically endangered species from the Corrigin district. Plants of the Corrigin grevillea produced by Kings Park have been translocated to field sites near the hinterland of Corrigin and new populations have been successfully restored to the natural habitat. This project is a collaborative project comprising Kings Park, CALM (Narrogin District), Corrigin LandCare and local volunteers.
- Cryogenic research is continuing with new species undergoing screening for cryostorage potential. This is an ongoing program with the aim of placing key germplasm samples of critically endangered plants into long-term cryogenic storage. The cryogenic methods developed by Kings Park were the first such studies for indigenous Australian plants (Touchell et al, 2002a, 2002b).
- Investigation of in vitro propagation of endangered plant species continues to be a primary research program and is aimed at critically endangered taxa in urgent need of ex situ conservation and where other (conventional) means of propagation are not feasible.
