In vitro propagation of temperate Australian terrestrial orchids: revisiting asymbiotic compared to symbiotic germination. Botanical Journal of the Linnean Society 176:556-566. This study clearly indicates the value of revisiting germination protocols with Australian terrestrial orchid species as significant increases in germination and speed of protocorm development into plantlets was experienced with a range of orchid taxa using the new asymbiotic protocol.

29 October 2014
Dr Siegy Krauss published new research with Alison Ritchie and Karen Frick. Frick KM, Ritchie AL, Krauss SL (2014) Field of dreams: restitution of pollinator services in restored bird-pollinated plant populations. Restoration Ecology 22:832-840. Read more via an external online library.
In the baseball movie 'Field of Dreams', Kevin Costner's character is told 'If you build it (a baseball field), they (baseball players) will come'. In restoration ecology, it is largely assumed that if you put the plants back, the pollinators will come. In this study, Karen Frick et al. tested this field of dreams hypothesis for nectar-feeding birds in restored banksia woodland. They found that although bird species composition differed between restored and remnant banksia woodland, pollinator services were delivered for seed production and wide outcrossing.

The Science team undertakes integrated and innovative research in native plant biology, underpinning conservation and ecological restoration of Western Australia's unique biodiversity, and biodiversity generally. Successful conservation outcomes are achieved through world-class research and strategic alliances with industry, land managers, the community and other research organisations.
Research is focused in the key areas of restoration ecology, seed science, conservation genetics, conservation biotechnology, orchid conservation, and systematics, with a focus on extension to practitioners and land managers.
The Authority has a long history of successful post-graduate student supervision in collaboration with Western Australian universities and contributes to undergraduate teaching, predominantly in conservation biology and restoration ecology.
