PROJECT
INTERESTS

With a focus on Australian native seeds Lydia investigates seed conservation biology, threatened species conservation, endangered species and communities, seed ecology, seed dispersal, seed physiology, ecophysiological germination thresholds, stress tolerance, and landscape restoration.
Specifically:

  • Researching the ecological factors that drive germination and dormancy, and the effects of environmental stress on seed dispersal, germination, and establishment.
  • Interpreting and applying seed ecology, biology and stress physiology results to more effectively use seed bank collections for restoration and reintroduction of rare and threatened plants or communities, with regard to resilience under future climate conditions.
  • Conserving Australia's plant diversity, including rare and endangered species of the Australian Alps, ACT region and Commonwealth Terrestrial Parks, through ex situ conservation methods, namely seed banks and living plant collections.
  • Improving the collection methodology, genetic diversity and utility of seed bank collections.
  • Investigating the storage biology of seeds to inform collection management.
  • Applying methods and technologies that are new to seed science research.

The Seed Conservation Biologist plays a key role in developing and monitoring the strategic direction and scientific goals of the National Seed Bank at the Australian National Botanic Gardens and expanding existing seed banking and research activities.

CURRENT
RESEARCH
PROJECTS

Lydia is undertaking a number of collaborative conservation and research projects which aim to secure collections and develop protocols to germinate seeds of threatened plants, or plants of threatened communities. Particularly, she is focusing on the EPBC listed community of ‘Alpine Sphagnum bogs and associated fens’ and the germination ecology and seed persistence of plants that form this community.
