Impacts of changing fire regime, specifically season and severity on Australian flora.

Fire is a major driver to plant population dynamics across Australia. Changes to the fire regime can be detrimental to plant persistence. Most research in this space has been focused on altering fire frequency. My research will focus on an understudied aspect of fire, changing fire season and increasing fire severity.

My current research aims to answer:

  • How does shifting fire season affect terrestrial orchid species? Does phenology, root structure and particular mycorrhizal relationships in different orchid species change the effects of fire seasonality?
  • In response to the 2019/2020 Australian summer fires, how does increasing fire severity impact serotinous seedbanks in Australian Proteaceae and Myrtaceae species?
