Understanding Landscape Moisture Gradients to Predict Fire Impacts on Mesic Refugia. Supervisors; Dr Ryan Tangney, Nicole Willers, Sally Thompson and Fire Research Collaborators.

Climate change is increasing drought severity across south-west Western Australia, with annual rainfall declining by 15-20% since the 1970s. As landscapes become drier, mesic habitats that traditionally act as fire refugia are becoming increasingly vulnerable to fire.

This PhD project will investigate how spatial and temporal patterns of soil and vegetation moisture influence the persistence of fire refugia in the Northern Jarrah Forest. Fire refugia are critical for maintaining biodiversity, supporting post-fire recovery, and protecting fire-sensitive habitats.

A particular focus will be on mesic vegetation that provides important habitat for the mainland quokka (Setonix brachyurus), a threatened species that relies on dense riparian vegetation for shelter. The project will examine how changing moisture conditions affect the ability of these habitats to resist fire and how this knowledge can improve prescribed burning practices.

Expected Outcomes

The project will identify the environmental conditions that promote the persistence of fire refugia,



improve understanding of fire vulnerability in mesic habitats, and provide evidence-based guidance for fire and biodiversity management under a changing climate. Findings will directly inform prescribed burning strategies aimed at maintaining habitat heterogeneity and protecting critical refugia in the Northern Jarrah Forest.

Who Should Apply?

We are seeking a highly motivated student to undertake a PhD with interests in fire ecology, landscape ecology, conservation biology, environmental science, or related disciplines. The project will provide opportunities to develop skills in field-based ecological research, spatial analysis, environmental monitoring, and applied fire management while working closely with researchers and land management agencies.

Prospective candidates with strong quantitative skills and an interest in addressing real-world conservation and fire management challenges are encouraged to apply. This project offers the prospect to contribute directly to the management of biodiversity and fire resilience in one of Australia's most significant forest ecosystems.
