Optimising seagrass restoration

About the research project

This PhD project will advance understanding of seagrass restoration opportunities in Tasmanian ecosystems, with an emphasis on improving habitat for Critically Endangered red handfish (Thymichthys politus). The research will explore key aspects of seagrass biology and physiology – particularly flowering, growth and resilience – in response to key environmental drivers such as temperature, light and nutrient availability. In doing so, it will address significant knowledge gaps that currently limit successful habitat recovery, particularly in the context of climate change and anthropogenic stressors.

By integrating field and laboratory surveys and experiments, the project will inform best-practice restoration methods at the red handfish sites and beyond. These include seedling propagation, transplanting strategies, habitat enhancement, and long-term management approaches. 

While the research is centred on red handfish recovery, the outcomes of this research will have broader applications for seagrass restoration efforts across Tasmania's coastal ecosystems. Ultimately the project aims to contribute to more effective, science-based conservation and habitat rehabilitation strategies at both local and regional scales.

Specific objectives include:

1. Investigate the influence of key environmental variables (e.g. temperature, nutrients, light) on seagrass flower development, health, and timing through controlled laboratory experiments.
2. Develop and test restoration techniques for seagrass at red handfish site(s), including seedling propagation, transplanting, habitat enhancement, and best practices for long-term meadow management and threat mitigation.
3. Identifying optimal restoration windows by analysing existing monitoring data in combination with key environmental drivers to guide timing of seagrass restoration efforts in Tasmania.

The outcomes of the project will contribute to improved seagrass restoration success and better-inform management strategies for red handfish conservation and seagrass habitat restoration at both local and regional scales.
