Research Areas and Interests
- Hydroecology – Determining the water regimes required to maintain and enhance conservation values of terrestrial, aquatic and riparian ecosystems. In particular, water requirements of terrestrial phreatophytic and wetland/riparian vegetation.
- Management of aquatic and groundwater dependent ecosystems – Allocation planning of water resources to meet environmental requirements. Development of monitoring strategies and programmes for assessing effectiveness of environmental water provisions.
- Groundwater dependent vegetation – Impact of altered groundwater regimes on native plants at the individual, population and community level. Ecophysiology of phreatophytic vegetation and determining variability in water source partitioning. Population dynamics of phreatophytic species and response to long-term changes in groundwater regime and climate
- Ecology and biology of wetland plants - Recruitment biology of wetland tree, shrub and emergent species. Species response to altered water quantity and quality.
