The combined pressure of decreasing rainfall, changes in land-use and the use of groundwater for Perth’s water supply has impacted on the biodiverse remnant vegetation of the Perth region. Long-term monitoring of vegetation has shown changes to species composition and abundance associated with lower rainfall and drawdown in water tables. However, do the changes observed in these remnant woodlands represent a transition toward a new equilibrium between vegetation biomass and reduced water availability?
Investigations into Banksia woodland structure and function along spatio-temporal ecohydrological gradients are being conducted by ECU researchers to assist decision-making for the conservation and management of phreatophytic vegetation in this drying landscape. Relationships between groundwater availability and vegetation structure, and evapotranspiration are being assessed to identify potential future states of woodland. A response function between water availability and the productivity of vegetation will assist with the management of Banksia woodlands in a drying climate.
