Research paper thumbnail of Removing filterable reactive phosphorus from highly coloured stormwater using constructed wetlands

Three replicate experimental ponds (15 x 5 m), were constructed to represent at a 1:1 scale a single cell from this design. Three 5 m zones of each pond were sampled: shallow (0.3 m) vegetated (Schoenoplectus validus) inflow and outflow zones and a deeper (1 m), V-shaped central zone. In 1998/99, inflows and outflow waters were intensively sampled and analysed for FRP and Total P. In addition, all major pools of P (plants, sediment) within the ponds, and important P removal processes (benthic flux, uptake by biofilm and S. validus) were quantified. A removal efficiency of 5% (1998) and 10% (1999) was obtained for FRP. Initial uptake was mainly in plant biomass, although the sediment became an increasingly important sink. Benthic flux experiments showed that anoxia did not cause release of P from sediments, indicating that most of the P was bound as apatite rather than associated with Fe or Mn. The highly coloured waters were believed responsible for the very low biofilm biomass recorded (<1 g x m(-2)). We have demonstrated that constructed wetlands can be effective for removing FRP immediately after construction, although their long-term removal capacity needs further research.

Research paper thumbnail of Phreatophytic vegetation responses to groundwater depth in a drying mediterranean-type landscape

Can alternative states of phreatophytic vegetation be identified, and do they persist despite a multi‐decadal drying of a mediterranean‐type landscape? With reduction in rainfall and increased used of groundwater resources, ecosystem managers may question whether plant hydrotype composition of phreatophytic vegetation alters with drawdown of the water table. In this paper a data set spanning 35 yr was used to determine the alternative states of phreatophytic vegetation and how they relate to spatial variation and temporal change in hydrological habitat.
