Over the past decade the excessive growth of the seagrass Ruppia megacarpa and regular Spring phytoplankton blooms have caused concerns that Wilson Inlet is becoming enriched with nutrients (eutrophication).
If the input of nutrients continues to occur unchecked then water quality in Wilson Inlet can be expected to deteriorate in a similar manner to that which has occurred in the Albany Harbours, Peel-Harvey and Swan-Canning estuarine systems.
An understanding of the nutrient sources and processes from the catchment is required to effectively manage eutrophication.
To begin to gain an understanding of nutrient inputs, a catchment monitoring program was instigated by Agriculture WA in the early 1990s.
This newsletter summarises the results of the monitoring data that had been collected to date.
