Flow chart showing the major elements associated with bacteria and pathogen management

The vulnerability of a wetland to bacteria/pathogens is dependent on:

  • water salinity: mammalian derived bacteria generally die off more quickly in saline water
  • water temperature: mammalian derived bacteria generally survive longer in warmer water
  • water clarity: bacteria/pathogens generally die off more quickly in clearer water due to UV sterilisation processes
  • water residence time, flushing rate and dilution factors which all help determine the vulnerability of a wetland to bacteria/pathogens with longer residence times, poor flushing rates and low dilution resulting in higher levels of vulnerability

It is thought that a healthy wetland will be less vulnerable than a stressed one.
