Estuarine fish communities are good indicators of a range of man-made disturbances. They are mobile, relatively long lived, found near to the top of the food chain (so are affected by other parts of the chain and prone to bioaccumulation effects) and are easy to identify and return to the water: all of these characteristics make them ideal for the monitoring of estuaries. This method is based on the principle that the abundance of fish and the number of individual species found can change depending on the pressures on the estuary.

Dogwhelks are a good indicator of the contamination of the hazardous substance called tributyltin (TBT) which used to be used in anti-fouling paints on the hulls of large ships.

Saltmarshes hold great ecological value due to their range of associated plants and animals. The diversity of flora and fauna reflects the interactions between the marine and terrestrial environment.

Macroalgae are good indicators of general pressures including, toxic substances and disturbance. They are ideally suited to monitoring as many are large, widespread and relatively easily identified.

Opportunistic macroalgae are able to utilise excess nitrogen in the environment and outcompete other seaweed species. They are easy to identify and sample so are good for monitoring the effects of nutrient enrichment.

This method has been designed primarily to detect the impact of toxic substances on the distribution of certain species of macroalgae (seaweeds belonging to the group known as 'wracks', and principally members of the genus 'Fucus'').  This method monitors the upstream limit of

Benthic invertebrate communities are good indicators of organic pollution and are also sensitive to toxic pollutants. They are ideally suited to biological monitoring as they are sedentary and either feed upon sediment dwelling animals or the sediment .
