This report updates the results of the State of the Environment intertidal marine ecology monitoring programme for the Manukau Harbour between October 1987 and February 2018. The monitoring focuses on intertidal animals in mud and sand flats which form an important link between sediment and water column quality and processes, are important prey items for birds and fish, are relatively stationary and therefore representative of local conditions, and are widely used internationally for monitoring impacts on and health of ecosystems.
