The Healthy Estuary and Rivers of the City: Water quality and ecosystem health monitoring programme of Ihutai was written in 2006 and published in February 2009 after being updated. It includes monitoring programmes for the 4 environmental values.
2008 Reports
These reports (R09/82 - R09/85) summarising 2008 data cover aspects of water quality of the Avon-Heathcote Estuary and rivers, river habitat and its biota and the soft sediments of estuary and tidal reaches. They complement the 2007 data reports (R08/43 - R08/47) which also include one on metal concentrations in fish and shellfish. Reports including more detailed analysis, such as analysis of trends over time, will be produced following 5 years of data collection.
