In the 1990gass, Environment Southland (ES) established a long-term monitoring programme to assess some of the major issues faced by New Zealand estuaries using the tools included in the National Estuary Monitoring Protocol (EMP) (Robertson et al. 2002). The programme, being undertaken in a staged manner in Southlandgass key estuaries, includes Waituna Lagoon (1,350ha), and its associated wetland (~2,200ha), centred in Toetoes Bay in Eastern Southland. Waituna Lagoon has been identified as having a high risk of nutrient, sedimentation, pathogen and, to a lesser extent, habitat loss problems (Johnson & Partridge 1998, Thompson & Ryder 2003, Cadmus & Schallenberg 2007, Schallenberg & Tyrrell 2007). ES contracted Wriggle Coastal Management (Wriggle) to undertake an Ecological Vulnerability Assessment (see Stevens and Robertson 2007) to determine monitoring and management priorities, and a series of monitoring studies in February/ March 2007 to provide a baseline against which change can be measured. The present report summarises the results of the 2007 monitoring for Waituna Lagoon. - Overview
