Summary
This report summarises the results of the 2008 fine scale monitoring for Waikawa Estuary, a 760ha tidal lagoon estuary on the Catlins coast, and one of the key estuaries in Environment Southland’s (ES) long-term estuary monitoring programme. This programme uses sediment health as a primary indicator of estuary condition and includes two main components, broad scale mapping and detailed fine scale monitoring. The current report describes the fine scale monitoring undertaken in February 2008 (including the measurement of sedimentation rate and broad scale macroalgal mapping) and also provides a review of the previous 3 years of monitoring data. The methods used were based on the tools included in the National Estuary Monitoring Protocol (EMP) (Robertson et al. 2002), and a number of recent extensions (Robertson and Stevens 2006 and 2008).
