Abstract

A 1997 pilot study of Whangamata, Wharekawa, and Otahu estuaries determined that it is feasible to map vascular estuarine vegetation from aerial photography together with field surveys. The success of this work encouraged Environment Waikato to continue with this method. The estuarine vegetation of Tairua, Coromandel, Te Kouma, Manaia, Whitianga Port Waikato, Raglan, Aotea, Kawhia Harbours and the inner Firth of Thames have since been surveyed and mapped. Of these harbours, Whangamata, Otahu, Wharekawa, Tairua and Manaia have been re-surveyed to determine changes in vegetation communities over time.
