Thesis topic: Lake Rotokakahi - the kakahi in a general framework of lake health

Under the supervision of David Hamilton, Joseph investigated the current health condition of Lake Rotokakahi and factors relating to the observed declines in kakahi. His rationale for chosing this topic stemmed from his affliliation to the hapu who hold guardianship over Lake Rotokakahi and have observed declines of a culturally important species the kakahi or freshwater mussel. His work involved monitoring lake profile variables, surveying kakahi populations and developing a written history of Lake Rotokakahi based on oral histories and limited published material. This research will contribute to enhancing Hapu and Iwi applied management strategies over culturally significant waterbodies. Accordingly, they will have more proactive roles as kaitiaki over lakes streams and rivers.
