Project commenced:

In this research project, Hauraki traditional knowledge concerning the harvest of oi (oi, grey-faced petrel, Pterodroma macroptera gouldi) on the Ruamaahua (Aldermen) Islands was recorded and analysed.  The harvest of oi linked Hauraki individuals to culture, ancestors, individual well-being and tribal identity.  It also maintained mana, kaitiaki responsibilities and traditional knowledge systems. Daily catch rates of oi chicks (and number of birders) have declined in some circumstances by as much as 87% between 1950 and 2007.

Traditional strategies for sustaining oi populations included: (i) selection of chicks in the intermediate stage of growth allowing those in a more advanced state to escape; (ii) harvesting chicks towards the end of the adult provisioning period to minimise disturbance; (iii) creating breeding space by splitting burrows; (iv) annual rotation of harvest around islands to enhance escapement in some years; (v) assigning partial island refuges to enhance escapement; (vi) respecting the mauri (life force) of the oi by not leaving chick remains on the islands and causing abandonment; and (vii) designating a rāhui (temporary harvest prohibition) on islands to rest colonies from harvest. Indigenous knowledge can provide valuable insights into population dynamics and strategies for managing a species, as well as to prioritise research to safe-guard the population, traditional knowledge, and cultural well-being of the harvesting community.
