White-faced storm petrel translocation project 2019-2021
In 2019 FOMI began translocating white-faced storm petrels / rōrō, takahikare-moana from Rekohu / Chathams to Mana Island over a three-year period. The aim is to transfer up to 50 chicks in 2019, and 100 each in 2020 and 2021. This work is made possible through funding from our major sponsor OMV New Zealand Ltd.
To establish a self-sustaining population of white-faced storm petrels / rōrō, takahikare-moana on Mana Island – to help restore the cycle of nutrients from sea to land, and improve the habitat for other animals and plants.
This translocation is part of the ongoing restoration of Mana’s original ecosystem based on a plan developed by DOC in 1999.
Conservation outcomes – short to long term
- To have translocated up to 250 WFSP chicks (one cohort of up to 50 and two cohorts of 100 each) by Feb 2021, with at least 238 fledging in healthy condition.
- To have at least 15 pairs of WFSP breeding on Mana Island within 10 years.
- To have a growing population of WFSP on Mana Island that exceeds 50 pairs and has demonstrable ecological benefits to other species on the island, within 30 years.
This project is managed by FOMI. The chicks are selected by wildlife biologist Cathy Mitchell and DOC staff, from the source island – Rangatira / Hokorereoro / South East Island in Rekohu / Chathams.
Representatives from Hokotehi Moriori and Ngāti Mutunga travel with the birds from Rekohu and formally hand them over to Mana Island local iwi Ngāti Toa.
Trained volunteers, led by Cathy Mitchell, feed the chicks for up to three weeks on Mana Island, until the birds fledge.
Progress to date
Translocations of 48 and 98 chicks were successfully completed in 2019 and 2020. The final translocation of 100 chicks is planned for February 2021.
