The Friends of Mana Island Incorporated was formed in December 1998 to provide support for the Department of Conservation (DOC)in the restoration of Mana Island.
A restoration plan was prepared by DOC in 1999 and reviewed in 2010.http://www.doc.govt.nz/documents/conservation/land-and-freshwater/offshore-islands/mana-is-restoration-plan-review.pdf .
The plan called for a 20 year planting program to restore the vegetation and habitat of the Island to a similar environment to that existing prior to human intervention on the Island. The re-forestation program called for the planting of some 500,00 trees over the period.
This has been achieved. The review provides a summary of progress since 1987 and recommendations and tasks into the future.
