Tūhaitara Coastal Sequence

In February 2020 the Trust signed a funding agreement with DOC under their Community Fund, to restore a native forest coastal sequence in Tūhaitara Coastal Park, North Canterbury. Here is a

Summary of the project

OBJECTIVES

  • Te Kōhaka o Tūhaitara Trust and Coastal Restoration Trust will set up a demonstration site of a restored native coastal forest sequence that was typical of north Canterbury.
  • This 3-year project adds and complements the restoration work already underway by Te Kōhaka o Tūhaitara Trust and their multi-generational vision to restore indigenous coastal ecosystems supporting a diverse range of native flora and fauna species and providing sustainable mahinga kai.
  • This involves replacing logged pines and marginal pasture with foredunes of sandbinders, mid-zone coastal shrublands, wetlands and lagoons, and landward coastal podocarp forest.
  • A complete coastal vegetation sequence dominated by indigenous flora and fauna will be more resilient to expected impacts of climate change and provide an excellent demonstration area for other coastal communities and landowners in Canterbury and nationwide.

METHODS

  • We propose planting and managing a minimum 50 m wide demonstration coastal vegetation sequence linking existing small restoration areas within a high-profile part of the park.
  • This builds on the restoration work already underway by Te Kohaka o Tuhaitara including the Tutaepatu Lagoon plantings, the network of biota nodes set up by local schools and community groups, the Pines Beach wetland restoration, planting of sand dunes recently logged of pines with natives, and restoring extensive areas of recently retired pasture.
  • A minimum of 5000 native trees, shrubs, ground cover coastal and wetland species will be planted per year across the coastal sequence in collaboration with community volunteers, school and tertiary students, and local service groups.
  • Monitoring will involve setting up a series of survival and growth plots on landward sites and point sampling transects on mid and foredune sites in collaboration with volunteer community groups wherever possible supervised by Te Kohako o Tuhaitara and the Coastal Restoration Trust.
  • Vegetation monitoring will be integrated wherever possible with monitoring of fauna undertaken in the park including changes in insect, lizard, bird and fish diversity and populations over time.
  • Outputs to include guidelines on essential steps to successful restoration of a coastal flora sequence for north Canterbury and recommendations for other coastal sites nationwide.

COLLABORATION

  • Collaborating partners include Environment Canterbury, University of Canterbury, Trees That Count, Tāne’s Tree Trust, Waimakariri District Council, and numerous local community and resident associations, service groups, schools, and environmental NGOs.
