Learning opportunities at this site

Otago Harbour is the largest feature of the ‘drowned valley’ landscape that characterises the Otago coastline. Mud flats, saltmarsh, salt meadow and shrubland bounded by rolling dunes join to form the most intact example of this type of ecosystem in Otago.

Aramoana Ecological Area is a landscape of unique character. The Aramoana Saltmarsh sits at the entrance to the harbour and includes dune slacks that make this area nationally significance.

Self-guided activites

In the notes, you'll find guidance to do:

  • sandy shore surveys - do a survey to look for changes on the shore over time
  • five minute bird counts - find and count the birds along the shore and identify them
  • an estuary survey - discovery seaweeds, plants, snails, crabs and other small animals
  • beat plastic pollution - follow this Young Ocean Explorers activity to learn about plastic pollution

  • 90 species of fish use Otago Harbour as part of their lifecycle. Including flounder/pātiki, mullet/kātaka, sole/pātiki rore and more
