Site description

Vegetation

Machaerina sedgeland (WL11) and raupō reedland (WL19) wetland extends around the lagoon margins and back up the gully system behind the lagoon. The vegetation includes:

  • raupō
  • pūkio
  • jointed twig rush
  • cabbage tree
  • flax.

There are plantings along the boundary separating the lagoon from the road and estuary. On the banks surrounding the rest of the lagoon are areas of regenerating native scrub (VS5) and planted exotic trees.
