Strakas lagoon is a large, artificially-constructed pond at the base of north-facing hillslopes in the lower Waiwera catchment. A road separates Strakas Lagoon from the adjacent Waiwera River estuary.
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:
- jointed twig rush
- cabbage tree
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.
The lagoon and wetland vegetation provide valuable habitat for a wide range of native birds including:
- weweia (New Zealand dabchick)
- pārera (grey duck)
- pāpango (New Zealand scaup)
- kawau tūi (little black shag)
- kawau paka (little shag)
- kāruhiruhi (pied shag)
- kuruwhengi (Australian shoveler)
- poaka (pied stilt)
- mioweka (banded rail)
- pūweto (spotless crake)
- mātātā (fernbird)
- matuku hūrepo (Australasian bittern).
Machaerina sedgeland ecosystem (WL11)
This critically endangered ecosystem occurs on the edges of lakes and shallow basins. It often occurs in a mosaic of wetland habitats including raupō reedland. Many native fauna species live here.
