Crested Grebe lake shore project
Crested Grebes have disappeared from many parts of the South Island due to introduced mammals predating on their nests. In Fiordland they have declined severely, but still today a small number of birds inhabit Lake Te Anau.
Grebes breed on the shoreline of Lake Te Anau often nesting along the 4km between the DOC office and the outlet of Lake Te Anau, building their nests on submerged branches like an anchored pontoon. Unfortunately this does not deter stoats who are well adapted to swimming a short distance for a tasty morsel.
A pathway follows along the lake edge leading people to the start of the Kepler track, one of the Great Walks of New Zealand. This area is largely made up of regenerating forest and rocky/sandy shore. Stoat traps along the shoreline benefit not only the Crested Grebe, but a range of forest birds and water fowl that also inhabit the area.
Stoat trapping presently takes place along the Kepler track. The Crested Grebe project complements this trapping network, adding protection to a wider area.
