Visitors are welcome, and access is free.
About the project
Rakatu Wetlands is the Trust’s largest and most ambitious project to date. This 278 ha property (purchased by the Trust in June 2000), is located, on the flood plain of the Lower Waiau River. Fiordland National Park forms the western backdrop to the property.
This article (PDF, 1.65 MB) was published in the NZ Herald in December 2019 regarding the wetland restoration’s 21st anniversary.
The vision for this property
To create an ecologically sustainable wetland/small stream ecosystem complex, for the benefit of fisheries and wildlife in the Rakatu/Redcliff area of the Lower Waiau River catchment. The complex will incorporate and link with the existing Redcliff Wildlife Reserve.
To provide public access to facilitate the public’s enjoyment, recreational use and aesthetic appreciation of the resources, and to educate and enhance the public understanding of the fisheries and wildlife habitat and the Waiau Trust’s objectives.
What’s been happening
Since owning the property the Trust has:
- protected 65ha of natural wetlands,
- created 50ha of new open water habitat
- built a new 1.4km access road
- constructed 9km of public walking tracks and associated visitor facilities
- installed and maintained a pest animal trap network
- carried out pest plant control
- monitored the ecological response to enhancement (fish and bird surveys)
- opened property to the public in 2006.
- leased some land for sheep grazing, for ongoing income
- managed and established exotic forest blocks, for income.
Wetland design to maximise habitat diversity
Creating the new wetlands was based around the natural landforms. Dams were built across drained and dewatered wetlands and across abandoned river channels. New wetlands have been linked to remnant natural wetlands.
Wetlands have long and shallow shorelines to benefit wading birds and the dabbling duck species.
Riparian margins are a mix of long/coarse vegetation, providing good cover for nesting and shorter vegetation to the waters’ edge for the open ground nesting and wading bird species.
Fish passage between all wetlands and the Lower Waiau River is provided at all times.
