Neimann Creek is a short spring fed stream meandering through the rural lowlands out into the Waimea Estuary. Much of the lowland native vegetation across the region has been removed due to farming and development. This leaves streams such as Neimann Creek vulnerable to invasive weeds (both terrestrial and aquatic), exposure to extreme temperature change and excessive nutrient run-off.
Neimann creek is a significant freshwater and estuarine ecosystem that plays an important and complex role in nutrient cycling, filtering and breakdown of pollutants from terrestrial runoff, The stream and its margins will provide habitat, feeding and breeding areas for native birds, reptiles, invertebrates, shellfish and fish, Streams such as Neimann Creek are important buffers for sea level rise, allowing flora and fauna to naturally migrate upstream to less salt induced areas.
Aim of the Project
The aim of this project is to restore and rehabilitate Neimann Creek to a functioning and healthier state. This project vision is the catchment is managed by providing fenced riparian margins of native species, weeds are removed and on-going control Is maintained. One of the biggest issues small spring fed streams have is the build of sedimentation as a result of excess nutrient input, this encourages plant growth that traps fine silts, sands and mud. An important part of this project is the removal of this accumulated sedimentation.
Some landowners have been working on removing willows and other weeds, and in some cases planting the riparian margin has begun. As funding becomes more available it will be essential to work alongside landowners and develop shared objectives.
