Integrated Catchment Management

Integrated Catchment Management for the Motueka River

"From ridge tops to the sea"

Welcome to the ICM Motueka Research Programme web site. Its purpose is to provide information resources relevant to project participants and to the stakeholders of the Motueka River catchment. The site is a collaborative venture between a number of organisations.

It was an 11 year programme which commenced in July 2000 and concluded in September 2011, and whose goal was to conduct multi-disciplinary, multi-stakeholder research to provide information and knowledge that will improve the management of land, freshwater, and near-coastal environments in catchments with multiple, interacting, and potentially conflicting land uses.

The site will continue to contain items relevant to ICM but is now largely a legacy site.

The Motueka River catchment is a Global HELP Catchment.

 

Research highlights - Tracing Sediment from the mountains to the Bay

The March 2005 flood that was centred in the upper Motueka River catchment eroded significant amounts of sediment from a mineral belt region known as the Red Hills. These sediments were flushed into and through the main stem of the Motueka River with considerable amounts finding their way out into Tasman Bay. By investigating the concentrations of these metals in River margin sediments, Reid Forrest and Paul Gillespie were able to show that the flood moved sediments from the Red Hills into and through the main stem of the River. The relative proportion of the various metals in Tasman Bay sediments provided a useful ‘signature’ for identifying the spatial extent of the influence...
