Catchment Environmental Monitoring Report: 2008/09

Report: TR 2010/05
Author:  Sally Grant, Claire Littler and Reece Hill

Abstract

As part of Project Watershed and Peninsula Project implementation, the Catchment Environmental Monitoring (CEM) Programme was developed to demonstrate the long term benefits of soil conservation. To date, monitoring has been established in selected priority catchments for soil conservation in the Waipa, Lower Waikato, Upper Waikato and Coromandel management zones.

The Catchment Environmental Monitoring (CEM) programme allows Environment Waikato to:

  • demonstrate the long term benefits of soil conservation and river management work programmes
  • better utilise resources and leverage opportunities to co-ordinate monitoring internally and externally (e.g. within Environment Waikato, NIWA and Landcare Research)
  • integrate new monitoring requirements into existing regional monitoring networks.

Prior to the CEM programme soil conservation implementation relied on regional monitoring information being reinterpreted at a catchment scale. However, this information is often misleading because regional scale information is being applied at a finer scale (catchment scale).

This report provides CEM programme results for the 2008/2009 year.
