Abstract

As part of Project Watershed and Peninsula Project implementation, the Catchment Environmental Monitoring (CEM) Programme was established to demonstrate the long term benefits of soil conservation. To date monitoring has been established in selected priority soil conservation catchments 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, Landcare Research)
integrate new monitoring requirements into existing regional monitoring networks.

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

This report provides CEM programme results for the 2007/2008 year. The report is the second since the implementation of the CEM Programme in 2002 (see Hill et al. 2006).
