Executive summary

This report summarises data and discusses results from a survey of soil stability (intactness and disturbance) undertaken for Environment Waikato (EW) in the year 2009.  The survey has been carried out in accordance with the National Land Monitoring Forum’s procedure for point sampling.  A previous survey was conducted for the Waikato region in 2003.  Both surveys have been undertaken primarily to provide information about soil stability (intactness and disturbance) for state of environment reporting.

The monitoring was defined by the boundaries of the area that EW has statutory responsibility for.  Within this area, soil stability was assessed at 6122 sample points, distributed at 2 kilometre intervals on the map grid, using digital orthophotos taken for EW in 2007-08.  Data recorded were land use, associated vegetation, soil stability, soil disturbance (if present), and area freshly disturbed (where present).
