Description
Environment Canterbury’s Regional Policy Statement (RPS) includes objectives to protect the indigenous vegetation and habitat of Canterbury’s high country. The spread of wilding trees can result in the replacement of indigenous vegetation with exotic forest. Monitoring of wilding tree spread in the high country allows us to calculate the extent of spread and is useful in prioritising control operations.
Defined high country catchments were searched over the periods 1998-2003 and 2008-2013. The areas were surveyed from formed roads and farm tracks, and the location of wilding trees was also determined from discussions with landowners and Department of Conservation Rangers. Trees that were further than 200 m apart were recorded as Individual Outlier Trees, while trees closer than 200 m were recorded as Outlier Groups.
