Overview
  
CREAS is a GIS-based strategic management tool for Christchurch waterways developed by ecological consultants, NIWA, and EOS Ecology. The purpose of CREAS is to provide natural asset management data of Christchurch’s waterways.
CREAS is a river survey system which will occur in several stages. The first stage includes surveys of physical habitat only carried out over three seasons. No data has been entered yet on fish and macro-invertebrates, although this will be undertaken in the near future.
