Validating the extent of modelled "rare and vulnerable forest ecosystems" identified during the Southern CRA (1997-2000) was required for ecologically sustainable conservation management of reserves within the NPWS South Coast Region. The validation was for 47 forest ecosystems out of a total of 96 forest ecosystems that occur in the NPWS South Coast Region. Considerable improvements were made to the reliability and accuracy of the vegetation ecosystem map. Some 3000 edits were incorporated into the revised forest ecosystem map. Six new ecosystems were newly classified as part of this contract. VIS_ID 4155
