As we were finalising our 20 year Master Plan in 1997, we could see the advantages of GPS/GIS mapping of our plants and structures for all sorts of management values, especially monitoring change. Whether it was an icon like the famous Separation Tree, which featured in celebrations of Victoria's parting from New South Wales in 1851, or the surviving quaint Colonial shelters, which seem part of our collective memories, the potential was enormous. In 1997 the capture of more than 50,000 plants of 12,000 different species started using a differential GPS. We were able to upgrade to ArcView 9 this year after we obtained an ESRI conservation grant.
