Our map -- we have traced the pattern of vegetation from aerial photographs and gone out in the field to determine what was there. There have been several versions made to keep pace with changes: 1972, 1986, 1992, 2000, 2005 and 2008. The colour version was created especially for the web site.
We also all have our own study trees -- a single, unique tree deep in the forest that is our own
All of the observations on which our studies are based, are recorded in our Nature Journal, a group effort that we keep updated and indexed.
