Just beautiful photographs

Help me improve this site.

Please help me improve this site. There are more ways to do that:
1. Please rapport errors to me, from spelling erors to errors in determination, links and so on.
2. Here is a page with photo's of unknown /uncertainly-determined trees. If you know what they are, please let me know.
3. Please send me good links.
Thanks a lot! Hans-Cees
