I've come across a lot of things on my projects in the last 4 or so years but for the first time today, I've come across bird flu.  A nasty strain appartently.
So far I've come accross: loads of great crested newts (and badgers which rip newt fencing), japaneese knotweed, endangered species - voles and all sorts, listed trees, hogsweed, cow parsley, endangered and protected flowers, the list goes on.
Only a dead body to go, and I think I may have come across nearley everything possible.  I think my projects are cursed  :lol:
