David,

I don't think there is a list per se. Trees surely don't help but 
they don't seem to be deal breakers. I use a 90 foot vertical with 3 
x 100 foot top load wires spaced 5 feet apart. It is supported 
between two grounded towers and there are plenty of trees around. I 
don't have any trees directly under the top hat which may help. I 
think I'm doing quite well with 150 watts output. My EIRP calculates 
to 0.5 watt, not accounting for tree influence.

73,
Paul N1BUG
