I agree that trees likely have little impact at HF. Some trees may react
differently others and it may also vary with the seasons. This is not
something that can be easily noticed. Since we have to work with what we
have I would not be concerned about the trees, unless one or two are
physically in the way of the antennas.

I don't think you will see much impact on HF, but the foliage losses can
become a factor as you up into VHF, UHF, and beyond. Also, at HF, you're
rarely trying to pull signals out of the noise floor.
At my QTH my tower (around 70') was once out in the open, but all the
trees have grown up around it and it is largely sheltered by trees within
about 30-50'. On HF I don't notice much transmit/receive difference at
all, but the tower and antennas are well hidden! In addition, the
surrounding trees provide a wind break so the structure is not getting the
high winds full-blast.
