The only time the word 'down' is used in connection with the trees is this:
HALT: ...side facing the...interesting. The indentations look like something twisted as it sat down on them. Looks like someone took something and sat it down and twisted it from side to side. Very strange.
The tape then goes on:
HALT: Looking directly overhead one can see an opening in the trees, plus some freshly broken pine branches on the ground underneath. Looks like some of ‘em came off about 15 to 20 feet up. Some small branches about an inch or less in diameter.
So where has the 'tree(s) knocked down' claim come from?
