Research on this began in 1989, quite a long time ago. So there's been a lot of awareness for a while. Most of the web pages on Niagara Escarpment nature activities already mentions this old forest (one example is here: http://brucetrail.org/pages/about-us/the-niagara-escarpment).
However, you are right to worry -- apparently in this case the worry is that this area gets a lot of rock climbers, and there does seem to be a significant concern about rock climbing's impact on the trees (and other fauna). Yes, some actions are being done to protect them too. This article goes into some of the detail.

Nitpick, but trees are flora, not fauna, so that parenthetical should probably be stated differently, perhas as either "(and other flora)" or "(and fauna)".
One of the concerns was the impact on lichen for instance; I think lichen is neither considered flora or fauna.
Though I won't deny we have some gung-ho climbers who don't care. Those guys tend to be shunned by the climbing community and are the kinds of people who have and cause accidents.

That said, I believe rock climbing is forbidden @ Rattlesnake point and surrounding area where these trees I believe are located.
