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.
