This is a good question. I think it would be good, in general, for people to think about the impact of humans on the environment. Our footprint can do a lot of harm and has already done a lot of harm. All one needs to do is to think about things like global warming. In addition, some of the damage is irreversible. So, a policy that seeks to protect the environment or beeches in this case is a great idea.
As for closing all beeches for one day, this might be a little drastic and may have a lot of public uproar, because tourism is how Hawaii makes money. In light of this, it is possible to think of other alternatives. Perhaps there can be a system that is implemented where some beeches are closed and some are opened. This type of arrangement can be a good middle ground.
