Gathering resources

[Applesauce]

I was wondering if a timer could be placed on resources that we gather.
It takes time before a rock is ready to be mined again.
It takes time before a tree can be cut again, and then more time before it bears fruit.
An example of time for different steps in what it offers.

Sometimes resources release a monster ( maybe even could be another penalty like the Blood Fairy in Cadomyr, temporary blindness or such)
Sometimes they release a bonus ( gems, elements or lesser items )

My question is... Could a timer be placed on these resources?
The more used it is, the more it may release a negative "Bonus"

The tree right outside the gates gets cut often. So maybe the Trolls guard it more. The rock at the back of the most remote mine, may be more likely to have an element of earth in it.

If it could be done, I think it should be a slow process. Maybe one percent chance a week for both (increasing/ decreasing) to a total of maybe 20%. But it would increase the motivation to hunt out that lone resource, instead of always the one that is closest.
