Accipter,

you want to know why Demeter (and Gaia before Her), have not included
the
lowly blueberry in the care of Oakstone. The reason for that is so
simple, you don't even need to be smart to figure it:
The reason the blueberry is not subject to Oakstone overharvesting
limits
is, that the blueberry does not suffer from harvesting down to 0, unlike
every other plant in Achaea, which does suffer from overharvesting.

The humble blueberry gives us its fruits, takes a nap, and a year later,
it wakes up and grows full of fruit again. No other plant manages that,
if you harvest them down they die.

Hope this helps,
Mazur Windsong.
