[Yes, every non-human organism is pretty much hunted, even the dwarf kingdom (but it is protected by the wild dragons living in its mountains--they are a class B but are hard too fight on mountains).
We don't hear about it much right now because we haven't met many characters over 500 years old.
Though I warn that this stuff is from the WN, I know the LN changes some details, but the foundation is pretty much the same.]
