It is odd. I honestly just don't build in the Black Forest, later biomes are actually "safer" because they don't have the random greydwarf spawn problem. I'd actually recommend campfires over workbenches, make sure the outer "ring" of fires stay lit, that way even if something does spawn and wander over it will be deterred by the fire instead of just deciding to attack your workbenches.
