Hi, 
here again your forest areas overlap with reads and ponds.

Could you please draw the areas in a way that they stop at the edge of a road/highway. Also if there are other non-forested areas inside the forest (e.g. ponds, swamps,..) please create a multipolygon instead and add those areas as 'inner' member.
