Due to the order things get spawned in different mapgens, I often find things growing where there isn't enough light. So I added this hack to woodsoils/nodes.lua - it is far from perfect, it messes up the subtleties around ferns and results in little growth under oak trees. I may modify it to differentiate between conifers and deciduous trees, but for now it has the right sort of effect. Currently it kills off anything in group:flora, which may leave wild veg from farming* untouched.
