I generally feel with Bulletpoint concerning the pine trees. Currently we can only "improve" by use of adding bocage and bushes to the forest interiors (see Kaunitz "improvement suggestions" thread), as well as adding bumps to the terrrain mesh to increases density and cutting LOS/LOF. Modding also helps by making bocage look like parts of pine trees. Examples below show crushed and fallen trees in a pine forest by adding bocage objects, as well as other stuff from the flavor objects collection.
