When we went to RSC, what they showed us to create this was a rectangle that that populated at low density: the density of assets in the decal is configurable from 'very sparse' to 'overcrowded, virtually Amazon jungle'. Then you overlay another decal on top, also at low density, with another tree variety, and hey presto - a forest with multiple tree species.
As a further variation, you can choose for each decal to stretch or compress the asset height - say, vary it by 10% - so that some trees are 10% taller, and some 10% shorter. It was very effective.
