These are the exact coded features regarding vegetation in versions 28.2 and 29.6 for the Ithilien main biome (only differences are shown):

28.2
addBiomeVariantSet(LOTRBiomeVariant.SET_FOREST); addBiomeVariant(LOTRBiomeVariant.DENSEFOREST_LEBETHRON);

this.decorator.treesPerChunk = 6; this.decorator.grassPerChunk = 12;

this.decorator.addTree(LOTRTreeType.OAK_TALL, 500); this.decorator.addTree(LOTRTreeType.LEBETHRON, 200); this.decorator.addTree(LOTRTreeType.CEDAR, 300);

29.6
this.variantChance = 0.7F; addBiomeVariantSet(LOTRBiomeVariant.SET_NORMAL_OAK_NOSTEPPE); addBiomeVariant(LOTRBiomeVariant.FOREST_LIGHT, 4.0F); addBiomeVariant(LOTRBiomeVariant.FOREST, 2.0F); addBiomeVariant(LOTRBiomeVariant.SHRUBLAND_OAK, 4.0F); addBiomeVariant(LOTRBiomeVariant.SCRUBLAND, 3.0F); addBiomeVariant(LOTRBiomeVariant.DENSEFOREST_LEBETHRON); addBiomeVariant(LOTRBiomeVariant.FOREST_BEECH, 0.5F); addBiomeVariant(LOTRBiomeVariant.FOREST_BIRCH, 0.5F); addBiomeVariant(LOTRBiomeVariant.ORCHARD_APPLE_PEAR, 0.2F); addBiomeVariant(LOTRBiomeVariant.ORCHARD_PLUM, 0.2F); addBiomeVariant(LOTRBiomeVariant.ORCHARD_OLIVE, 0.1F);

this.decorator.treesPerChunk = 0; this.decorator.grassPerChunk = 10;

this.decorator.addTree(LOTRTreeType.OAK, 500); this.decorator.addTree(LOTRTreeType.OAK_TALL, 100); this.decorator.addTree(LOTRTreeType.LEBETHRON, 100); this.decorator.addTree(LOTRTreeType.CEDAR, 200); this.decorator.addTree(LOTRTreeType.PINE, 100); this.decorator.addTree(LOTRTreeType.CYPRESS, 100); this.decorator.addTree(LOTRTreeType.CYPRESS_LARGE, 10); this.decorator.addTree(LOTRTreeType.OLIVE_LARGE, 5); this.decorator.addTree(LOTRTreeType.ALMOND, 15);

Overall
I think Mevans served us a pretty well rebalanced tree-rich Ithilien with all these new biome variants and trees he added with. Yes, there now is a chance that non-forested landscapes generate, but that chance is fairly low if you compare it with other biomes.
