The Autumn Woods is the first and most colorful biome added by ExtrabiomesXL. The biome is mostly flat, with a few hills of varying height, and is filled with Vermillion Autumn Trees, Umber Autumn Trees, Golden Rod Autumn Trees and Citrine Autumn Trees. Oak and Japanese Maple Trees also spawn, but less frequently. Along with Chickens, Cows and Sheep, Wolves spawn in this biome. The biome is well suited to mushrooms, as both vanilla Mushrooms and Toad Stools are common, along with Autumn Shrubs, some types of grass and a few other flowers.
