Woodlands
Woodlands will provide everything needed for starting a new game, especially Wood, Moss, Red Mushrooms, Vines, Flowers and Beeswax, also every kind of material needed to build a Nasic House, including Cragwood Logs that can be found lying on the ground.

Jungle
You can recognize Jungle-biomes by their tall Wildwood trees adorned or even covered by many Vines. Be careful when advancing, because jungles are home to aggressive red Feral Pigsies that can spawn on blocks of Detritus during the day.

Swampland
The floor of Swamplands is usually made of common green Grass adorned with Tallgrass and Red Mushrooms, but more importantly, there are also at least small ponds up to large swamps made of green (non-poisonous) Bog Water with a bed of Mud with Reeds, Cattailss and Lily Pads inside.

Mountains
Mountains are a good source of Coal and Obsidian, as you can sometimes see Nodes embedded in stone visibly on the surface/sides of Mountains. More Nodes can easily be found by digging into the Mountains (a Excavator might be of help with that).
