Biomes: the lands and seas.

How a biome is chosen

The planet's climate is worked out from its temperature and humidity, its height above the sea and how near it lies to the coast. Cold ground becomes frozen tundra, dry hot ground becomes desert, and wet hot ground becomes jungle. Very high ground becomes peaks, the shores become beaches, and volcanic ground becomes barrens. Under the sea the depth decides what you find: shallows and reefs near the surface, open blue water further out and the trench at the bottom.

Land biomes

Biome	What it is like	Trees and plants	Ground warmth (C)
Sunmead	Temperate meadow, the common gentle land. Good for a first base.	Broadleaf and birch trees, grass and bright flowers.	16
Pinecrest Highlands	Conifer hills, cool and snowy on the high ground.	Needle pines, with rocks and violet flowers.	6
Brightsand Expanse	Sun-baked desert of pale sand. Dust blows often.	Sparse sunspine spires and a few palms.	38
Rustmesa	Ochre badlands of flat-topped rock, banded in colour.	Dead snag trees and very little grass. Many boulders.	30
Emberwood	Crimson woodland, with trees the colour of old blood.	Crimson bloodwood trees and dense moss.	14
Hoarfrost Flats	Frozen tundra of snow and permafrost. Hard going.	Thin spruce, very few plants.	-18
Mirefen	Marsh, soft and wet, with pools and reeds.	Willow trees and reeds.	18
Verdance Tangle	Tropical jungle, thick and humid.	Tall jungle trees and palms. Dense undergrowth.	30
Ashfall Barrens	Volcanic ash ground, with lava pools near the surface in places.	Dead snag trees. Many boulders.	42
Skyreach Peaks	High mountains. The tops are white with snow above about 175 blocks.	Sparse conifers and a lot of bare stone.	-4
Saltstrand	Sandy beaches along the coast.	A few palms and seaside grass.	22

Caves

Glowcap Hollows are glowing caves underground. The floors are covered in luminous mycelium, with glowcap mushrooms and purple grass. No trees grow here, and the light comes from the caves themselves.

Sea biomes

Biome	Where it is	What it is like
Tidewash Shallows	Shallow water near the shore	Sandy floor with a little grass. The common shallows.
Coralreach	Warm shallow water, near the surface	A coral reef with rose, amber and teal coral. Seagrass grows here.
Kelpwood Deep	Cold water a little deeper down	A kelp forest on a gravel and stone floor.
Wide Blue	Open water, more than 55 blocks deep	Deep open sea over basalt.
Hadal Rift	The deepest trench, more than 150 blocks down	Dark, cold water over basalt. The Kraken sleeps here. See The Kraken.

The moons

The two moons of home are not planets you can grow in. The Rust Moon has iron-red dust plains, and the Pale Moon is a dead grey world of regolith and craters. Neither has air, weather or living things.

Warmth and the day

The warmth shown in the table is the ground's usual warmth at the surface. It moves a few degrees either way with the time of day, warmer at noon and cooler at night. Rain, storms and snow cool the air further (see Weather, seasons and the day). Up high the air gets colder, and deep underground the rock sets the heat instead (see Layers of the planet).

Tips

• Sunmead, Emberwood and Verdance are the easiest places to find wood and food.
• Boulders are commonest in Skyreach, Ashfall and Rustmesa, which is where you go for stone.
• Brightsand and Ashfall are very hot. Carry water and watch your heat on the Strata Gauge.
• Hoarfrost and the peaks are cold. Dress for it, and build somewhere out of the wind.
