Biomes

In Project Rebearth, the world is divided into four biomes that determine which resources are available, how much buildings cost to construct, and how efficiently settlements can grow. Biomes are derived from real-world climate data based on the WWF terrestrial ecoregions, mapped onto a full 1:1 replica of Earth. Where a player builds directly affects production rates, construction costs, and housing upkeep.

Each biome contains multiple climate zones representing more specific ecological regions. The climate zones also influence the vegetation visible on the surface.

Overview

Biome	Construction Material	Resource Focus	Description
Wood Biome	Wood	Wood production	Forested regions — tropical, temperate, and subtropical
Stone Biome	Stone	Stone and Ore production	Mountainous, boreal, and tundra regions
Earth Biome	Earth	Earth and Glass production	Arid, grassland, and Mediterranean regions
Arctic Biome	Wood (2× cost)	No raw resource extraction	Extreme polar regions

All resources can be found in every biome through trade and expeditions, but the efficiency of local production varies significantly depending on the biome. No single biome is fully self-sufficient; successful players specialize based on their environment and rely on trade and global cooperation to access missing resources.

Construction

In the Wood, Stone, and Earth biomes, buildings cost the biome's primary resource ( Wood, Stone, or Earth respectively). In the Arctic Biome, buildings cost Wood at double the normal amount.

Housing Upkeep

All housing buildings consume Wood and Food daily. Food consumption is identical across all biomes for a given housing tier. Wood consumption, however, varies dramatically: the Earth Biome reduces Wood upkeep to roughly one-tenth of normal, while the Arctic Biome doubles it.

Resource Production

Each biome has distinct production strengths:

• The Wood Biome produces the most Wood from Woodcutters and has balanced yields from other extraction buildings.
• The Stone Biome has the highest Stone output from Stone Cranes and the highest Ore yield from the Iron Mine.
• The Earth Biome has the highest Earth output from Clay Cranes and Claypits, making it ideal for Glass production chains via the Glassworks.
• The Arctic Biome has no access to raw resource extraction buildings (Woodcutter, Quarry, Claypit, Iron Mine, Foraging Hut, Glassworks, and Fields are all unavailable). Food processing buildings such as the Fishery, Windmill, Bakery, Creamery, and Brewery still operate normally.
