Biome

The following table is information taken from the | Official Spreadsheet, which contains more technical data.

Bees
Bees will only work in certain climates, which varies by species & tolerances. Additionally they will only produce their specialty combs in a preferred habitat - one that matches the species listed Climate/Humidity. Increases in altitude reduces temperature, which may change the climate if it's close to a break point.

IC2 Crops
IC2 takes the highest value tag associated with a biome to determine nutrients. Nutrients cannot be lower than zero, meaning that only five tags actually influence crop growth. Higher nutrient value and humidity biomes grow crops faster. The max humidity/nutrient biomes are Bamboo Forest, Bayou, Bog, Dead Swamp, Fen, Fungi Forest, Grassland, Jungle, JungleHills, JungleEdge, Land of Lakes Marsh, Lush Swamp, Marsh, Moor, Oasis, Ominous Woods, Quagmire, Rainforest, Silkglades, Sludgepit, Tropical Rainforest, Tropics, Wetland, Swampland, Swampland M, Undergarden, Fire Swamp, Twilight Swamp, rwg_riverWet, rwg_riverOasis, rwg_oceanOasis, rwg_tropical, rwg_jungle, and rwg_oceanWet. For a more in depth calculator, see the IC2 crop growth tool.
