Terrestrial Biomes - Land Terrestrial biomes are distinguished primarily by their predominant vegetation, and are mainly determined by temperature and rainfall (climate).
1. Tundra A treeless biome with a layer of permafrost beneath the surface. Cold and dark much of the year Temps: -60 - 50˚F Precipitation: 6 - 10”/year (mostly snow)
2. Boreal forest aka taiga Evergreen forest Long cold winters Temps: -65 - 70˚F Precipitation: 12-33”/year (mostly snow)
3. Temperate (deciduous) forest Has four distinct seasons and loses its leaves in the fall Temps: -22 - 86˚F Precipitation: 30 - 60”/year
4. Temperate woodland and shrubland Areas where open woodland is mixed with shrubs. If shrubs are dominant, it is called chaparral. Temps: 50 - 104˚F Precipitation: 15 - 40”/year
5. Temperate grassland Very fertile soils mean that this biome is covered in thick grasses. Fires, drought and animals keep it from becoming a forest. Temps: -40 - 100˚F Precipitation: 20 - 35”/year
6. Desert Extremely dry Temps: 0 - 120˚F Precipitation: 1 - 10”/year
7. Tropical savanna Grasses and scattered trees Hot rainy summers; cool, dry winters Temps: 68 - 86˚F Precipitation: 20 - 51”/year
8.Tropical seasonal forest Forest that loses nearly all of its leaves in the dry season Temps: 68 - 77˚F Precipitation: >78”/year
9. Tropical rain forest Warm temperatures and large amounts of rain year round Temps: 75 - 80˚F Precipitation: 78 - 393”/year
