The temperate rainforest is a biome of cool but rainy weather which promotes the growth of enormous trees.
Mild and wet
Rainfall: at 200 cm/yr (rain or snow)
Temperature: Between 5-20°C
Northwest coast of North America, southern Chile, New Zealand, portions of southeast Australia

Evergreen coniferous trees (Redwoods, Douglas fir, Sitka spruce, Hemlock)
Understory of deciduous trees
Mosses and lichens abundant
