No forests exist in deserts, just a few trees in places where their roots can get at some underground water.
The three major forest biomes are coniferous forests, deciduous forests, and tropical rain forests.
The weather during the winter is cold, but when snow melts in the spring, some parts of the forest become swamps.
There are not many different types of trees in coniferous forests because of the cold weather, and the poor soil.
Less water evaporates from their leaves because of the shape of their needles.
