In this temperate zone biome, rainfall varies from 30 to 60 inches a year. Humidity may be high.
Summers are warm, but winters are cold, and there is often snow.
There are four definite seasons. This biome is home to many kinds of deciduous flowering trees. Deciduous trees need a growing season of about 120 frost-free days. In spring they draw on their reserve food to make new leaves. This takes time in the cool spring weather.
