Deciduous Forests

Deciduous forests are found in the US, Europe, Russia, and China. These forests adapt to seasonal changes by shedding leaves, enriching the soil with decayed vegetation. Spring brings growth due to moderate temperatures and rainfall. Various trees, like birch and chestnut, thrive, supporting diverse animal life. However, many forests have been cleared for agriculture, though some remain extensive in eastern America.
