This document summarizes the plants and animals that live in deciduous forests. It describes how trees like oak, hornbeam, and beech are the most common types of deciduous trees and how they provide habitat for animals in the tree canopy layer. The understory layer is home to shrubs like hazel and hawthorn, which support insects and birds. The forest floor layer contains fungi, mosses, ferns and small animals like snakes, toads, mice and hedgehogs. All the layers are interconnected through food chains.
