Temperate forests have warm summers and cold winters, receive a lot of rainfall, and typically support a wide variety of deciduous trees. The understory is rather dense with saplings and shrubs. A wide variety of temperate forests meet this description: Some ecologists recognize up to four different types of temperate forests that differ primarily in the proportion of broad-leaf deciduous trees (e.g., oak, maple, beech, birch, and hickory), coniferous trees (e.g., lodgepole and jack pines) and broad-leaf evergreens (e.g., holly, rhododendron, and laurel) that they contain.
Deciduous forests support herbivorous (or omnivorous) deer, bears, wild boars, badgers, squirrels and other rodents. The main predators are wolves, foxes, cats, and owls.
