Temperate Deciduous Forests By Marli Milano
CLIMATE • The annual temperature ranges from -50 to 50˚C • ± 50 cm of precipitation annually, up to 200 cm in colder areas • Summer and winter are distinct seasons
Broadleaf trees Oak, maple, beech, hickory, chestnut, magnolia, birch, linden, sweet-gum, walnut, elm, sycamore, ash Also spruce, fir, pine trees Perennial herbs Mosses, lichens, shrubs wildflowers, ferns, mushrooms, FLORA
Insects, spiders, slugs, frogs, snakes, turtles, salamanders Birds: broad-winged hawks; snowy, screech, horned owls; various woodpeckers; hummingbirds; chickadees; wild turkeys; bald, eagles; etc. Mammals: opossum, white-tailed deer, raccoons, red foxes, coyotes, porcupines, gray and red squirrel, chipmunk, skunk, black bear, mice, weasels, platypus FAUNA
Instrumental Values to Humans Temperate deciduous forests have many uses for humans including: wood for building, land for agriculture and stone for mining (once trees are eliminated), places to live, and animals to hunt. Mining in Germany where there was once a deciduous forest
Threats to Deciduous Forest Biomes • Industrial air pollutants • Acid rain • Disease and pests • Clear cut logging • Clearing land for agriculture • Mining • Global warming • Introduction of invasive species • Human occupation
Clear Cut Logging & Deforestation Clear cut logging and deforestation are a locus of concern for deciduous forests because these forests are habitat to a wide variety of animal and plant species. Clear cut logging takes away the trees in which many animals make their homes, making endangerment more likely, and it takes away the biodiversity in types of trees. Deforestation, as well, takes away habitats from plants and animals to make room for houses and industry.
Limiting Factors Limiting factors of the temperate deciduous forest biome include: rainfall, outward industrial expansion, deforestation etc.
