Temperate Deciduous Forests
Transcript of Temperate Deciduous Forests
. Climate: Temperate deciduous forests see
extreme seasons with hot summers getting
up to about 30 degrees Celsius, extremely cold winters with temperatures averaging about 0 degrees Celsius, and large amounts of precipitation throughout the year.
A temperate deciduous forest that has matured has distinct vertical layers, usually with a closed canopy, under-story trees, a shrub layer, and an herbaceous layer. Most of the trees in northern
hemisphere temperate deciduous forests lose their
leaves and become dormant in the winter.
In northern hemisphere temperate deciduous
forests, many mammals hibernate during the winter
while many bird species migrate south. What are Temperate Deciduous Forests Most known for?? By Michael Mulady and Trevor Chapman Native Species (Plants) 1.American Beech
2. Carpet Moss
3. Common Lime
Species: x europaea
4. Guelder Rose
Species: illinoensis Native Species (Animals) 1.American Bald Eagle
2. American Black Bear
4. Duckbill Platypus
5. Fat Dormouse
Species: glis Features: The word "deciduous" means exactly what the leaves on these trees do: change color in autumn, fall off in the winter, and grow back again in the spring.
Animal: The Temperate deciduous forest is most known for the American Black Bear (Ursus Americanus).
Plant: White Oak (Quercus alba ) Predator-Prey Relationships In temperate deciduous forests, a wide range of predator-prey relationships are seen. As seen in this food web, they occur most commonly between:
Cougars, which ambush or outrun deer
Brown bears, which will usually stalk and ambush deer, but are also omnivorous and feed on vegetation
Foxes, which use their agility to hunt small animals like rodents and small birds
Owls, which ambush rodents and other birds
Skunks, which feed on insects and use their anal scent glands as a defensive weapon against potential predators
Birds, which also feed on insects
Opossum and fishers, which opportunistically feed on a wide variety of small animals such as insects, frogs, birds, snakes, small mammals, slugs, and earthworms. As a defensive technique, opossum will also "play possum," mimicking a dead or sick animal. Both opossum and fishers will hiss at their target if they feel threatened. Today, less than a quarter of pre-industrial revolution temperate deciduous forests remain on Earth. It comes as no surprise that humans are responsible. This is caused by:
Human population growth, which leads to development. Since the land occupied by temperate deciduous forests are not too warm, yet still cooler than their tropical counterparts, which have high mosquito populations, it makes an ideal location for cities and suburban areas.
Increased agriculture, which is due to the rich soil of temperate deciduous forests that is easily plowed.
Logging; most trees in temperate deciduous forests are hardwoods and are slow-growing. This puts them in higher demand, being ideal for construction, and makes them more difficult to replace.
Acid rain from coal burning also threatens both the plants and the wildlife of temperate deciduous forests.
Global warming, due to its affects on rainfall patterns, has a significant affect on the water cycle in temperate deciduous forests. Why Temperate Deciduous Forests Are Disappearing THE END Invasive Species 1. Multiflora Rose- Rosa Multiflora
This plant was introduced from England to be used as a natural fence for livestock. It reproduces quickly, therefore it is known as an invasive plant to the temperate deciduous forests. 2. Scientific name: Anoplophora chinenis (Forster)
Common name: Citrus long horned beetle
Introduced to U.s Temperate deciduous forests from China, Japan and Korea. Harmful to many hardwood trees such as the pecan tree.
