Transcript of Temperate Deciduous Forest

Temperate Deciduous Forest By Gary Liu, Phillip Tran
Sarah Chen, Michelle He General Characteristics Other Pollution Runoff Testable Question Environmental Value Unique Features Seasons Economic Value Predominant Plant Species Species Adaptation Where is the Temperate Deciduous
Forest? Oaks in North America
Hickory, Chestnuts, Maples, Beech and Sycamores.

NPP-5,000 kilocalories/meters squared/year Heavily logged-many different types of trees; many of the hardwoods have high economic value for their wood

Converted for agricultural use and for grazing; the value of the trees allows for the establishment of industries that could benefit the region

Additionally, the forest provides plants for herbs and medicines for the medical field Deciduous trees drop their leaves in the fall, deciduous forests go through all four seasons every year, leaves change color in the fall, drop in the winter and grow back in the spring Summer-long days and warmer temperatures cause an increase in productivity.
Fall-trees pull back what nutrients they can, and put waste into the leaves, which fall off.
Winter-temperatures may be at or even slightly above freezing, and many organisms will decompose the fallen leaves and return the minerals to the trees.
Spring- plants on the forest floor and smaller trees leaf before the larger trees. Many plants on the forest floor flower. Many different species of animals live in the temperate deciduous forest, so it represents a habitat that houses a unique blend of organisms
There are also many different species of trees in this type of forest, with a very rich diversity that is protected by governments around the world There are heavier human populations in temperate deciduous forests, so these areas are also more heavily polluted. (Nitrogen, ozone, sulfur dioxide)

Because of pollution, there is heavier acid rain. There is a large portion of the human population that live in areas that once supported temperate deciduous forests. The biggest threats to the forest are development and agriculture. Because many trees are cut down to allow for urban development, this increases erosion and can cause excess runoff. Eutrophication can happen, affecting areas other than the forests. Logging is also a detriment to the temperate deciduous forest, with many of the trees in the forests being cut down and not being able to grow back. How does human population density affect the species
richness in a Temperate deciduous forest?
Hypothesis: these two variables will have an inverse
relationship North America, in western Europe, in China, Korea, Japan and Australia Some animal species such as chipmunks and squirrels will store food to last through the winter

Black bears’ fur will thicken as it gets colder

Many of the birds will migrate south to Central or South America during the winter Average temperature: 50 degrees F, hot summers, cold winters
Rainfall: 30-60 inches a year
Soil quality: VERY FERTILE because of leaf decay from fallen leaves Works Cited

Temperate deciduous forests are located in the mid-latitude areas which means that they are found between the polar regions and the tropics.

The temperate deciduous forest occupies much of the middle of the Whittaker diagram, and to those of us who live here, it sure feels that way.

Forests are the normal ecosystems in regions with year-round rainfall that is adequate to sustain tree growth. Forests are also the most productive systems the land can support, and they are self-sustaining. Temperate Deciduous Forest
