Slide 2:What is a Deciduous Forest?

A deciduous forest is a cool rainy area The trees lose their leaves in fall & re-grow them in Spring Known for color changing leaves Has 4 distinct seasons

Slide 3:Environmental Conditions

The Average temperature is 75 degrees although it can get up to 86 degrees Most of this forest is in NE America 2-5 ft. of precipitation a year Humidity is 60%-80% 6 month growing period Subtropical climate

Slide 4:Environment (cont.)

Warm summers Fairly short winters Rainfall every month of the year Trees change color w/ season Winds blow west-east 30 diff. types of trees. Very rich soil Leaves fall in fall & decay quickly in spring Daylight decreases in fall 3/4 of these forests are in North America

Slide 5:Animals in the Forest

Ant Beaver Black & brown bear Deer Dhole Fox Earthworm Frog Ocelot Muskrat Newt Rabbit Raccoon

Slide 6:More Animals

Oppossum Porcupine Squirrel Turkey Weasel White tailed deer Skunk

Slide 7:Birds of the Forest

Bala Eagle Cardinal Red-tailed Hawk Mallard duck Ruffed Goose Turkey Cuckoo Wren The robin Spotted Woodpecker Woodcock Woodpigeon Tawny Owl Buzzard

Slide 8:Adaptations

Night Vision Claws Long, sharp teeth Long tail Strong, pointy beak Stiff tail Color Long ears

Slide 9:Biotic Substances

Animals Carnivores- ex.Ocelot Herbivores- ex. Deer Omnivores- ex. Bear Decomposers- ex. Bear

Slide 10:Biotic Substances

Plants- producers- ex. fern ex. Tree ex. Flower ex. Vine

Slide 11:Abiotic Substances

Sun- Gives light for PHOTOSYNTHESIS Water- Animals drink it and cool off in it Habitat Replenished by PRECIPITATION

Slide 12:Abiotic Substances

Soil- Habitat Everything grows on it Air- We breathe it. It is recycled in PHOTOSYNTHESIS

Slide 13:Human Intervention

The graph at right shows the number of carnivores on one deciduous forest after human intervention People thought that carnivores were killing too many animals and started killing them

Slide 14:Some Endangered Species

Panda Ocelot Timber wolf Black Bear Other bear species Eagle

Slide 15:Five Layers

Tree Stratum- 60-100 ft. high, dominated regionally by combinations of trees Sapling layer- Smaller trees or younger species of taller trees Shrub layer- members of the heath family Herb layer- bloom in early spring Ground layer- layer of lichens, club mosses, and true mosses

Slide 16:Trees

Oak Maple Chestnut Beech Hickory Elm Walnut Sweet gum Basswood

Slide 17:Food Chain

Slide 18:The Ocelot

A medium sized slim cat 1 litter 0f 2-4 born after a gestation of 70 days Climbs well and silently Main food is small animals and birds. Ocelot population has declined because of deforestation and human intervention

Slide 19:Predators and Prey

The rabbit will eat the grass The ocelot will eat the rabbit The ocelot will die Worms and mushrooms will eat the ocelot

Slide 22:Conclusion

Although the deciduous forests are shrinking because of deforestation etc. these forests are still a place of abundant life, beauty, and animals.
