Jennifer pd.6-Neyland/Butler 5/3/01 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 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 Environment (cont.) • Warm summers • Very rich soil • Fairly short winters • Leaves fall in fall & • Rainfall every month decay quickly in of the year spring • Trees change color • Daylight decreases w/ season in fall • Winds blow west- • 3/4 of these east forests are in • 30 diff. types of North America trees. Animals in the Forest • Ant • Frog • Beaver • Ocelot • Black & brown bear • Muskrat • Deer • Newt • Dhole • Rabbit • Fox • Raccoon • Earthworm More Animals • Oppossum • Porcupine • Squirrel • Turkey • Weasel • White tailed deer • Skunk Birds of the Forest Bala Eagle Red-tailed Hawk Cardinal The robin Ruffed Goose Mallard duck Woodcock Turkey Cuckoo Wren Tawny Owl Spotted Woodpecker Woodpigeon Buzzard Adaptations Claws Night Vision Long, sharp teeth Long ears Long tail Strong, pointy beak Stiff tail Color Biotic Substances • Animals – Carnivores- ex.Ocelot – Herbivores- ex. Deer – Omnivores- ex. Bear – Decomposers- ex. Bear Biotic Substances • Plants- – producers- ex. fern – ex. Tree – ex. Flower – ex. Vine Abiotic Substances • Sun- – Gives light for PHOTOSYNTHESIS • Water- – Animals drink it and cool off in it – Habitat – Replenished by PRECIPITATION Abiotic Substances • Soil- – Habitat – Everything grows on it • Air- – We breathe it. – It is recycled in PHOTOSYNTHESIS Human Intervention • The graph at right 50,000 shows the number of 45,000 40,000 carnivores on one 35,000 deciduous forest 30,000 25,000 after human 20,000 Before 15,000 intervention After 10,000 • People thought that 5,000 0 carnivores were killing Carnivores in the too many animals and forest started killing them Some Endangered Species Panda Timber wolf Eagle Other bear species Ocelot Black Bear 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 Trees Chestnut Oak Elm Maple Beech Hickory Sweet gum Basswood Walnut Food Chain Grass Producer Bear Deer Ocelot Omnivore herbivore Carnivore Mushroom Decomposer 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 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 My Sources Were • “Ocelot.”www.enature.com • “Temperate Broadleaf Deciduous Forest Animal Printouts.” www.enchantedlearning.com • Allaby, Michael.Biomes of the World.
