Temperate Forests

Temperate Forests : 

Temperate Forests What is a temperate forest? - “Four-Season Forests” - Four distinct seasons with well-defined winters - Moderate climate - High precipitation - Includes 3-4 distinct tree species per square kilometer - Wide variety of animal life

Location : 

Location Temperate forests occur between approximately 25° and 50° latitude in both hemispheres Countries: - United States - China - Germany

Topographic Features : 

Topographic Features Soil: - Very fertile with nutrients from decaying leaves - 3 Layers: canopy, understory, forest floor Temperature: - Temperatures range from hot in the summer with highs of 86º F, to extremely cold in the winter with lows of -22 F. Precipitation: - Temperate forests receive between 20-60 inches of precipitation annually, usually in the form of rain and snow.

Flora : 

Flora Trees; three main groups - Deciduous: lose their leaves in winter; Ex: maples, oaks, chestnuts - Coniferous: have needles for leaves, “evergreens”; Ex: Pines, firs, cedars - Broad-leaved evergreens: have flat, leathery, waxy leaves, which helps keep them from losing too much water in winter when the air is dry Shrubs: - Azaleas, Laurel, Huckleberries Mosses Some plants go dormant

Fauna : 

Fauna Carnivores: - Black bears, mountain lions, bobcats, wolves, eagles, snakes Herbivores: - Squirrels, rabbits, koala bears, skunks, deer, elk, humming birds, raccoons, Omnivores: - Owls, boars, wombats, fish Some animals hibernate Burrow underground Migrate

Resources : 

Resources Timber Rich soil Rubber Maple Syrup Chestnuts

Importance & Ecological Challenges : 

Importance & Ecological Challenges Temperate forests provide habitats to a great number of diverse organisms. Temperate forests forests have a global climate-buffering capacity, so their destruction may cause large-scale changes in global climate. Logging, or over-forestation. Acid Rain Fossil fuel pollution Endangered species (The Northern Spotted owl; possible extinction)
