Forest Biomes

Forest Biomes. 1. Taiga = northern coniferous forest Long winters (6-10 months); average temp. below freezing Plant growth occurs in summer - constant daylight & high precipitation (~10cm/month) Plants: conifers shape of leaves & waxy coating prevent H 2 O loss

Presentation Transcript

  1. Forest Biomes 1. Taiga= northern coniferous forest • Long winters (6-10 months); average temp. below freezing • Plant growth occurs in summer - constant daylight & high precipitation (~10cm/month) • Plants: conifers • shape of leaves & waxy coating prevent H2O loss • Cone shape prevents snow build up • Pine needles makes soil acidic • Animals: summer birds; mice; hares, lynx, foxes, wolves • Also called Boreal Forest and Coniferous Forest

  2. Forest Biomes 2. Tropical Rain Forest • Near equator (South America, Africa, SE Asia, Australia) • High precipitation & moderate temps year round • Helps regulate world climate by sucking up CO2

  3. Forest Biomes • Tropical Rain Forest continued • Plants: buttress root trees, orchids, epiphytes, etc. • Animals: parrots, monkeys, snakes, tons of insects • Soil is nutrient poor b/c decomposition happens so fast & all the plants suck up nutrients Layers :

  4. Forest Biomes • Tropical Rain Forest continued • Provides food & medicines • Biodiversity fact: tropical rainforest covers <7% of Earth’s surface, but contains 50% of all plant & animal species

  5. Forest Biomes • Tropical Rain Forest continued • Threats: logging, agriculture, & oil exploration • Plants & animals face habitat loss & poaching • Largest Rain Forests occur in the Amazon Basin of South America

  6. Forest Biomes 3. Temperate Deciduous Forest • Eastern US, Europe & Asia • Abundant rainfall, moderate temp. • Trees: maple, oak, birch • Plant adaptation: trees lose leaves each fall • Animals: deer, squirrel, bears, insects, birds • Some hibernate • Threats: development, logging • Also called Temperate Broadleaf • Does this sound familiar? • It’s our biome!!!

  7. Forest Biomes • 4. Temperate Rain Forest • Pacific Northwest US, Australia (coastal areas) • High precipitation & moderate temps year round • Trees: spruce, fir, redwood • Animals: flying squirrel, bears, insects, cougars, birds – northern spotted owl • Threats: development

  8. Assignment: Forest Biomes Bubble Map Extra Credit to those that are nice enough for me to keep! • By yourself, create a bubble map for all four types of forest biomes (coloring is optional but preferred) - Due Tomorrow at end of period! • Each forest must have: • Center title • Conditions section: • Climate • Threats • Animals: • Examples & adaptations • Plants: • Examples & adaptations • Illustrations throughout
