  1. Biome Lab 05

  2. BIOME • A biome is a large geographical area of distinctive plant and animal groups, which are adapted to that particular environment. • The climate and geography of a region determines what type of biome can exist in that region.

  3. Biomes of the World tundra chaparral deciduous forest alpine taiga desert scrub savannah grassland desert rainforest

  4. Environmental Diversity Extremely wide range of habitats temperature moisture soils vegetation

  5. Environmental Diversity Cold & Dry Cool & Dry inversion trades Warm & Dry Warm & Wet Warm & Very Dry Hot & Very Dry Hot & Wet

  6. Hawaii's Primary Terrestrial Biomes • Coastal Strand • Deserts • Dry woodlands • Subalpine grassland/shrubland • Tropical rainforest • Alpine deserts • Mesic forests

  7. Factors determining Biome formation in Hawaii • Climate • Substrate • Elevation tradewinds Ko’olau

  8. Hawaii’s biomes are classified based on its: • elevation • moisture regime • dominant life forms • vegetation structure

  9. Hawaii’s five elevation zones: • Coastal 0-30 m • Lowland 30-1000 m • Montane 1000-2000 m • Subalpine 2000-3000 m • Alpine > 3000 m

  10. Moisture Classification For each elevation zone, three general moisture categories are recognized: • Dry - < 120 cm/yr (47in) • Mesic - 121-249 cm/yr (46-97 in) • Wet - > 250 cm/yr (98in) Barking Sands, Kauai Big Island Crater of Mt. Waialeale

  11. Average Rainfall, Oahu

  12. Vegetative Structures • Forestdense canopy has 60-100% coverage • Woodland is more open, with 10-60% canopy • Shrubland are distinguished by shrubs > 1m high • Dwarf shrublands have a canopy height of 1 m or less • Herblands are composed of small, nonwoody plants • Deserts receive less than 25 cm/yr of precipitation and are sparsely vegetated

  13. Answer questions Activity 1: General description of Oahu Activity 2: Precipitation on Oahu Activity 3: Ecological systems Due next week
