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.

• Coastal Strand
• Deserts
• Dry woodlands
• Subalpine grassland/shrubland
• Tropical rainforest
• Alpine deserts
• Mesic forests

• Hawaiis biomes are classified based on its
• elevation
• moisture regime
• dominant life forms
• vegetation structure

10

• Hawaiis five elevation zones
• Coastal 0-30 m
• Lowland 30-1000 m
• Montane 1000-2000 m
• Subalpine 2000-3000 m
• Alpine gt 3000 m

11
Moisture Classification For each elevation zone,
three general moisture categories are
recognized  

• Dry - lt 120 cm/yr (47in)
• Mesic - 121-249 cm/yr (46-97 in)
• Wet - gt 250 cm/yr (98in)

12
Vegetative Structures

• Forest dense canopy has 60-100 coverage
• Woodland is more open, with 10-60 canopy
• Shrubland are distinguished by shrubs gt 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
