05 Biome Lab
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.

Hawaii’s biomes are classified based on its: elevation moisture regime dominant life forms vegetation structure
Hawaii’s five elevation zones: Coastal 0-30 m Lowland m Montane m Subalpine m Alpine > 3000 m
Moisture Classification For each elevation zone, three general moisture categories are recognized: Dry - < 120 cm/yr (47in) Mesic cm/yr (46-97 in) Wet - > 250 cm/yr (98in)
Vegetative Structures Forest dense canopy has % 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
