1. Vegetation Regions Based on the ecosystems they support
Ecosystem = biome

2. Forestlands Categorized by the type of tree they support:
Deciduous trees: aka broadleaf trees.
Shed their leaves at least once a year
Almost exclusively in the northern hemisphere
The rainforest is covered with broadleaf trees (usually stay green all year)
Coniferous trees: aka needleleaf trees.
“cone-bearing” trees
Northern regions of North America, Asia, and Europe

3. Grasslands Mostly flat, very few trees, grassy plains
Tropical grassland, called savanna
Northern hemisphere, called steppe or prairie
Southern hemisphere, called papmas

4. Desert and Tundra
Plants in these extreme climates are specially adapted to tolerate the dry or cold conditions.
Tundra:
Plants that hug the ground: mosses, lichen
Desert: plants that can conserve water and withstand heat:
Cacti, sagebrush, shrubs
