Key Concept
Temperate Rain Forest Biomes
What are Land Biomes?
Regions of Earth between the tropics and the polar
circles are temperate regions. In what ways do humans affect temperate rain
forest?
Temperate regions have mild climates with distinct
seasons.

Temperate rain forests are moist ecosystems in
coastal areas with rich, moist soil.

SUMMARY
What are Land Biomes?

Earth has seven major land biomes, ranging
from hot, dry deserts to cold, forested taigas.
Forests are dominated by spruce, cedar, and
redwood trees.
Half of Earth’s species live in rain forest
Fungi and small flowering plants grow on the moist biomes.
forest floor.

Animals include mosquitoes, owls, deer, and bears.

Logging can destroy the habitat of forest species,
but rich soil enables cut forests to grow back.
