A2 - Global Forest Overview

1) Describe the key characteristics of temperate forests

higher latitudes, distinct winters, 4-6 month frost free growing, precipitation peaks in summer

2) Describe the key characteristics of tropical forests

lower latitudes, no frost cycle, mean temp of > 18 C, two seasons: rain or no rain

3) Describe the key characteristics of boreal forests

long cold winters, short growing seasons- less than 3 months, -40 to -45 C freezing temperatures.

* Geographic distribution of abiotic factors affects the distribution of forests.

biotic factors = living factors

4) What factors vary on a mountain range?
