Primary and secondary succession
By Ethan le
Primary succession
Primary succession is when new life grows on newly formed land which nothing has grown on like a volcanic rock after an eruption. It takes 1000 years to reach climax community. After the eruption lichens and mosses grow (To the right).
After lichens and mosses
After the lichens and mosses ,the nutrients of the dead plant and the soil it made is left behind. Then shrubs, herbs, and small bushes grow.
Grass
The shrubs and herbs produce soil to grow grass.
Small forest
After the grass comes in trees come in like Jack pines, Black spruces, and aspen.
Climax community
Tall trees used for buildings, paper, etc. The climax community consists of balsam fir, paper birch, and white spruce.
Secondary succession
After primary succession
There is a forest fire or tornado that clears out the land. Then Secondary succession takes it's roll. Secondary succession is when a natural disaster strikes and the plants grow off the nutrients in the ashes and soil. It takes 100 years to reach climax community. Then annual plants grow (to the right).
Grasses
After the annual plants grow then grass starts to grow.
Intermmediate forest
After the grass has carpeted the floor then small pines and spruces grow.
Climax community
The biggest and last point of any forest. Where all of the big pine trees and birch trees grow
