SUCCESION

• Life coming back after a series of disasters
• There are two types; PRIMARY & SECONDARY

PRIMARY SUCCESSION

• Primary succession is when no soil is left
• After a disaster. This is called "bare rock"
• The 1st life to come back is lichens and mosses
• Ex. Volcano

SECONDARY SUCCESSION

• When soil remains after a disaster has happened.
• The first life to come back are lupines and lodge pole pines.
• Ex. Landslides and wildfires

PIONEER SPECIES AND CLIMAX COMMUNITY

• Pioneer species- the first life to come back.
• Climax- the slowest growing but longest lasting species.
