- Human Activity
- Afforestation
- Plant trees for timber
- Pine forests - human plantations
- Prevents climatic climax being reached
- Only one species is planted and managed so this species dominates
- Trees may be cleared to make room for the sapling
- Deforestation
- Hardy shrubs e.g. heather
- Wood for timber for fuel or space for farming
- Prevents climatic climax being reached
- Reduces soil quality
- Nutrients removed
- Few plants can grow in poor soil
- Reduces soil quality
- Animal Grazing
- Fast growing grasses and plants e.g. Dandelions. Very few trees and shrubs
- Domesticated animals graze for food
- Prevents climatic climax being reached
- Small plants and saplings are eaten or destroyed (trampled) before they can grow
- Clearance by fire
- Clear an area for farming, control plants growing or improve the soil in an area
- Fast-growing plants whose roots aren't damaged by fires e.g. heather
- Prevents climatic climax being reached
- Plants are destroyed and the fastest growing plants recolonised
- Afforestation
