What Causes Biomes and Vegetation to Change?

Biomes are areas of land with similar climates, plant species and animal life. The vegetation of a biome is determined by factors such as temperature, precipitation and elevation. These factors are constantly changing, both naturally and due to human activity, which can result in changes to biomes and the vegetation within them.

Natural Changes

The following are some natural causes of change in biomes and vegetation:

  • Climate Changes: Climate change has wide-reaching effects, resulting in changes to temperature, precipitation and sunlight levels. Long-term changes to these factors can impact the vegetation in an area, as certain species may become better adapted to the new climate and others may disappear.
  • Natural Disasters: Natural disasters, such as floods, storms, and wildfires, can have a drastic impact on the vegetation in an area. Wildfires, for example, can destroy entire forests, while floods can cause plants to become waterlogged and die.
  • Migration: Migration of plants and animals can also contribute to changes in biomes. When an animal or plant species moves into a new area, they may introduce new resources and introduce competition to the existing species.

Human Activity

Humans are often the greatest drivers of change in biomes and their vegetation. The following are examples of how human activity can impact biomes and the vegetation therein:

  • Deforestation: The removal of forests for timber or human settlements can have drastic effects on the vegetation in an area. Removing trees can reduce the amount of shade and change the climate, leading to some species thriving in the new conditions and others being unable to survive.
  • Intensive Agriculture: Intensive farming methods, such as using chemical fertilizers and pesticides, can cause damage to entire ecosystems and change the vegetation in the area. In addition, intensive farming can lead to soil erosion and the destruction of habitats for certain species.
  • Anthropogenic Pollution: Pollutants such as heavy metals and sulfur dioxide can damage vegetation and disrupt its ability to photosynthesize. As air and water pollution is often linked to human activities, it can have a wide-reaching impact on biomes and the vegetation that they contain.

The effects of human activity on biomes and vegetation are often more destructive and long-lasting than those of natural causes. As such, reducing our impact on the environment is essential in order to protect the world’s biomes and the unique ecosystems that they contain.


Biomes and vegetation are constantly changing due to both natural causes and human activities. Understanding and mitigating the human causes of disturbance is essential in order to ensure that our biomes and the species that inhabit them are protected for future generations.
