Factors Effecting the Global Pattern of Vegetation
Climatic factors
Precipitation
Precipitation is considered to be the limiting factor that determines whether the biomes of the world's land surface are forest grassland or desert.
Timing
.
If most of the rain falls in summer, when evaporation rates are especially high there may be inadequate soil moisture to support trees and grasslands
Avaliability
What availability is scarce in places like deserts. This causes fewer living things to stay alive. the little rain that is received profuses growth in plants that have a very short lifetime.
Tempreture
Each plant is different and needs different tempretures to live the mos common tempretures are between 10 °C and 35 °C.
Light
All green plants need light ( sunlight ) The leaves on plants take in the sun collecting the sun's energy using it to combine carbon dioxide and water to create nutrients.
Wind
In high wind areas plants need to be able to survive winds can cause physical damage to plants causing the plant to grow in asymmetrical shapes.
Topographic Factors
Slope
The slope is important because it determines how much water can stay in the soil which evaluates how many plants can get full growth because of the angle of the slope.
Aspect
Slope alters sunlight and temperature conditions. North facing slopes facing the southern hemisphere get more growth especially in winter.
Altitude
Increasing elevations means a decrease in soil depth and air temperature there is also an increase in wind exposure which reduces plant growth.
Endaphic Factors
Soil related factors
Most Plants need soil as a medium in which to grow because the soil contains nutrients air and water that plants need to stay alive. Their fore soils and vegetation have an intimate mutual relationship.
Biotic Factors
Plant competition
Plant Competition can be an important factor controlling plant communities, along with resources, disturbance, herbivory, and mutualisms.
human Influence
Humans are also biotic factors in the ecosystem. Other organisms are affected by human actions, often in adverse ways.
