• Reduces loss of soil moisture by cooling the soil.
• Reduces local air temperature.

Windbreaks
• Reduce soil moisture loss by reducing evapo-transpiration.
• Warm areas in cool weather by reducing the wind chill factor.
• Prevent soil erosion.

Importance of Plants to Man
Erosion Control
• Roots capture soil particles as they wash across the surface of the ground.
• Leaves capture and slow rain water so soil particles are not so easily dislodged.
