Barrier Effect of Vegetation

Vegetation impedes the movement of airborne substances such as dust and aerosols (including agricultural chemicals and industrial and transport emissions), enhances air mixing and mitigates noise.



Regulating Functions

How does the barrier effect of vegetation contribute to ecosystem service provision?

Vegetation provides a barrier between cultivated ecosystems and adjacent ecosystems.

The map to the right shows areas where the function barrier effect of vegetation is expected to occur across SEQ. Data sets supporting the map can be found in the Quick Index. By clicking on the link below the map it will provide a more detailed view.


How do we know if we are degrading, maintaining or improving the barrier effect of vegetation in SEQ?


Trees along man-made transport infrastucture can mitigate noise and impede the movement of air-borne pollutants.

Vegetation not only protects adjacent ecosystems from agricultural emissions, but agriultural crops from airborne pollutants derived from adjacent ecosystems.
