Establishment of dense vegetation in a linear design to achieve a natural resource conservation purpose.

Permanent vegetation increases soil organic matter in the footprint of the practice.

Typical Landuse:

Not Applicable

Tall vegetation will trap snow upwind of structures and animal concentration areas.

Not Applicable

Not Applicable

Root development in the footprint of the practice will improve soil structure and porosity.

Not Applicable

Not Applicable

Not Applicable

Not Applicable

The action reduces pesticide drift and may reduce runoff and erosion. Also, the borders may attract beneficial insects or trap insect 

pests which reduce the need for pesticide applications.

Not Applicable

Nutrients from runoff are removed when the strips of vegetation are established where they can intercept overland flow or wind-borne 

soil.

Not Applicable

Not Applicable

Use of this practice along small streams increases shade and moderates stream temperatures.

Not Applicable

Selected plants improve food supply and availability.

Permanent rows of trees or shrubs can reduce wind erosion and intercept and trap airborne particles.

Not Applicable

Vegetation removes CO2 from the air and stores it in the form of carbon in the plants and soil.

Can be used to intercept and filter odorous gases.

Plants selected will be maintained at optimal growing conditions for the intended purpose.

Plants selected are adapted and suited. 

Vegetation is installed and managed to control undesired species. 

Not Applicable

Not Applicable

Not Applicable

Not Applicable

Selected desirable plants improve cover for wildlife.

Not Applicable

Provides additional vertical habitat/space.

Not Applicable

Hedgerows can provide some shade and protection from wind.
