| ||Field shelterbelts conserve soil, protect crops, trap snow, provide wildlife habitat and beautify the landscape.
This information about shelterbelt species and recommendations for their suitability for various locations in Alberta. The recommendations are based on a 1991 survey. Recommendations are divided into three categories:
The recommendations are based on the plants being planted on non-irrigated sites with proper care and management practices being strictly followed. The Species Suitability Maps provide a general guide only.
- Recommended Area (shown on map with triangles): species is best suited for planting in this area.
- Satisfactory Area (shown on map with lines): species is less suited for planting in this area due to one or more of the following:
- moisture or climatic limitations
- winter dieback
- insect pests
- additional care and management required
- Unsatisfactory Area (shown on map as white area): species performs poorly in this area
Moisture and climate conditions, and insect and disease levels may vary within a given area.
Exceptions to the recommendations may apply if:
Guide to Plant Characteristics
- irrigation water is available for tree use or the planting site is a low lying area (higher soil moisture levels).
- the planting site is a well protected area (excellent microclimate) and exceptional care and management practices are followed.
- the planting site is in a "transitional zone" (a small zone along the boundary between two different recommendations).
Height at maturity, useful life, and growth rate depend upon moisture conditions, cleanliness, location and exposure
- the smaller numbers are the height, useful age, and growth rate that could be expected in FAIR growing conditions.
