Field shelterbelts are an important conservation management tool on many farms in
Alberta. These bands of trees and shrubs are effective barriers to the wind,
providing protection to the adjacent soil and crops. Shelterbelts can trap snow
and increase the available moisture content of the nearby soil, improving
adjacent crop yields. Other benefits include improved aesthetics and, if managed
appropriately, wildlife habitat.
CASCI, the Alberta Field Shelterbelt Program made trees and shrubs available to
farmers and non-profit groups free of charge for shelterbelt plantings. In
addition, most municipalities have a shelterbelt program to complement tree
orders from Alberta nurseries. Between 1989 and 1996, 4.5 million field
shelterbelt trees were planted. This is equivalent to about 4,500 kilometres of
wooded areas have many environmental benefits ranging from soil conservation and
water quality protection to biodiversity and wildlife habitat enhancement.
Proper planning and sustainable management of these areas can improve
environmental stewardship. As their awareness of sustainable management
increases, landowners are becoming more selective in the management choices they
make. Overall, shelterbelt and woodlot education is proving an effective way of
minimizing the potential for environmental damage.
