STANDARD SHELTER BELT PLAN 12 -e ft eee. .|2.50 | 5.00 (10.00 
(Recommended by the University of Minnesota) 23a tte 
MODEL FARM WINDBREAK 
Rows 1 and 2. Siberian Pea Tree, Russian Olive, Honeysuckle, 
Laurel Leaf Willow, Arborvitae or Juniper. 
Rows 3 and 5. Niobe Willow, Golden Willow, Lombardy Poplar, or 
Chinese Elm. 
Rows 4 and 6. Green Ash, American Elm or Silver Maple. 
Rows 7 and 8. Ponderosa Pine, Jack Pine, Norway Pine or White 
Pine. 
Rows 9 and 10. Colorado Blue Spruce, Black Hills Spruce, Norwdy 
Spruce, White Spruce, Douglas Fir, Arborvitae or Juniper. 
All trées and shrubs planted ‘in the shelter belt should be staggered 
to fill up the gaps and thereby to more effectively check the wind. 
The spacing between rows is shown in the plan. These distances may 
be extended by 2 to 4 feet in the main windbreak (rows 3 to 10) if 
space is available. The trees or shrubs used in the snow catch (rows 
1 and 2) should be planted 4 feet apart in the row; all other trees 
should be planted 6 feet apart in the row. The trees in rows 3 and 5 
may be cut for fuel or posts whenever they begin to crowd the 
more hardy, long-lived trees in rows 4 and 6.
