Check out a nice guide from Agriculture & Agri-Food Canada entitled “Shelterbelts – Design Guidelines for Farmyard, Field, Roadside, Livestock, Wildlife and Riparian Buffer Plantings on the Prairies.”
Get Windbreaks for Conservation from USDA National Agroforestry Center. It is an excellent guide to design considerations for conservation windbreaks.

They have additional windbreak publications including Windbreaks for Wildlife, How Windbreaks Work, & many other more detailed aspects of windbreak design, establishment and management.
