Windbreaks provide protection from prevailing winter winds. In Iowa, these are generally from the north and west. Our windbreak was established in 1982 on the north side of the 40-acre site and stretches from the buildings to the western most boundary. Deciduous shrubs make up the northernmost row with large conifers, notably Eastern white pine, arborvitae, and Colorado spruce in the second row. Use of a variety of species in a windbreak decreases the risk of a single disease or pest affecting an entire windbreak.
