Wind, Wind Erosion, Sand Storms and Dunes
Photograph of a partially completed pattern of windbreaks in eastern Foard County, Texas. The barren areas paralleling some windbreaks are not always due to sapping—incomplete patterns permit heavy, sterile sand to drift up to the windbreak on exposed sides. This situation can eventually be remedied by completion of the pattern and the planting of legumes on damaged areas. TX-79, 510.
