ScienceUS Planted 220 Million Trees in 1930s to Combat Dust Bowl Erosion
During the 1930s Dust Bowl, the US government planted over 220 million trees across 33,000 shelterbelts in the Great Plains to prevent soil erosion. This Prairie States Forestry Project, active from 1935 to 1942, spanned 18,600 miles across six states. Many of these tree lines still protect working farms nearly 80 years later, a New Deal effort led by Forest Service administrator Paul Roberts.
