The 1930s Dust Bowl taught us that plants play a critical role in the health of our environment. At that time, the U.S. Department of Agriculture (USDA) created a number of Soil Conservation Nurseries throughout the country to grow and distribute plants for the stabilization of severely eroding lands. Since the mid-1930s, this need for conservation plants has grown into the present day Plant Materials Program. The Program was created in 1935 as the Soil Conservation Service (SCS) Division of Nurseries. It later became the SCS Plant Materials Program and is known today as the NRCS Plant Materials Program.
