• In the early 1930s there were millions of acres of extensively degraded grazing lands and abandoned and eroded cropland in the Northern Plains of the United States and Canada. • Grass breeding and plant materials programs were established by both the US and Canadian governments and cooperating universities to develop revegetation materials. • Efforts of a small number of research locations and people resulted in grass cultivars or varieties that were used to revegetate and preserve the soil on millions of acres of land. • This is a brief history of the people, agencies, and universities that developed these cultivars that restored and increased the productivity of grasslands in the Northern Plains
