Early settlers could get a free quarter section of land if they built a home and lived on it for a minimum of 5 years. Also, they had to plant a wind row consisting of 1/4M of trees that thrived. In the Hutchinson area they planted hedge trees because they were easy to grow. The area around Hays, they planted cedar trees or cottonwood trees.
I'm sure SD knows what they planted around the Dighton area.
