I'm doing research on South Dakota Prairie Grass and I want to know
1) what plant varieties grow in SD,
2) how long (or what criteria is needed) before a prairie field is certified true prairie,
3) If someone was to cut sod from a prairie grass field, will it grow back with the same plant species, and will that new growth be considered true prairie grass?
Thank you in advance for your time and expertise.
