Exam 20: Succession and Stability

You are restoring a previously farmed area to the historic prairie community. You add seeds of pioneer species that are known to fix nitrogen. You then place enclosures over your seeded areas. The enclosures allow light and water to reach the seedlings, but keep insects, mammals, and birds out. What successional factor(s) have you managed with your actions? (Select all that apply.)
