Chapter 7 Prairie Woodlands
  1. Prairie ecosystems are often interspersed with woodlands populated by trees.
  2. River and stream banks provide moisture and fire breaks for trees, which can form savannas and denser riparian forests.
  3. Human suppression of fires and planting trees have caused the intrusion of woody trees into grasslands and expansion of woodland birds.
  4. The increase in woodland-grassland boundaries may also lead to increase of edge-adapted species.
