Conclusions
Large Wood plays an important ecological role in
lakeshore habitat
Lakeshore development threatens the ecological
integrity of shoreline habitat

• Placement of wood as mitigation should only occur
  in areas that would naturally
• accumulate wood

Distribution and abundance of wood depends on
supply, wind, waves and currents
