Attached is a workshop presentation Brett Woodman gave May 5 to the Ontario Waterpower Association with respect to the 2 new Best Management Practices we prepared for wetlands and migratory birds during waterpower construction.

Ontario Waterpower Association Workshop
Best Management Practices
Wetlands and
Migratory Birds

2. OVERVIEW
• Rationale for these BMPs
• Wetlands
• Migratory Birds

3. RATIONALE
• Continued waterpower
development in Ontario
• BMP Guide (2012)
• Identified gaps

4. WETLANDS
“lands that are seasonally or permanently flooded by
shallow water as well as lands where the water table is
close to the surface…”
4 types of wetlands
• Marsh
• Swamp
• Bog
• Fen

5. KEY CONSIDERATIONS
• Different types of waterpower
• Construction can have negative
impacts
• Opportunities are best identified
early in the planning process
• Clear demarcation of boundaries
• Maintain hydrological balance
• Mitigation must consider wetland
type and sensitivity

6. MITIGATION
• Protection
• Enhancement
• Restoration
• Creation

7. SPECIFIC MITIGATION - PROTECTION
• Hydrogeological study
• Minimize soil compaction
• Seasonally timed
• Appropriate erosion control
• Roads (location, maintenance)
• Wildlife
• Invasive species
• Sod mats
• Culverts
• Placement of fill

8. SPECIFIC MITIGATION - ENHANCEMENT

9. SPECIFIC MITIGATION – RESTORATION
& CREATION

11. MIGRATORY BIRDS
• What are they
• Relevant policies
• Relation to waterpower

12. MIGRATORY BIRDS

13. MIGRATORY BIRDS - MITIGATION
• Avoidance timing for clearing, de-
watering and flooding
• Dust control
• Directional lighting
• Speed limits
• Exclusion fencing
• Noise control

14. MIGRATORY BIRDS - ENHANCEMENT
• Artificial nesting structures
• Retaining backbay areas during
headpong filling
• Mudflats for shorebirds
