Wetlands andMigratory Birds
OVERVIEW
• Rationale for these BMPs
• Wetlands
• Migratory Birds
RATIONALE
• Continued waterpower development in Ontario
• BMP Guide (2012)
• Identified gaps
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
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
MITIGATION
• Protection
• Enhancement
• Restoration
• Creation
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
SPECIFIC MITIGATION - ENHANCEMENT
SPECIFIC MITIGATION – RESTORATION
& CREATION
MIGRATORY BIRDS
• What are they
• Relevant policies
• Relation to waterpower
MIGRATORY BIRDS
MIGRATORY BIRDS - MITIGATION
• Avoidance timing for clearing, de-watering and flooding
• Dust control
• Directional lighting
• Speed limits
• Exclusion fencing
• Noise control
MIGRATORY BIRDS - ENHANCEMENT
• Artificial nesting structures
• Retaining backbay areas during headpong filling
• Mudflats for shorebirds
