� Primary cause is global warming
� Why is sea level rise a problem?
� How the CRC has reacted to sea level rise
Coastal Erosion
� Coastal Erosion is a natural process � Abrasion � Hydraulic Action

How Dredging Affects Sea Turtles
� In-water � Possible Threats
� Entrainment
� Direct Hit � Turbidity
� Noise
� Mitigation � Sea Turtle Observer Program
� Turtle Deflecting Draghead
� Acoustic Tagging � Cutting
How Dredging Affects Sea Turtles
� On-land � Possible Threats
� Disposal of Dredged Material � Quality of Sand � Slope of Sand
� Covering of Sea Turtle Nests � Light Pollution � Hazardous Machinery
� Mitigation � Monitoring of Project Sites � Relocation of Nests � Remove Trash and Debris � Native Beach Quality Sand � Slope of Beach should be monitored � Compaction of Sand
Conclusions
� The protection of our Sea Turtles is important
� Sea Turtle Monitors should be recognized and funded
