1. Diversity and intact processes e.g. Palumbi et al 2009 

2. Beach diversity is hardly recognised• Unique fauna & flora• Most are endemic

3. Beach processes are underappreciated• Cycle C faster than 

rainforests Coupland et al 2007

1. Linear, narrow ecosystems

2. Fragmented alongshore3. Legacy of poor coastal

• Commitments to international conventions

– Coast is sufficiently intact– International best practice– ICM Act (2008)

• Current “challenges”– Management is local– No national plan

Status of coastal conservation and m anagem ent in SA

Future for the SA coast

• Local management, but a national plan• Beaches don’t need MPAs• Next step – include all coastal ecosystems

– MPAs will be required
