Interaction of ports and shipping with Dugongs
Management Concern: High
Adequacy of Information: Moderate
Summary extract from Outlook Report 2009
- Numbers of dugongs have declined drastically along the 'urban coast' but may now be stabilising. The remote coast population does not appear to have changed.
- Most routine shipping activities have negligible consequences. Dredging and construction of port facilities can have significant but localised impacts.
