Interaction of traditional use of marine resources with competition
Management Concern: Moderate
Adequacy of Information: Low
Summary extracts from Outlook Report 2009
- Competition between corals and algae appears normal except for some inshore areas, but there is little information about other types of competition.
- It can be assumed that reductions in the populations of species such as dugongs, marine turtles, predatory fish and sea cucumbers have affected natural competitive processes.
