From ANIMAL PEOPLE, Jan/Feb 1997:
Fewer than 2,000 dugongs persist along the
Australian east coast and southern Great Barrier Reef, as
numbers have crashed from 50% to 80% in recent years,
partly due to storms and coastal development which have
devastated the sea grass that Australian dugongs depend on
for food, but to greater extent as the result of gillnetting,
which accounted for 15 of 30 recent dugong deaths at Great
Barrier Reef Marine Park, according to Helene Marsh of
James Cook University. Shark nets alone caught 654
dugongs off central Queensland in 1995, along with 651 dolphins
and 4,059 sea turtles. Only 45 dugongs, 31 dolphins,
and 1,420 turtles survived. Nine newly established protection
zones off Queensland may not help, warns North Queensland
Conservation Council coordinator Jeremy Tager. “The reality
is, there is no new protection from human threats to
dugnongs in these areas,” he said.” Gill netting, hunting,
coastal development, vessel traffic, and even the use of
explosives will continue in the proposed protection areas.”
