SHANNON CREEK
Where have the threatened species gone.
September 2007
Approval to build the Shannon Creek dam was conditional. Among the numerous
conditions imposed was a requirement to monitor the health of threatened species at
the site for eight years, including five years after completion of works, to
“assess the
effectiveness of the mitigation measures claimed in the EIS"
(Commission of
Inquiry report, 2000, page 53).
The initial expectation was that all threatened species identified at the site would be
included in the monitoring program. Subsequent investigations by Clarence
Environment Centre members, however, revealed a number of threatened species that
had been 'overlooked' by the EIS. These, and the listing of more species over time,
meant the threatened species initially identified at Shannon Creek more than doubled
in number, from some two dozen to over fifty by the time monitoring began in 2004.
As a result, the Department of Environment and Conservation (DEC), has allowed
the numbers of species to be monitored to be culled to less than half. Today the
monitoring program covers:
Fauna -
•
10 threatened species of micro-bats;
•
Brush-tailed Rock-wallaby (endangered)
•
Koala (vulnerable); and
•
Black Bittern (vulnerable);
Flora -
•
Melichrus hirsutus
(endangered).
•
Lindernia alsinoides
(endangered).
•
Phyllanthus microcladdus
(endangered).
•
Bertya longistyla
(endangered), and
•
Amorphospermum whiteii
(vulnerable)
Endangered communities -
•
Brown Bloodwood – Sandstone Mahogany
•
Hoop Pine Dry Rainforest
•
Coastal Freshwater Wetland Forest, and
•
Coastal Swamp Sclerophyll Forest
Key threatening processes -
•
Invasion by the dieback pathogen,
Phytophthora cinnamomi.
•
Invasion by exotic grasses (weeds monitoring program)
•
European Red Fox (vertebrate pest monitoring program).
The program may change in the future as circumstances change.
