Greetings birding-aus members
This is a second attempt to send this message as it seems not to have been
deliverable last time round. I trust it is of relevance to members on this
list.
You might remember the series of emails regarding the salvinia infestation
at Longneck Lagoon some time back. I wrote as Secretary of the National
Parks Association to the Director, Central NPWS, Bob Conroy making some
inquiries and he has now replied.
In his response he states that:
1. The NPWS has commenced management of this weed and is presently
finalising a Review of Environmental Factors document. This must consider
the requirements of the Commonwealth Environment Protection and Biodiversity
Conservation Act, 1999.
2. The presence of the weed and the proposed control methodology have both
support and opposition from within the community.
3. The long term impact of the use of herbicide in the Lagoon in particular
has to be properly assessed.
4. The eradication of salvinia in this waterbody is not expected to be easy.
5. The proposed methodology involves mechanical harvesting to reduce the wed
biomass followed by the application of a specific (unstated) herbicide to
the remaining weed. There will then follow an intensive monitoring
commitment and "spot" action against any remaining weed presence.
6. The control of the weed within the catchment is also being pursued by the
NPWS.
I am sure birding-aus members will be interested to hear of progress and I
look forward to hearing your own reports as to how this operation proceeds.
Note, I am not referring to any timeline and nor did Bob Conroy.
