Battle against undaria carries on
The Fiordland Marine Guardians would like to clarify that, contrary to Lloyd Esler’s statement (February 21), efforts to control the invasive Asian kelp undaria in Breaksea Sound, Fiordland, have certainly not been ‘‘abandoned’’.
Mr Esler refers to undaria as ‘‘the gorse of the sea’’ and details a number of ways that it can change marine ecosystems, seemingly irreversibly. On these points we are in agreement.
We fear that this insidious weed may smother the unique and worldrenowned rock wall communities in Fiordland, for example, taking up real estate on black corals.
In other parts of the country, the kelp has been observed growing on the backs of rock lobster.
It can grow anywhere and everywhere. It really is the gorse of the sea.
This is why we are working with the regional council, DOC, MPI and the Fiordland community to try and contain undaria within Breaksea Sound.
However, ultimately it comes down to those on the water playing their part. It is more important than ever that boaties take responsibility by ensuring their hulls are clean and well maintained, and that they have a Clean Vessel Pass.
We also expect all boaties to familiarise themselves with the extent and requirements of the Controlled Area that is in place in Breaksea Sound.
We have not given up in the fight against undaria in Fiordland. Rebecca McLeod Chairperson
