Success in containing the South African oxygen weed
lagarosiphon in Lake Wanaka is expected to lead to a
concentration of weed control work nearer to Wanaka.
Land Information Minister Maurice Williamson said yesterday
''great progress'' was being made to improve the health of
Lake Wanaka through efforts to rid it of the weed, which
Mr Williamson said access had been improved to many parts of
the lake, including Paddock Bay and Bishops Bay, which were
previously clogged with dense weed beds.
The control work is carried out by a lagarosiphon management
committee, led by Land Information New Zealand.
The committee has now recommended the containment line be
moved further south to extend from the southern tip of the
Lake Wanaka Peninsula to the very southern end of Bishops
Moving the containment line south meant lagarosiphon was
being effectively controlled in a large part of Lake Wanaka,
and weed-control efforts could be directed to areas more
heavily used for recreation closer to Wanaka, Mr Williamson
