DUTCH ELM DISEASE, AUCKLAND (Disease Management programme)
Fiona Bancroft, from MAF BNZ Report to Forest Biosecurity Consultative Committee, July 31 2008
- MAF Biosecurity New Zealand is no longer coordinating or contributing funding to the national Dutch Elm Disease control programme following a decision that national management of the disease is not a priority when compared to other organisms that threaten the health and lifestyle of New Zealanders, our environment and our cultural and economic wellbeing.
- MAF Biosecurity New Zealand is now actively working to transfer the programme to Auckland City Council over an 18-month period, including agreed transition arrangements (e.g. MAF Biosecurity New Zealand maintenance of regulatory movement controls). Auckland City Council staff are currently developing a long term position, however this has yet to be formally tested with and approved by their council.
- MAF Biosecurity New Zealand has informed all Territorial Authorities of this decision and the new funding arrangements. MAF Biosecurity New Zealand is in the process of contacting each of the Territorial Authorities park managers to discuss what this means for them.
- MAFBNZ has issued a public statement about changes to the Dutch Elm Disease programme.

SCOLYTUS MULTISTRIATUS ON THE MOVE
From Forest Health News No. 185, June 2008
The smaller elm bark beetle, Scolytus multistriatus, was first found
in New Zealand in Myers Park, Auckland in 1990. This was when
Dutch elm disease, caused by the fungus Ophiostoma novi-ulmi,
was found in here. S. multistriatus is an important vector of the disease.
The beetle was first found outside the Auckland region in 1996 when it
was found in Waikato. In 1997 it was also found in Bay of Plenty. In
March this year many S. multistriatus were caught on pheromone traps
in Taupo and Napier and larvae and adults were found in a dead
Ulmus procera branch in Napier. No beetles were trapped on other traps
in Wairarapa, Wellington, Picton, Nelson, Richmond, and Christchurch.
Note that although S. multistriatus is now quite widespread that Dutch
elm disease is still confined to Auckland.

| Elm infected with Dutch elm disease. |
Simon Cook (Auckland Council) raised the issue of Dutch Elm Disease (DED) , advising the Committee that three more infected trees had been found – two golden elms and one corpus. Huge numbers of beetles have been trapped, far more than in previous years. 4 have been confirmed as carrying the disease. The three new trees are all in areas not funding the programme. All the Councils in Auckland are contributing to funding, along with three private organisations.
Dutch Elm Disease, Auckland (Disease Management Programme)
Don Hammond (From NZIF newsletter Number 2007/26 – 6 July 2007)
Biosecurity New Zealand and currently affected territorial local authorities (TLAs) have continued an interim Dutch elm disease (DED) management programme in 2006/07. The programme objectives are to prevent or stop the disease spread and to control its impacts in greater Auckland.
During the 2006/07 season one full survey of all elms in the high risk areas has been conducted at the beginning of the season. Approximately 75 % of the highest risk elms have been inspected in the second part of the season. There has been an additional special survey conducted in parts of the Waitakere City.
Beetle trapping programme has been operated in parts of some of the highest risk areas.
There have been three elms detected with the disease throughout the season as well as one beetle positive for carrying spores of the disease.
Biosecurity New Zealand will be contacting TLAs shortly to advise its current position and to provide one final opportunity for them to express effective interest in the DED management programme. Biosecurity New Zealand’s level of continued involvement in the programme will be based on the combined financial commitment from TLAs.
