Control of wildling conifers in the Wakatipu is going backwards, a consultant warned the Queenstown Lakes Community Services committee at its monthly meeting on Tuesday.

Go-Green consultant Colin Day told the committee that the problem of wildling pines in the district needed $1 million to make a "big hit" in one year to arrest their spread, which had become noticeably worse in the past 25 years.

Mr Day compared images of the Wakatipu landscape in the 1980s and the present to show how the trees had invaded land.

Areas such as Queenstown Hill and Bowen Peak were obvious examples where conifers had colonised the bare land, he said.

The issue was addressed in the draft Wakatipu wildling conifer strategy, an update of the previous one presented to the committee, and outlined a strategy of control through until 2012.

After questions from Cr Cath Gilmour as to why the owner of Coronet Peak Station was not forced to comply with requirements to control wildling conifers, and a call from her and other councillors for greater input from Otago Regional Council on pest management, the committee accepted the draft strategy to be put out for public comment.

Wakatipu wildling conifer strategy key points

• The first Wakatipu wildling conifer strategy covered the period 2004-07.

• The latest draft Wakatipu wildling conifer strategy covers the period 2008-12.

• Objectives are:

1. To meet the local communities' desire to see wildling conifers controlled.

2. Clarify the wildling control responsibilities of QLDC, other administering agencies, landowners/managers and the general public.

3. Determine a strategically scheduled and cost-effective control programme.

4. Promote awareness and education relative to wildling issues.

5. To improve support for a wildling control programme.

• The 2004-08 strategy was reviewed to determine the success of the programme and prioritise future work as outlined in the latest strategy.

• On average $111,000 was spent annually on control between 2004 and 2008. The new draft strategy recommends budgeting $120,000 per annum for wildling conifer control for 2009 onwards.

• Priority areas for the next four years are Gooseberry and Horse Gullies, Coronet Slopes, Ben Lomond ridge, Bowen Peak, Wedge Peak, Upper Bushy Creek and Queenstown Hill.

• Buy-in by landowners and other administrators was essential for ongoing success, although complete eradication was not possible.
