the pest and disease information database for forestry This site is updated on a regular basis. If you would like to contribute material, or enquire about this database or inform us of dead links or other problems with the site, please email the pest and disease site administrator, Dean Satchell at dsatch@xtra.co.nz This database has so far been put together from the complete archive of Forest Health Newsletter articles, the Forest Timber and Insects leaflets and the Forest Pathology leaflets along with papers from the Forest Health Collaborative. Contributions are very welcome!

Much of the economic success of this forestry enterprise can be attributed to the fact that these trees are grown in exclusion of the numerous insects and diseases in P. radiata’s native range (and elsewhere in the world) that limit its growth and survival. As such, biosecurity, much like genetic improvement, silviculture and fire suppression, represents a critical component to the economic success of forestry in the country. Investment in biosecurity by the forest industry thus is likely to yield tangible economic benefit in the form of exclusion of at least some pests that would otherwise reduce profit from the forestry enterprise. Without biosecurity, incursions of new pests are likely to occur, though identifying the time, location and identity of invaders would be impossible to forecast. Thus, the return on investment in biosecurity can be expreducing the probability of such incursions. From MAF Biosecurity New Zealands Strategic Plan: The biosecurity system outcomes, which we have responsibility for delivering, are to: • Prevent harmful organisms from crossing New Zealand’s borders and establishing, while ensuring trade and tourism are maintained. • Reduce the unwanted harm caused by organisms already established in New Zealand, and to • Support New Zealanders to be informed and involved participants in the biosecurity system. It is critical to MAFBNZ’s success that everything it does aligns to these outcomes. To achieve them, MAFBNZ works in three separate but interrelated geographic zones: Global, within New Zealand and at Pathways and Borders.MAFBNZ’s strategic direction comprise seven goals which will drive our priorities over the next five years. 1. to provide effective leadership across the biosecurity system 2. to make timely and informed decisions 3. to have more effective interventions at the border 4. to work collaboratively across organisations for better biosecurity outcomes 5. to see that everyone takes responsibility for biosecurity risks and interests 6. o identify and prepare for emerging threats and risks 7. to attract and retain the right people Who pays to stop the invaders? opinion piece By NZFOA executive director David Rhodes, from The New Zealand Forestry Bulletin, Autumn 2008 (Source NZFOA) When it comes to biosecurity, forest owners are unique. We are the only primary industry to have a formal surveillance programme for plant pests and diseases, funded by growers themselves. However, the programme is not formally linked with other surveillance programmes - despite the close personal contacts we have with MAF Biosecurity staff and biosecurity researchers at Scion. And it doesn't cover small forest blocks, shelter belts or the indigenous estate. Linking all the biosecurity strands together, as part of a coherent policy applying to all sectors, is therefore vital. This need was identified in the Prime Report for MAF in 2002 and in the NZ Biosecurity Review of 2003. MAF plans to do this in its new Biosecurity Surveillance Strategy due to be released for stakeholder comment in May. As part of the development of this strategy, MAF is reviewing who should decide whether an exotic organism is contained or eradicated, and who should pay. These are important questions. The budget for painted apple moth eradication in Auckland in 2003/04 was more than $51 million - a large sum. But it would have been a fraction of the annual economic cost of controlling the moth in forest plantations if it had got away - quite apart from the destruction it would have wrought in native forests, gardens and parks. A proposal that MAF Biosecurity should work in partnership with affected sectors in preparing for and dealing with incursions like this is to be applauded. But the suggestion that they should also jointly fund such activities is a more complex issue. In various policy papers, MAF argues that those who contribute to an incursion ('exacerbators'), if they can be identified, may not have the resources to contribute to the response. This draws the ministry to conclude that "funding from importers seems unfair and inefficient" and that "beneficiaries are better placed to pay than exacerbators". The NZFOA does not accept that this conclusion is logical. Also, it runs contrary to the polluter-pays principle and sends the wrong signal for influencing behaviour. Just like trampers and hunters, who have to pay for control costs if their campfires spread to the surrounding forest, importers need to know they will be liable if pests spread from their shipping containers into the surrounding environment. On a practical level too, an industry battling with a new organism may well have very little ability to pay - especially if leads to the loss of overseas markets, or if yields and quality are severely compromised. The NZFOA accepts in principle that there can be circumstances where it would be appropriate for an industry to contribute to an incursion response. But... • The industry would need to be getting a disproportionately higher benefit than society at large
• Exacerbators would have been identified and required to pay their share
•
The efforts of the industry to prevent or minimise the impact of an
incursion through surveillance, research etc, would have been taken
into account
• Other
beneficiaries would be contributing on the same basis. With forestry,
we imagine this might occur if an exotic organism arrived in the
country unassisted, with effects that were largely restricted to one or
two plantation species - a very unusual event.
Because of this, we believe the policy reviews should focus on ensuring that New Zealand has a coherent and integrated biosecurity framework covering surveillance, readiness, response and recovery. It would indeed be unfortunate if this focus was lost in squabbles over 'who pays' in a range of unlikely hypothetical scenarios. Last updated April 2008 Dean Satchell |
