Is aerial 1080 needed to control Tb?

The ERMA Reassessment of 1080 found problems with both the economic and practical arguments used to support aerial 1080 for Tb control

2007	ERMA Agency Appendix J: Cullen	P 580	Environmental Risk Management Authority Reassessment of 1080	“The Application…fails to demonstrate evidence or understanding of economic research on use of 1080, pest control or Tb..this section of the application is unsophisticated, uses crude approaches to estimate even the largest benefits and costs associated with the use of 1080, lacks awareness of many pertinent economic research techniques, seems unaware of almost all relevant economic research”
2007	ERMA Agency Appendix J: Cullen	P 582	Environmental Risk Management Authority Reassessment of 1080	“No research is cited in the Application that studies the dollar losses occurring from the loss of one or more export markets [due to market perceptions of NZ’s Tb status, however] Clough & Nixon (2000) conclude..a trade ban would be difficult to sustain under current international trade rules, the risk is very small and the expected value of an avoided trade ban is modest”
2007	ERMA Agency Appendix K: Ford	P 596	Environmental Risk Management Authority Reassessment of 1080	“Justification for the assessment of this impact [decreased likelihood of loss of markets due to market perceptions of NZ’s Tb status] as E is scant..it is doubtful that a combined assessment of both very likely and of a major magnitude are a credible combination”
2007	Agency Appendix K: Ford	P 591	Environmental Risk Management Authority Reassessment of 1080	“There is no apparent discussion on the robustness and reliability of this epidemiological monitoring [of Tb prevalence in the future]. There is no discussion or information provided about the risk or sensitivity parameters of the modelling carried out”
2007	Agency Appendix G	P 540	Environmental Risk Management Authority Reassessment of 1080	“The applicants..have provided very limited supporting information to demonstrate the importance of aerial 1080 operations in terms of controlling possums and the subsequent effect on the prevalence of Tb”
2007	Agency Appendix G	P 540	Environmental Risk Management Authority Reassessment of 1080	“The applicants have not referenced the statement [that possums are the main maintenance hosts for bovine Tb in NZ]”
2007	Agency Appendix G	P 557	Environmental Risk Management Authority Reassessment of 1080	“the Agency considers that the relative contributions of possums and other wildlife (particularly ferrets) to Tb infection of cattle and deer herds are not clearly defined at this time”
