7 - Conclusion

Summary

The aim of this book, as described in Chapter 1, was to review critically the literature on the range of analyses used in vertebrate pest research. I will now briefly summarise the results.

There is a great range of analyses that have been used. The analyses have been used to estimate the level and variation of pest damage and response to control. The three sets of analyses described in this book – statistical, economic and mathematical modelling – have received differing use in research on vertebrate pests. In order of decreasing use the analyses appear to be statistical, modelling and economic. That is surprising as the fundamental reason for the pest status of most animals is their economic impact. There is a great need for closer liaison between biologists and economists to overcome this apparent difference. This could be achieved by involving an economist in a study at the same times as involving a biometrician – project design, analysis and writing-up. The statistical basis of analysis of vertebrate pest control may appear to be emphasised in this book. That should not be interpreted as a signal of my preferences. I believe all three analyses should receive more study.

There have been few detailed comparisons of particular methods within each of the three sets of analyses. For example, predation can be estimated by one or more methods, as described in Chapter 2.
