Post-release monitoring
Monitoring methods
Barratt et al. (2006) recently reviewed post-release monitoring research for biological control agents and provided guidelines. The guidelines are based on previously published information and case studies detailed in the same chapter. In practical terms, a logical method of evaluating non-target effects is to combine this with measuring target effects using similar methods as far as possible. This can be appropriate when target and potential non-target hosts are in the same environment: for example, in early post-release studies and in cases where the biological control agent is very immobile; however, impacts often extend beyond the target host environment, requiring a different approach.
These guidelines for post-release monitoring are taken from Barratt et al. (2006), and reproduced here with permission from CABI, Wallingford, UK.
