Key messages

A review of 239 bird translocation programmes found 63–67% resulted in establishment of self-sustaining populations.

 

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A review of two years (1987 and 1993) of survey data from 239 bird translocations in North America and Australasia (Wolf et al. 1996) showed 63% of 134 translocations in 1987 and 67% of 105 in 1993 resulted in the establishment of self-sustaining populations. Those translocations involving larger numbers of individuals, translocations of native game species (rather than threatened species), and translocations into the core (rather than the periphery) of the species’ historical range were most likely to establish self-sustaining populations.
