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 study on Lord Howe Island, Australia, between 1980 and 1983 (Miller & Mullette 1985) found that Lord Howe Island woodhens, Tricholimnas sylvestris, successfully reproduced in a purpose-built breeding centre. In 1980, the only three healthy adult pairs of woodhen were taken into captivity and they produced 66 chicks which were reared in captivity. This study also describes the impact of predator control (see ‘Control mammalian predators on islands’) and release of captive-bred individuals (see ‘Release captive-bred individuals’).
