  1. Use legislative regulation to protect wild populations

    A literature review and meta-analysis (Pain et al. 2006) found that protective legislation reduced nest-take (the percentage of nests from which chicks were removed by people) in wild parrots and may increase nest success. Across 20 species-country combinations, medium (involving either national or local protection) and high (involving both) levels of protection significantly reduced nest-take between 4.5 and 50 times compared to low levels of protection (unenforced, ambiguous or absent local or national protection). These results excluded a Nigerian study based on trapper surveys and with 100% nest-take, but included Australian data – Australia being the most developed country in the analysis and with a disproportionate number of studies. If both countries were excluded then medium and high protection resulted in a significant (170%) increase in nest success. However, if all data were included then there was a non-significant increase in nest success.
