Key messages

  • One study evaluated the effects of developing/implementing species recovery plans on reptile populations. This study was in Australia.





  • Conservation status (1 study): One controlled, before-and-after, paired study in Australia found that the chance of a species’ conservation status improving or being stable was similar for those with a recovery plan (including three reptile species) and those without a plan (including three reptile species).

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 controlled, paired species, before-and-after study in 2010 in Australia (Bottrill et al. 2011) found that species with a recovery plan (including 3 reptile species) were not more likely to have improved conservation status compared to species without a plan (including 3 reptile species). The chance of the status of a species being stable or improving was similar for species with a recovery plan (66%) and without a plan (62%). The evaluation assessed species status of 56 species (including 3 reptile species: striped legless lizard Delma impar, Bellinger River Emydura Emydura macquarii signata, Blue Mountain’s water skink Eulamprus leuraensis) with a recovery plan and 67 threatened species (including 3 reptile species: Flinders Ranges worm-lizard Aprasia pseudopulchella, Mary River turtle Elusor macrurus, Krefft’s tiger snake Notechis scutatus ater) without a recovery plan. All species were listed under the Environment Protection Biodiversity Conservation Act and either had an approved single-species plan or were lacking a federal recovery plan.
