ASSESSING THE POTENTIAL RISK OF IMPACTS BY FOUR NON-NATIVE BIRDS SPECIES ON BIODIVERSITY IN IRAQ

Abstract

Invasive bird species pose a significant threat to biodiversity and ecosystems worldwide. In Iraq, non-native avifaunal species are increasing, leading to various environmental challenges. This study aims to evaluate the risk of invasiveness and potential impacts of four non-native, extant bird species on Iraq's biodiversity under both current and predicted climate change conditions. Surveys were conducted in November 2023 and 2024 on four non-native bird species present in local animal markets throughout Iraq. The study sites included the provinces of Baghdad, Basra, and Erbil, which harbour commercial centres and the largest local animal markets in the country for trading non-native species. In this study, the target species for screening were selected after an extensive literature search and review of non-native bird species in Iraq. Using the Terrestrial Animal Species Invasiveness Screening Kit (TAS-ISK), this study evaluated the potential risk of invasiveness in Iraq of four of these non-native bird species: bank myna Acridotheres ginginianus Latham, 1790, common myna Acridotheres tristis (Linnaeus, 1766), Namaqua dove Oena capensis (Linnaeus, 1766), and rose-ringed parakeet Psittacula krameri (Scopoli, 1769). The findings revealed that for commercial, environmental, and species or population nuisance traits, A. tristis and P. krameri pose a high risk of invasiveness, whereas A. ginginianus and O. capensis pose a medium risk. The present results highlight the need to include these species in decision-making and management programmes to mitigate their impacts on Iraq's biodiversity.
