This dataset curates over 200 records of known non-native species introductions to Antarctica, where introductions are considered to include inadvertent and deliberate introductions to the environment where the specimen/s were not immediately removed. Each record contains information on occurrence status, location coordinates, observation year, estimated survival time and more. The dataset was compiled by Theme 2 of the SCAR Scientific Research Programme Ant-ICON (Integrated Science to inform Antarctic and Southern Ocean Conservation). This project was supported by NERC core funding to the BAS Environment Office and Biodiversity, Evolution, and Adaptation Team, and by the Royal Commission for the Exhibition of 1851.

This dataset contains audio recordings of birds in four woodland plots invaded by the non-native species Rhododendron ponticum or Prunus laurocerasus and non-invaded control plots in the same woodlands. The four locations were in Wales; Nercwys Forest; Penllergare, Swansea; Aberkenfig; and Wye Valley, Cleddon Shoots. Recordings were conducted in hourly intervals in the morning and evening for one or two days in each location, between June and September 2023. The aim of the data collection was to analyse if any differences in the number of bird species and frequency of bird calls could be found between invaded and non-invaded woodland plots. This is the complete dataset. The work was supported by the Natural Environment Research Council (Grant NE/X013332/1).
