The islands are one of the most important breeding colonies for seabirds in Europe, with around 10 per cent of UK puffins and 7 per cent of UK razorbills breeding here every year. The islands recently completed the Seabird Recovery Project (2014-2018), which now offers a great prospect for seabirds to establish new colonies, such as Manx shearwaters and storm petrels. Over the next few years, the abundance and diversity of the land bird populations will be investigated to observe their response to the changes. Monitoring of the flora and invertebrate communities will also take place to see how these communities adapt.
