following described invasive species have been known to have harmful effects on the islands' vegetation and native species. Invasive house mice on these islands have adapted to be 50% larger than average house mice. They are thought to have been accidentally introduced by 19th century seal hunters who would dock on the islands. These mice have adapted by consuming sea bird eggs and chicks (as they nest on the ground). Gathering at night in groups of 9 or 10, the mice gather at the bird's nest to feast. With no natural predators, the invasive mice population is able to expand by producing new generations twice a year. In order to prevent the growth of the invasive mice population and extinction of the Albatross bird species, a 2019 Gough Island mouse eradication project was announced (Grundy, 2018). The RSPB and Tristan da Cunha Government have partnered to spread cereal pellets with rodenticide bait across Gough Island, in hopes to eradicate the invasive mice population. The goal of this operation is to restore Tristan da Cunha back to its natural state, ensuring it will still be one of the world's most important seabird nesting sites.
