Locals Only?

Although some species, such as the Bee orchid, have done well recently, other 'native' UK species including the Puffin and the Arctic tern are in decline (https://www.theguardian.com/environment/2019/dec/27/uk-weather-attracts-migrant-species-but-threatens-native-ones). These effects have been linked to changes in the weather patterns that also bring in species from abroad, such as the Long-tailed blue butterfly. Although some people may appreciate the increased diversity, not all species can deal with environmental changes that are so rapid and widespread.
