Dragonflies are spreading farther North Britain and Ireland as a result of climate change, According to a new report.
Due to factors such as pollution and habitat loss, the decrease in insect population has attracted people’s attention.
The Dragonfly Nation Study in 2021 also found that since 1970, the distribution of more than 40% of species has increased, while only about 10% of species have decreased.
Several species of dragonflies have reached the British Isles from southern Europe for the first time since 1995, and at least two species have returned after a long absence.
protect Official Eleanor Colver said that the data cannot accurately indicate whether the number of dragonflies or the total number of dragonflies has increased.
She said: “The use of pesticides and other factors [reducing their flying insect prey], Water pollution and habitat loss continue to threaten the health of dragonfly populations within the existing range of species. “
However, the data has been able to map their location.
The report’s co-editor Dave Smallshire said: “The increase in many species, if not all, can be attributed to climate warming and more or better wetland habitats, such as ponds, The number of lakes and gravels has increased. Pits and reservoirs in recent decades.
“The overwhelming message is that global climate change-in the case of the United Kingdom and Ireland-significant warming may have an overwhelming effect on many of these changes.”
The report integrates 1.4 million records from 17,000 loggers collected since 1970 and evaluated 46 species of damselfly. U.K And Ireland.
However, scientists are increasingly worried about the decline of certain insect populations.
