Long-term data sets are needed to understand what causes changes in species communities. Odonata communities provide a variety of ecosystem services, for example being biological indicators in freshwater environment to indicate the water quality. Therefore, it is important to understand what is contributing to the species turnover that occurring in lakes on the west coast of Sweden, Halland. We collected and obtained long data sets from 16 lakes in Halland during 2002 to 2022 has been collected and analyzed. Our result shows that the colonization rate is more abundant than the disappearance rate and that there is an ongoing species turnover, where more generalists inhabit the chosen lakes. Due to increased temperature and precipitation as a result of climate change, but also anthropogenic factors, southern species move more northwards. Another result due to climate change is changes in habitat structures. This is some of the reasons that contribute to species turnover in the lakes in Halland. Another driver can be how well species adapt to change overall. In this report we have contributed with new environmental data from 2022, but also long-term data sets, which is highly recommended to use for future research to understand species turnover in Odonata communities and why species are moving northwards.
