Last Flowerings in Britain and Ireland?

The Plant Atlas 2020 has been produced, after 20 years of Botanical study in the UK and Ireland (https://www.theguardian.com/environment/2023/mar/08/half-of-britain-and-irelands-native-plants-have-declined-over-20-years-study). This Plant Atlas reveals that, over the last 20 years, around 50% of Britain and Ireland's plant species have declined. Native species and Archaeophytes (Ancient introductions) have shown the biggest reductions. Non-native species are now actually more numerous, in the wild, than either of these two categories. Agricultural practises are the main reason for the declines. Farming has caused habitat degradation, including nitrogen enrichment of soils. Grazing pressures and the draining of wetland areas have also disadvantaged certain plant species. Climate change must also be influencing geographical distribution of particular plants. These changes in flora will, of course, also be having powerful impacts on the distributions of animal species (especially insect pollinators).
