Fox R, Dennis EB, Purdy KM, Middlebrook I, Roy DB, Noble DG, Botham MS & Bourn NAD (2023) The State of the UK’s Butterflies 2022. Butterfly Conservation, Wareham, UK. The “State of UK Butterflies 2022” report. This looks at the incredible range of data collected on butterflies in the UK up to 2019. Headline findings include:
Butterfly Conservation report reveals 42% decline in distribution of 58 native species since 1976.
The distribution of 58 native species has fallen by 42% as butterflies disappear from cities, fields and woods. Those that are only found in particular habitats, such as wetlands or chalk grassland, have fared even worse, declining in distribution by 68%. Scientists for Butterfly Conservation, which produced its State of the UK’s Butterflies 2022 report from nearly 23m butterfly records, said there needed to be a “massive step-change” to reverse what it described as disastrous declines in insect populations. The report shows that many of the most endangered species have been revived by targeted conservation action or successfully reintroduced in specific places, but butterflies and other flying insects continue to vanish from much of Britain. |
