Key Findings

The UKBMS provides a wealth of information on the trends and status of butterfly species. Some of the key findings from the scheme are:

• Trends over time in the status of individual butterflies .
• Trends over time in the status of trends in groups of species (generalist vs specialist, woodland vs grassland).
• Trends over time in the overall change in phenology.
• Trends over time in the overall changes in abundance.
• Identifying sites at which butterflies are generally performing well or badly.
