DSC_6045

A recently published study reveals that British butterfly populations are in decline at a rate of 45% in rural areas and 69% in urban areas.

The study published by Ecological Indicators states these as its highlights –

  • Urban abundance trends were negative for all 28 UK butterfly species considered.
  • Trends were more negative in urban versus rural areas for 25/28 species.
  • Declines in composite abundance were significantly more negative for urban areas.
  • Urban populations generally showed earlier emergence and longer flight periods.
  • Indicators are vital for monitoring populations pressurised by urbanisation.
