The large expanse of open, uninterrupted grassland on the Rowley Hills situated between Portway Hill and the Birmingham New Road, known as Portway Hill Open Space, is currently one of the best sites in the West Midlands for Marbled White and Small Heath butterflies. Mike Poulton has been studying populations of these two butterfly species for the past five years and has produced a short report summarising his findings so far. The overall picture is a mixed one, with Marbled Whites thriving but Small Heaths declining. Click here to read the full report.
