Perryfield Quarry: Introduction

Wed, 20 May 2026 00:00:00 GMT

A giant fossil ammonite sits at the gates - a Titanites, roughly the size of a tractor tire, coiled in stone that is 150 million years old. Walk past it on a July afternoon and you will see the same kind of contradictions everywhere in Perryfield Quarry: chalkhill blues lifting off a knapweed flower next to a working face where masons are cutting blocks for a London building, the disused railway track threading through scrub that hides glow-worms after dark, the Whitbed stone breaking cleanly from a bed it has waited in since the Jurassic. The quarry is still working. The quarry is also a butterfly reserve. Portland has long been a place where industry and ecology share the same fence line.

The silver-studded blue is Perryfield's signature species, with a thriving colony established on the warm limestone of the reserve. Look closely on a bright June day and the small males flutter in shimmering clouds over the low vegetation. Other blues join them through the summer...

Perryfield Quarry: Birds in the Sycamores

Wed, 20 May 2026 00:00:00 GMT

Above the butterflies, the copse of sycamores and the scrub-covered slopes down to the disused railway line form one of the best migrant-bird funnels on the southern Dorset coast. Portland sticks out into the Channel, and migrating birds that find themselves over open water at da...
