Ardley Quarry

Ardley Quarry is a rich mix of different habitats including scrub, woodland and grassland. Warm and sheltered, the site is especially good for butterflies, and has thriving colonies of grizzled skippers, dingy skippers and green hairstreaks.

Historic site

This old quarry and nearby railway cutting have geological features of national importance - as well as abundant wildlife. The layered bare limestone rock faces give a fascinating insight into the site's Jurassic past (more than 160 million years ago). Medieval earthworks show Ardley Quarry's more recent historical interest (from just a few centuries ago) as well.

A rich mix

Scrub, woodland and rough grassland make up the diverse array of habitats. Several seasonal ponds (which dry out in summer) provide breeding places for frogs and great crested newts. Enjoy the first signs of spring with cowslips, primroses, blue bugle flowers and a carpet of violets. In summer, look out for the common spotted orchid and bee orchid.

Butterflies basking

This warm, sheltered site is good for butterflies, which are not deterred by the occasional passing trains. There are good colonies of grizzled skipper, dingy skipper and green hairstreak butterflies, especially near the quarry floor. Marbled white butterflies can be spotted in the taller grassy areas.

Wonders of the woods

As well as the plentiful butterflies all around the site, munjtac deer forage in the woods, and woodland birds nest in the trees. Listen out for long-tailed tits, chiffchaff, willow warbler and bullfinch.
