Wren's Nest National Nature Reserve

Recommended by Visit England Logo
Overview
The fossils found in the 400 million-year-old limestone of the former quarry of Wren’s Nest NNR at Dudley have made it an internationally important geological site. The most famous is the trilobite known as the ‘Dudley Bug’, which is used as the centrepiece of the town’s coat-of-arms. Over 700 types of fossil have been found at Wren’s Nest, 186 of which were first discovered and described here and 86 are found nowhere else on Earth. The limestone grasslands of Wren’s Nest are rich in wildflowers, and there are fine displays of small scabious, milkwort, quaking grass and hoary plantain, plus common spotted, bee and pyramidal orchids. The reserve supports 10 different kinds of butterfly, and you might see red admirals, skippers and small tortoiseshells, plus bumble bees, hoverflies and a variety of beetles. In winter, long-tailed tits, blue tits and great tits move through the woodlands, while redwings and fieldfares are seen in the winter. In late spring, the woodland on Mons Hill rings with the territorial song of wren, blackbird, robin, chiffchaff, great tit and willow warbler.
Location
Wrens Hill Road, DUDLEY, DY1 3SB
About the area
