You can visit one of the UK's biggest urban nature reserves within the city of Birmingham. The Saltwells Local Nature reserve is a massive 247-acre site in the Dudley area. It was originally planted 200 years ago to cover a landscape scarred by mining. Today the result is a massive wooded area with overgrown cliffs and claypits. If you visit the Saltwells Local Nature Reserve you can see a wide range of wildlife. Enthusiasts have spotted 16 species of dragonfly plus rare orchids and anemones. Saltwells is mostly a broad-leafed wood with old oaks and beech trees forming habitats for rare birds like the treecreeper and the great spotted woodpecker.
