Townclose Hills, or Billy Woods as it is commonly known, is a prominent knoll of magnesian limestone surrounded by low-lying arable land.

Townclose Hills comprises a steep-sided grassland plateau with woodland, wildflower meadows, scrub and a disused railway cutting with exposed limestone and shallow, spring-fed pools. The grassland plateau became a SSSI in 1984 as the largest example of a magnesian limestone grassland over 1 hectare in the county. The grassland is important for its diverse assemblage of flora and comes alive in the summer with clustered bellflower, field scabious and orchids. From the grassland plateau a beautiful panoramic view of the surrounding countryside can be enjoyed.

The wood is the most dominant part of the site. Quarried areas of the site support scrub woodland communities of wych elm, sycamore, hawthorn, blackthorn ash with sanicle and the regionally rare ploughman’s spikenard.  As you walk through the reserve, keep your eyes open for butterflies such as gatekeeper, speckled wood and comma and birds such as yellowhammer, fieldfare and lesser spotted woodpecker.

If you fancy a late night stroll, female glow worms can be seen attracting a mate during summer and you may even spot a badger.

Townclose Hills is part of the green corridor in the Lower Aire Valley in Leeds which is managed in partnership between Yorkshire Wildlife Trust and Leeds City Council.
