Drostre Wood is a small mixed deciduous woodland containing oak and birch. Below the canopy of the tallest trees there is a wide range of smaller tree species including aspen, elder, yew, hawthorn, blackthorn and rowan, with shrubs such as holly and honeysuckle.
This small nature reserve, which gives excellent views of the Brecon Beacons, is a section of the former Brecon to Merthyr railway line. Originally built as the Brecon to Hay-on-Wye tramroad, it became a railway in 1864. The line closed in 1964 and became a nature reserve in 1980.
The woodland beyond contains a seasonal pond that dries up in summer.
The reserve annually hosts many species of woodland birds such as treecreeper, goldcrest and bullfinch while summer migrants include chiffchaff, blackcap, spotted flycatcher and redstart. The meadow is home to many interesting moths and other insects and a species list of all flora and fauna is available.
Much work since 2017 has been carried out at the reserve to increase its potential to encourage a more diverse flora and fauna and access to the reserve will also be easier in 2019.
A beautiful area of ancient woodland and unusually a registered common that slopes down to the banks of the Nant Bran.
This is a lovely place to come for a peaceful woodland walk with just the sound of the Nant Bran below you and the woodland birds above you.
