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 reserve, once the site of extensive coal mining, is a great example of how nature has reclaimed the landscape. It is a rich mix of wildlflower meadow, rhos pasture and young woodland. It is one of the best sites in Wales for the rare marsh fritillary butterfly.
This reserve is a charming small area of woodland renowned for its floral display.
