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 wildflower meadow has always been managed traditionally with grazing by cattle or ponies from spring to autumn. This kind of rough, damp grassland is known in Wales as Rhos pasture and is becoming rare. Please keep dogs on a lead as skylarks often nest within the rough grass.
