Knocksink Wood Nature Reserve
Some of the valley slopes are dominated by sessile oak, while other areas are characterised by mixed woodland. Notable features of the slopes are the frequent and extensive springs and seepage areas within the woodland. These petrifying springs are listed as a priority habitat in the EU Habitats Directive. The site has one of the most diverse woodland invertebrate faunas in Ireland, incorporating wet woodland organisms threatened internationally within the EU. There is an educational centre within the site.
Vale of Clara Nature Reserve
A large area of fragmented oak-wood. It contains the largest area of semi-natural woodland in Co. Wicklow and is potentially one of the largest stands of native hardwoods in the country. The area has been at least partially under woodland since the Ice Age. The oak-woods are also of high scenic value.
