When undertaking an appropriate assessment of impacts at a site, all features of European importance (both primary and non-primary) need to be considered.
Annex I habitats that are a primary reason for selection of this site
|91A0 Old sessile oak woods with Ilex and Blechnum in the British Isles|
|Coedydd Aber is the largest continuous area of old sessile oak wood along the north Wales coast, and gives geographic representation of the habitat between the large examples further south in Wales, and those to the north in Cumbria. The main woodland extends along a valley, rising steeply from near sea level. The canopy consists largely of sessile oak Quercus petraea and downy birch Betula pubescens, but there are intricate transitions to ash Fraxinus excelsior woodland and extensive areas of alder Alnus glutinosa woodland. The ground flora is diverse, reflecting complex edaphic and management variations. There is a rich lower-plant flora, including the rare mosses Fissidens rufulus and Philonotis rigida, and the lichens Degelia plumbea and Lobaria amplissima. The site is also important for its breeding bird assemblage.|
