When undertaking an appropriate assessment of impacts at a site, all features of European importance (both primary and non-primary) need to be considered.

|91A0 Old sessile oak woods with Ilex and Blechnum in the British Isles|
|Glen Shira is located at the northern end of a typical U-shaped valley on a south-east – north-west axis, rising from sea level to above 500 m. The site contains habitat representative of old sessile oak woods with Ilex and Blechnum. The site comprises two distinct blocks of oak wood, separated by the River Shira and associated areas of open and grazed ground which are excluded from the site. The orientation of the valley means that the woodland is situated on both north-west and south-east facing slopes, which has encouraged the development of greater diversity. The qualifying oakwood habitat in the western part of the site is interspersed with areas of non-qualifying alder–ash woodland and patches of open ground where regeneration is occurring. The eastern block consists almost entirely of qualifying old sessile oak wood, mainly oak-dominated, with alder Alnus glutinosa, ash Fraxinus excelsior and hazel Corylus avellana also present. The main NVC types representing old sessile oak woods across the site are W11 and W17. The woods support an outstanding assemblage of bryophytes, including both oceanic ‘Atlantic’ types and calcicolous species. Glen Shira as a whole is considered to be one of the richest woodland bryophyte sites in Scotland, with 128 species recorded within the western block alone, of which 27 are Atlantic species.|
