4 Southampton Common East of the Avenue (2). General description. A large block of semi-natural ak and Holly dominated woodland with associated grassy glades, lawns and rides, situated on the eastern edge of Southampton Common. The site is a SINC and lies immediately adjacent to the Southampton Common SSSI. Management. The site is largely unmanaged apart for some very limited amenity tidying up and mowing of the rides and small lawns. Some old plantation forestry. Communities. (1). [MG7]: Lolium perenne - Plantago major grassland. egularly mown amenity glades and edges, which retain a moderate to patchy canopy of old standard and late pole stage Pedunculate ak. Effectively improved wood pasture. Flora :- ye-grass, Yorkshire-fog, Cock s-foot, Dandelion, Grey Sedge and Common Daisy. (2). [W10]: Quercus robur - Pteridium aquilinum - ubus fruticosus woodland. Canopy :- Shrub layer :- Flora :- (3). Transitional stand. Fairly complete (to moderate) cover of old standard Pedunculate ak with occasional standard and late pole stage Beech. Dense Holly to 10 metres. With occasional regeneration and regrowth of Beech, Hawthorn, English Elm owan and Silver Birch metres, 80%-100%. Ivy, Bramble and Bracken. Small and recently planted block of Field Maple and Silver Birch. (4). [MG7]: Lolium perenne - Plantago major grassland. Largely improved amenity lawns but occasionally becoming more transitional [MG6]: Cynosurus cristatus - Lolium perenne grassland and even [MG5]: Centaurea nigra Cynosurus cristatus grassland locally. (5). [W10]: Quercus robur - Pteridium aquilinum - ubus fruticosus woodland. Similar to (2), but more obviously broken and scrubby. Also largely lacking taller canopy trees. (6). [W10]: Quercus robur - Pteridium aquilinum - ubus fruticosus woodland. Similar to (2), but with moderate to scattered old standard Pedunculate ak, over dense Bramble and Nettle. (7). [W10]: Quercus robur - Pteridium aquilinum - ubus fruticosus woodland. Although now reduced to a strip of pole stage and young standard Silver Birch and Pedunculate ak with locally dense Gorse and Grey Willow, along the drainage line.

5 (8). Plantation. Canopy :- Late pole stage Beech. To 30 metres. (9). [W10]: Quercus robur - Pteridium aquilinum - ubus fruticosus woodland. Canopy :- Shrub layer :- Flora :- Moderate cover of old standard Pedunculate ak, Beech and conifer with frequently quite dense sub-canopy of pole stage and regrowth Silver Birch, Pedunculate ak, Cherry and Sycamore metres, 80%-90%. Patchy with locally dense Holly, Cherry Laurel and Sycamore regeneration with owan and Hawthorn metres, 60%-100%. Ivy and Bramble dominated.
