Comment:

Swanpool & Furnace Grove consists of a canopy of mature standards and relict coppiced trees. Ash Fraxinus excelsior, Lime Tilia sp. Alder Alnus glutinosa and Silver birch Betula pendula are frequent mature trees. Smaller amounts of Sycamore Acer pseudoplatanus, Cherry Prunus sp., Field maple Acer campestre, Horse chestnut Aesculus hippocastanum and Yew Taxus baccata are also present. Both W7 and W8 types of woodland are present. The Sycamore is not an acceptable naturalised species on this site. The shrub layer includes Hazel Corylus avellanus, Wych elm Ulmus glabra, Goat willow Salix caprea and Hawthorn Crataegus sp. Recent management includes a small amount of tree planting including species such as Oak and Ash. In Unit 2 there are netted coppiced areas dating from 2006 -07. A power line runs through Unit 2. The ground layer appears diverse and is mostly typical of W8 woodland with several sub-communities. There is high cover of Ramsons Allium ursinum, Dog’s mercury Mercurialis perennis, Bluebell Hyacinthoides non-scripta and areas of Wood anemone Anemone nemoralis. Other ground flora species include Yellow archangel Galeobdolon luteum, Pignut Conopodium majus, Wood spurge Euphorbia amygdaloides, Herb Paris Paris quadrifolia and both Common spotted orchid Dactylorhiza fuchsia and Greater butterfly orchid Plantanthera chlorantha.There are a diversity of ferns and sedges including Hart’s tounge fern Asplenium scolopendrium and Pendulous sedge Carex pendula. Open space is generally limited in extent to small glades. Fallen dead wood is common but there is less standing dead wood. There are no veteran/ancient trees. The deer browsing level is high and widespread and evident on shrubs and saplings and is limiting regeneration. A wild boar with 3 piglets was also seen during the survey. This unit can be considered as unfavourable due to levels of deer browsing. Some deer control needs to be instigated to encourage regeneration of saplings and young trees. Further coppicing is unlikely to be beneficial until deer grazing pressure has been reduced but more permanent open space should be considered. The impact of wild boar through rooting damage should be monitored. Levels of standing deadwood and veteran trees could aim to be increased through identifying future candidates. Sycamores should be removed at sapling stage.
