Our piece of woodland, Ninewells has been classified as W16 but I am not so sure. Here is a description of W16
Lowland’ acid oak woods (W16)
Because of climatic differences woodland types in the south and east of the country differ from those on equivalent upland soils.
Thus on very acid soils in the south and east oak and birch still predominate (W16), but because of the warmer, and particular dryer conditions the moss carpet is virtually absent, or if present relatively species-poor. The ground flora may be more or less restricted to bracken, wavy hair grass, bilberry or heather. Such heathy soils are generally unproductive and often left as common grazing. Hence this type is not uncommon in wood-pastures such as at Sherwood Forest.
I have not found Wavy Hair grass in Ninewells, at least not in my bit of it, there is however quite a lot of ferns and mosses and Bilbery also some Bluebell and Wood anemone. So I think it is more like W11, here is a description of W11
Western oakwoods (W11,17)
Moving from the central and eastern highlands across to the west coast of Argyll and Lochaber oak replaces pine as the main tree in native woods. The similarity in the soils and the overriding effect of the high rainfall mean that there is much in common between these west Highland woods, those in Cumbria and North Wales and those on the north coast of Cornwall, in the Exmoor Coombes or fringes of Dartmoor.
In the Peterken Stand Type system these woods were separated into those whereQuercus robur dominant and those where the main oak was Q petraea. Sessile oak is the more common but Q robur does sometime occur – for example in Wistman’s Wood on Dartmoor, around Loch Lomond and at Loch a Mhuillin in Sutherland – one of the most northerly oak woods in Britain.
This oak species distinction is not made in NVC: rather the split is made on the nature of the ground flora: in the wettest conditions and on the thinnest, acid, soils bryophytes predominant (W17). On the rocks or tree bases there is an incredible variety of moss & liverwort species. Since these also occur in some of the cleanest air zones they are often rich in lichens even on relatively small trees; they are also particularly associated with wood warbler, pied flycatcher and redstart.
Where the soils are deeper grasses, bluebell and bramble become more common although there may be little change in the tree and shrub layer (i.e. still mainly oak and birch) (W11).

As you can see it is quite complex and could be described as a bit nerdy but also I think quite interesting. If you wish you can use the links to determine what your patch of woodland is.
