Detailed Description

The Skiddaw association is extensive in Cumbria, on the northern and north-western hills of the Lake District, on high land above the upper Lune Valley and on Black Combe, in the extreme south-west. It is also found in small areas in north Wales. It is generally above 450 m O.D. on moderate to steep slopes, craggy in places, underlain by Palaeozoic slaty mudstone and siltstone. The highest land is on Skiddaw at over 915 m O.D. All districts are cold, wet and exposed. Humic rankers, Skiddaw series, predominate but on gentler slopes there are ironpan stagnopodzols, Hiraethog series, and raw oligo-fibrous peat soils, Winter Hill series. The association includes areas of deeper soils of the Manod, Hafren and Hiraethog series. In hillside flushes, the Wilcocks series and occasionally the Longmoss series are found


Soil Water Regime

The shallow Skiddaw soils absorb little winter rain and in the wet climate lie waterlogged for much of the winter. Shallowness and small available water capacity make the main soils droughty in dry weather, however. Although ironpan stagnopodzols are deeper, the ironpan and other layers reduce percolation. Deep peat has formed in very wet conditions where run-off is slow.

Cropping and Land Use

The land has little agricultural value because of the shallow wet soils and rainy climate. Most is under Nardus, grazed by a few sheep, but heather is becoming dominant on the Hiraethog series. Although the vegetation is of moderate grazing value its improvement would not be economic because of remoteness, persistent wetness, which generally cannot be alleviated, and the risk of soil poaching. Some areas are used for forestry but the shallow rooting depth causes vulnerability to windthrow. Most of the land is good walking country and is included in the Snowdonia National Park.
