All soils are carbon-rich soils and deep peat T70 T1 CLASS 2 The vegetation cover is dominated by T2 priority peatland habitats. All soils are carbon-rich soil and deep peat T4 CLASS 3 Dominant vegetation cover is not priority T6 peatland habitat but is associated with wet and T61 acidic type. Occasional peatland habitats can be T56 T8 found. Most soils are carbon-rich soils, with some areas of deep peat T57 T52 T10 T9 CLASS 4 Area unlikely to be associated with T50 peatland habitats or wet and acidic type. Area T11 unlikely to include carbon-rich soils T49 T47 T13 CLASS 5 Soil information takes precedence over T15 vegetation data. No peatland habitat recorded. May T17 also show bare soil. All soils are carbon-rich soil T46 T45 and deep peat T19 T18 Mineral soils - Peatland habitats are not typically T29 T20 found on such soils T41 T42 Non-soil (i.e. loch, built up area, rock and scree) T22 T24 T30 T39 T43 Scale 1:50,000 @ A3 T26 Km T35 T36 T33 T28 0 1 2 Figure 10.3 Peatland Classification Strathy South Wind Farm EIAR 2020 © Crown copyright and database rights 2020 Ordnance Survey 0100031673 SiteBoundary Turbines Superficial Deposits Peat Alluvium – Clay, Silt, SandGraveland Silt, Clay, –Alluvium Alluvial Fan Deposits - Gravel, Sand, Silt andSiltFanDepositsSand, Gravel, Alluvial - Clay River Terrace Deposits RiverTerrace (Undifferentiated)– G ravel, SandSiltand Gravel, LacustrineDeposits SandandSilt Clay, - G laciofluvial DepositsSandSiltand Glaciofluvial Gravel, - Hummocky(Moundy)Deposits Glacial – Diamicton,SandGraveland Hummocky(Moundy)Deposits Glacial Sand,– G ravel and Bouldersand Gravel NotBedrockShallowbeMappedtoLikely - T69 T72 T70 T1 T2 T4 T6 T61 T56 T8 T57 T52 T10 T9 T50 T11 T49 T47 T13 T15 T17 T46 T45 T19 T18 T29 T20 T41 T42 T22 T24 T30 T39 T43 Scale 1:50,000 @ A3 T26 Km T35 T36 T33 T28 0 1 2 Figure 10.4 Superficial Geology Strathy South Wind Farm EIAR 2020 Contains BGS Hydrogeological Maps of Scotland Data.
