89Soil Map Unit 7The moderately coarse textured soils of Map Unit 7occur onsteeply to very steeply sloping land surfaces where there appears tobe considerable soil movement which isdisrupting and impeding soilprofile development .Classification :These soils are classified as Orthic and Cumulic Regosol .Profiles consist of a deep Ah horizon often apparently cumulic innature, directly overlying the C horizon .Associated Map Units :The Regosols of Map Unit 7are often closely associated andcomplexed in mapping with the Podzols of Map Unit 9 .The Regosols occurunder herbaceous plant communities in open areas within the forestcommunity and the Podzols under tree stands in these areas .The soilsof Map Unit 2 are often closely related, geographically and genetically,to Map Unit 7 soils ; however, the former have B horizons .Vegetation :Plant communities ofthis map unit are made up of mixedherbaceous stands, often occurring as open areas in discontinuous forest .Typical species include Senecio triangularis , Ligusticum canbyi andErigeron peregrinus with Abies lasiocarpa ,Rhododendron albiflorum andVaccinium membranaceum surrounding and occasionally covering the areas .Pedon Description:Described by : L .
