-133-Environmen tzones .The Tocher soilscape group occurs in the montane and subalpine vegetativ eT01 Map Unit (Cumulic Regosols )This map unit is characterized by Regosolic soils which are found on calcareous ,medium textured till . The soils have loam to silt loam textures and are well drained ,except for those in the Mount Hurd area which are moderately well drained . Thi smap unit occurs on the extremely sloping (greater than 60%) cutbanksof the Amiskwi ,Emerald and Otterhead Rivers where soil instability results from steep slopes and under -cuttings at the bases of the slopes by the rivers, and in the Mount Hurd area where th esoil instability results from excess soil moisture from snowmelt in spring and earl ysummer . Soil slump and soil flow scars, as well as curved trees indicative of soi lcreep, are common on this map unit .Table 49 .
