The Central Lowlands extend across Scotland with the Grampian Mountains to the
north, fringed by the Highland Boundary Fault stretching between Stonehaven
and Helensburgh and the hills of the Southern Uplands to the south separated
by the Southern Uplands Fault. Whereas the greater part of the region lies
below about 175 metres many areas exceed 300 metres and the highest parts
reach to nearly 600 metres culminating within isolated peaks within the
Campsie and Ochil Hills.
The regional relief has been determined basically by differential erosion of
the rock types with the resistant igneous rocks forming hill masses and the
softer sedimentary rocks form broad, undulating plains with major river
valleys. The landscape has been modified, however, by the effects of three
different phases of glaciation followed by oscillations in relative land and
sea levels and these have resulted in the formation of different soil parent
materials ranging from glacial till deposits to late and post-glacial raised
beaches with sands, gravels, silts and clays all present. Within the hill
areas, drift and shallow drift deposits are widespread, the latter associated
with zones of outcropping rock.
Simplified landforms of the
eastern Central Lowlands - deep brown forest soils are widespread on
the till plain with imperfectly draining variants and gleys in the
intervening hollows. Podzols, including peaty podzols, characterise the
hill areas with rankers and lithosols associated with areas of rock
outcrop.
Simplified landforms of the
western Central Lowlands Mixed glacial tills, often with relatively fine
textures, are widespread with a high proportion of surface-water gley
soils. Brown forest soils are restricted to the highest ground and peat
mosses occupy the larger hollows. |

Agriculture is widespread but
with considerable human influence. There has also been extensive planting
of plantation woodland, both coniferous (for commercial forestry) and
deciduous (for amenity planting). Widespread industrial use and urban
development have altered the landscape; the vast conurbation of Glasgow and
its satellite towns are intermingled with industrial sites. Previous
mining, both coal and oil shale, has also left an impact with derelict
land and reinstated land a direct legacy of such development. Recent
interest in reclamation and restoration has addressed such industrial
development.
