THE VEGETATION.
57
The firwoods of the region are generally mixed firwoods characterized by
the same plant» as those of the preceding region, to which several new species are
added. The firwoods have by heavy cutting often been transformed into pastures
with sparsely growing firtrees and birch, and more grass and herbs than in
normal firwoods. The oakwoods are made up of oak interspersed with ash, elm, and
others, and a lower growth of hazel, hawthorn, wild rose, blackthorn, and others,
with plenty of herbs and grasses between the bushes. The leaf-tree meadows
are marked by their groups of diverse leaf-trees, as oak, ash, maple, lime, aspen,
birch, Swedish beam, bushes in thin groups made up of hazel, hawthorn,
blackthorn, wild rose, and others, with a luxuriant surface covering of herbs and grasses.
The herb-filled firwoods are peculiar by the absence of cowberries, bilberries,
and wavy hair-grass and by their wealth of herbs and grasses. By devastation
of woods, wide districts in Bohuslftn and Vestergötland are transformed to heaths.
The peat-bogs are of about the same character as those in the southern part of
the fiiwood region. The sedge marshes are marked by a thick carpet of sedges
with herbs strewn in, with or without a bottom-covering of Amblystegium.
In the Mining districts of Central Sweden.
The lakes are often marked by a well-developed, high grass-belt of the
common reed (Phragmites communis Trin.), common bulrush (Scirpus lacustris
L.), cat’s tail (Typha angustifolia L.), and others. Within this belt a floating
leaf-belt appears, made up of water-lilies (Nymphæa, Nuphar), pond-weed
(Pota-mogeton natans L.), and others, after which other plants continue, of which only
the flowers are above water or else altogether below the surface. The rocks
appear as in the firwood region.
