Alder groves
|
| |
Alder groves tend
to grow naturally in alluvial deposits on the edge of
streams. Higher up the valleys they can be found growing
on peat moss (a moss that loves very acid, wet soils),
while downstream they are often intermingled with ash-woods
or alluvial forests.
A number of remarkable plants grow in these marshy forests
such as the Bog Arum (Calla palustris), the Marsh
Fern (Thelypteris palustris), Common Horsetail and numerous
varieties of sedge.

The Marsh Marigold (Caltha palustris), a highly
pervasive plant gives large splashes of yellow in the
valley bottoms.
