During the latter half of the 1900s the big natural river deltas on Westland disappeared. Until the 1980s there was still a small, but significant remnant of the original river delta from the Etneelva river, but today most of this, too, is industrial land.
At nesting time you cannot avoid hearing the calls of the curlew or the snipe along the narrow road through the cultural landscape from Rimbareid to Vestbøstad. And on late summer evenings, the intense song of the sedge warbler rings out over the two characteristic tarns in the area.
It is difficult to imagine that a plant can grow at the same place for many thousands of years: Climate and local environment change. Different species grow up and die out. Nonetheless, some plants get established, but don't manage to spread into new areas, because the climate is at the edge of what they can tolerate. Great fen-sedge is just such a plant.
Plants that grow in and beside water have to be prepared for marked and rapid changes in their living conditions. They must be able to tolerate living under water without drowning, and getting totally dried out without whithering. Many swamp plants are well adapted to these kinds of changes.
If you smell a foul smell out in nature, you mustn't immediately think that the reason is cloaca from houses or cabins. The reason can be an entirely natural process that occurs when plants are broken down under special conditions. When there is little oxygen available, hydrogen sulphide can be produced. This is a gas that seeps up from the earth and smells like rotten eggs.
