When Nature Wins ...


A complete little angler

The Skjern Å Salmon
Natura 2000, North Europe's biggest nature restoration by Skjern Å in West Jutland has already brought fine results. Plants, which were almost extinct have come back for good, and the bird and animal life is thriving. It has especially been good for the birds. 136 different birds' species were counted in 1994 , and 255 counted in 2006.

At a point it seemed that the original Skjern-Å salmon was extinct, but old scale samples from the 1930s and 1950s showed via dna-analysis that the salmon from then and now is genetic identical. In 1984 were only caught 5 salmons in Skjern Å - this year the anglers have set a record with 301 salmons. And the salmon is bigger now.

It has been amazing how nature establishes itself, when a big area is taken in and made into a nature area. There is a richness of species now; the positive effect has arrived much faster than hoped for, and the successfull nature restoration by Skjern Å could very well be a role model for other nature projects in the country.



What have we caught?

Those boys might have high hopes for their future as a complete angler.......

The Sea Trout
It's high season for the sea trout in November and December. It has now lived in the sea for about 3-4 years and comes back to its childhood's fresh waters to continue the family. It has reached a weight of 4-5 kilos, but the growth might be colossal. Sea trouts of 10-20 kilos are caught by anglers every year.

The sea trout is special because it spends its life in salt water in the sea - other trouts, like the brown trout, stay in fresh water through their life. But they are all of the same species, Salmon trutta trutta - whether they live in the sea, in the lake or in the river.

I like the harvesting of the sea trout or attempt to do so.

Come-back stories are treasures. Especially when scientists, naturalists and ordinary people work together. And, like Jack said, harvesting the sea trout is a good idea.

Hej Kittie and Jack!
You are both so nice to visit and comment on the story about the sea trout - and you're right. And every story about doing something good for nature is a comforting thought in this world.
Cheers

The sun is shining today!

It is encouraging to know nature can come back if given a chance. I love the photos of the children and their nets, escpecially that last one. It reminds me of a Hummel figurine.

I had to look for this Hummel figurine, and the one who is on Wikipedia right now reminds very much about that little guy here. That's funny. I didn't know these figurines. I learn something new every day!

Children are so wonderful. They don't notice you, and they are completely spontaneous and natural.
