Before this fish ladder was made, there was a 80 centimeter high rapid here. Impossible to pass for fish, except maybe salmon. The new fish ladder consists of eight 10 centimeter high steps; with space in between them for fish to rest to ‘climb’ the next step. This helps at least five fish species which are quite rare in the Netherlands: chub; brook lamprey; burbot; dace; and ide.
Not far from the Berenschot water-mill is an important spawning ground for these species, which they can reach now. Besides fish, also, eg, water beetles and snails use the pass.
This photo from the small lakes north of the Wooldse veen nature reserve shows moss plants. Some people would call this ‘flowering’ moss. However, mosses are ‘primitive’ plants, which have no seeds or flowers, but spores.
FC Trias got its name because it is a fusion of three earlier clubs.
However, the club grounds are also not far from the Winterswijk quarry. Where muschelkalk stone from the Triassic, over 200 million years ago, is mined. The Triassic got its name from its three distinct rock layers. The Dutch word for Triassic is Trias. In the Winterswijk quarry, recently, a Triassic beetle was discovered; and,earlier, Triassic marine reptiles.
This photo shows cottongrass in Wooldse veen nature reserve, south of Winterswijk, near the Dutch-German border. We went there on 29 April 2017; the day after 28 April.
In 1932, a local businessman started the quarry. Regularly, there were excursions by geologists and paleontologists, to find ancient rocks and ancient fossils.
Now, Belgian multinational corporation Sibelco owns the quarry. The local geological society is no longer admitted for excursions.
There is a short footpath to a part of the quarry where there is no commercial quarrying; and where an eagle owl couple, rare birds in the Netherlands, nests.
This video says about itself:
Eagle owl Winterswijk 01/06/2016
9 September 2016
These young, almost fully grown eagle owls showed well at the old quarry in Winterswijk, The Netherlands. They were quite active in broad daylight. At the end of the movie one of the chicks takes on a beautiful “defending my territory” pose to scare off a common buzzard.
We did not see the eagle owls. We did hear a song thrush sing. And we saw a willow warbler sing on as bush.
A bit further: a chiffchaff singing. A buzzard flies.
