It is too cold and too wet.
We know the Netherlands as it is now but our country used to be the only unreliable flooding water.
All turtles have one thing in common.And that is that they all have to come to land to dig a nest to hatch their offspring. They need a dry wam piece of sand with a low water level. And that’s kinda tricky here.
The sex of some egg grazing animals is also determined by the temperature that the eggs have had.So in the cold Netherlands too many eggs would hatch from the cold sex.
Cold-blooded animals cannot survive the winter well, and then if you do not have hibernation, it is very quickly difficult to survive.
Nowadays there are plenty of turtles and paces that survive in the Netherlands in the cities.Because it stays warmer in the winter and AR more warm places to hibernate. So there will be change. Even though they remain exotic we’ll have to accept that we will soon have turtles as lower animals.
” The European Swamp Turtle is the only turtle species that recently occurred in the wild in the Netherlands but nowadays it is extinct . The species may have disappeared due to hunting because marsh turtles were once eaten. From medieval sources it is well-known that the animals were offered much on markets. Almost a century ago the species would still occur in southern Limburg, according to the book Fauna of the Netherlands by Van Kampen and Heimans from 1927 the distribution in Limburg was described as scattered, but rare, in south-Limburg, especially in the area of the Geleen. ” European Swamp Turtle-Wikipedia
The source below gives interesting information, but the distribution card is very incomplete.Under the map of the Atlas of reptiles of Europe.
The huge gorge between the Loire and the Elbe can be explained very locally by mountains.
For the rest it is nothing more than the action of the Terminator of Fauna Homo sapiens.Direct eradication (see quote above) or indirectly: Mass destruction of biotopes (from the point of view of the surface is nothing equal to agriculture).
- Humidity: How can a species of which life largely lives in the water not support this?
Even in the Mediterranean, the micro-climate that flushes through with water and swamps is not completely dry;
I have a personal experience of both. Just hibernate to a depth that is sufficient to be frost-free.
The northern border of the European swamp Turtle is determined by the shortening of the period warm enough for the incubation of eggs, shallow in the ground.The animals Hatthrown could live far further north. It would be enough for them to be buried longer in the ground to hibernate.
All reptile species that reach high latitudes and/or heights keep the eggs in the female genital organ until they hatch.This allows the incubation to be spread over two summers: the embryos in the eggs in the female wintering freeze freely.
The use of incorrect terms is never neutral.As an American paleontologist specializing in this theme has written, the species do not disappear if they are not killed, or by the fall of an aerolithium, a climatic eruption, the arrival of other species in their geographic area etc., But for centuries, mainly the direct or indirect action of our own kind. Two very different implicit information on the notion and conclusions to be drawnfrom it: the European Swamp turtle is the wild in the Netherlands:
- is extinct: the verb even strongly suggests an Endogen process.
In any case, we can only observe a fact that does not depend more on us than the variations of sun spots. It is ethically very comfortable…
Our ancestors may be excusable, but they are nevertheless materially responsible. Our own responsibility is to study the possibility of recovering this destruction more or less fully and taking action. In France we started in areas where the species had been eradicated, for example in a large lake of Savoy.
Demographical conservation and restoration, with or without reintroduction
For a long time it was thought that many populations had been destroyed because they needed very natural biotopes, very little changed by humans.Well no: Our swamp turtle is ecologically highly adaptable, to secondary arms and neglected mountain streams, as well as water biotopes made by humans. The populations were eradicated, even if there were still acceptable biotopes, because they were massively caught to be eaten and later sold as aquarium animals.
In which their legal protection is respected, the main threats are:
- Woody Development shading the laying areas;
- the Traffic on roads between the aquatic biotopes and the Moorings: There may be hundreds of meters between the two.
This requires fairly simple but decisive measures for habitat management.
Rarer: well-meaning but uninformed people, who return these poor turtles to the pond, so far from the water lost.While they were females going to lay eggs. The solution: information.
The Beaver Cornerstone of biodiversity in certain habitats also for the benefit of the turtle:
- Sunny places:
- Very attractive everywhere: trunks of cut trees partially or completely in the water fallen;
- Streams embedded in riparian forests: local openings of the forest cover;
- creation of biotopes : Water bodies on streams, canals through the marshes, Ezv.
