Sorry, this entry is only available in Deutsch.
Yesterday we took a picture of an cicada which is only a few mm large. Blue coloured ends of the elytrons, otherwise light brown striped. It is not to be found in the internet. Who can give a tip?
We see a bat regularly at dawn. Originally at 4.30 o’clock, now later in the year at half past five and later. It is a large bat. Unfortunately, it did not fly when we installed the infrared camera. Do they see in the infra red?
in diesem Jahr sind wir verspätet: Eine schwere Krankheit hat uns ziemlich blockiert und hemmt noch imer unsere Aktivitäten. Dennoch gibt es einige neue Nachrichten:
- Ganz von allein hat ein Bauern das Gülleverbot im NSG respektiert! Das ist ein wichtiger Fortschritt,weil sich die vielen Hinweise endlich im Kopf eingenistet haben.
- Es hat eine Kreuzotter-/Schlangen-Inverntur im Urseetal stattgefunden, bei der wenigstens 1 Schlange auch gesichtet wurde. Zuvor war Gerrit Müller, der Schlangenbeauftragte für den Hochschwarzwald, schon zu Besuch und war ebenfalls fündig.
- Neben vielen Kleinen Füchsen haben wir schon sehr früh einen Schwalbenschwanz gesehen, Mohrenfalter sind auch schon unterwegs (Erebia meolans) und einige Bläulinge waren auch schon zu beobachten.
- Die Libellen in unserem Teich sind auch schon geschlüft (Azurjungfer, Adonislebelle, Plattbauch, Vierfleck, und Blaugrüne Meerjungfer).
Wir werden weiter berichten.
While we were cross-country skiing we notice along the Urseebach a pair of White-throated Dipppers, the male chittering most delightfully. The two were, however, unsettled by a dog which ran on the path along the brook, the dog, however, was very correctly chained. But how may a small dipper decide whether a running dog is harmful or not?
After photographs of the Common Adder (vipera berus) we have now documented another snake in the Urseetal: The Smooth snake. This snake preferes sunlit habitats we actually find on the northern part of the Urseetal after the devasting “Lothar” storm in 1999. The snake’s presence might force the Fürstenberg’s Forest administration to reconsider the replanting of common spruce in that part of the Urseetal since the Smooth snake is considered endangered and has found entry into the FFH list of the European Union as especially protected.
At 860 m above sea level the finding would normally be fairly high, but in the Black Forest these snakes live up to 1100 m above sea level.
At the 9.August 2012 additional pictures were taken (the aminaml shown here is about 35 t0 40 cm long:
Dear friends of the Urseetal,
The sound-barrier has been broken!
more than 50 different butterflies have been photographed in the Urseetal since 2007 when we started to take pictures. We have prepared a socalled .kmz file which indicates the dimension we found these animals within. If you have installed google-earth you may be able to open it. This map confirms, that we have found all these butterflies within a fairly limited space not more than 3.5 km long and maximally 500 meters wide which amounts to maximally 1.7 square kilometres. Not more. Only part of it is a dedicated natural reserve first installed in the early 1930s and extended to its present size in 1992. For reasons of visibility we have focused on butterflies, but the richness in moths, in locusts, dragonflies as well as in snakes is as remarkable.
How has this richness arisen? There are others which are more competent to talk about that. We are more concerned about ways to maintain this variety. The agriculture here cannot have been so detrimental, otherwise the richness would be much reduced. However, we would like to remind those concerned that whoever is working within the boundary of the natural reserve and the areas along, that there are other considerations in such a precious area than financial success. The natural richness needs to be preserved and the habitat for all the endangered butterflies must be preserved. Even if the Urseetal is within a recreation area the access to and grasp of its resources should be very much restricted. Fertilisation by the local farmers should strictly follow those rules established 1992 when the natural reserve had been enlarged. Wandering is only allowed using the tracks within in the natural reserve. With the newly erected plates indicating the boundaries of the natural reserve people might become more sensitive about where to go and where not.
We are not going to charge local and foreign people for transgression which respect to species conservation and behaviour in a natural reserve, but we would make everybody aware what is correct and what is not. However, if people use their car on forest of field tracks within the natural reserve, if such field tracks are paved with gravel, than we will pass this information to the authorities, and hope that the farmer has to pack away the gravel. We have also informed the forest authorities when endangered species were damaged while trees were chopped in sensitive areas. It is not bad will but mostly missing information and neglect which today threatens the plants and animals in the natural reserve. More sensitivity due to ongoing talk about the natural reserve and our obvious presence while photographing larger and smaller animals and animals therein might be a constant reminder for those work most here.
When you happen to come to Lenzkirch and be our guest in the Urseetalwe would like you to keep in mind that in a sensitive natural reserve, much can be destroyed with a short time which needs long weeks, months or even years to regenerate.
