Sorry, this entry is only available in German.
The forest administration has already built a barrier and an overrun to maintain the constant waterlevel.
This nice addition to the Urseetalfauna does not disturb the existing flora or fauna, does not keep the agronoms from their work and is so far from the civilization as is possible in the Urseetal.
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.
While putting all pictures from four years of observation into file, the next butterfly, the 47th in the Urseetal appeared: Argynnis niobe – Niobe Fritillary.
This butterfly lives in Baden-Württemberg (BW) almost exclusively in the Blackforest, preferably in the Hochschwarzwald and isolatedly on the Suebian AlB. Here it is suckling from red clover. Due the limited number of observation this species is not well researched, oviposition and the preferred larval plants are unknown.
This endangered butterfly is protected by federal law.
Today this beautiful beetle (Carabus auronitens) crossed my way. From the golden ground beetle (Carabus auratus) it differs by two main criteria: here only the first section of the antennae is read while C.auratus has four sections colored; the elytra (hardened forewings) have blackened longitudinal stripes. This beetle lives of snails, worms and other insects, up to 150 percent of its own body weight per day. C. auronitens is like all Carabus species protected by law.
Today, apart from Red Admiral (Vanessa atalanta), Peacock butterfly (Nymphalis io) and Small Tortoiseshell (Nymphalis urticae) I took pictures of the Purple Emperor (Apatura iris; 1st photo alive) in the Urseetal.
Red Admiral – Apatura iris
This butterfly usually lives at the top of trees and is thus rarely seen. This one loved dog-shit. Species specific is the lack of an eyespot on the anterior wing upperside and the red colorization on the posterior wing underside as well as the spike in the white band there. Specifically protected by federal law, in Baden-Würrtemberg under observation (Part of the Red List of endangered species)
On 12th and 16th of June, this butterfly could be observed.
The Lepiforum (Forum for butterflies and their friends) and Peter Simon from Titisee-Neustadt helped to identify the animal. Thanks a lot!
