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 Urseetal we 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.
Manfred G. Haderer has published an article on the Urseetal in the Badische Zeitung, the local Newspaper, which refers to mainly three points: latest development in the Urseetal, species diversity and richness of butterflies, and management and care for appropriate butterfly environment.
We welcome all readers who have found this page via that article.
On Saturday, 30th of July, some 14 people met for a field trip into the moor of Hinterzarten. Siegried Kognitzki (SK) was the tour leader.
After introducing development and requirement for forming a moor, SK demonstrated the different zones of a moor and its surroundings. Moor specific plants and animals living in the moor and around were presented. Due to cold weather the insects were almost missing: a single dragonfly was observed. Grass frog larvae are not really moor specific. Along the walk, plants specific for the moor were seen: Vaccinium uliosum (compared to Vaccinium myrtillus), Potentilla palustris, Menyanthes trifoliata, as well as Andromed polifolia. Pinus mugo spp. uncinata/rotundata was compared to Pinus sylvestris, Moor birches compared to usual birches. Typical moor forming plants are and several of them were presented.
Walking around the moor, several grasshopper were found and identified. Finally a single Melitaea athalia (heath fritillary) could be seen.
The afternoon was favoured by dryness, but it was much to cold for end of july. After three and half hours the participants a mixed group of tourist and locals were back at the train station. They thanked SK for this informative afternoon.
In the springtime, spruces had already been removed around the moor. Now, much earlier than expected, spruces are cut in the floodplain futher down the valley. Around the former dumpsite all spruces have been removed, the valley becomes thus open to look at from the street to Raitenbuch. As of now, friday afternoon, almost all the spruces have been cut, it remains to clean the ground.
Since the ground is part of the moor, heavy full harvesters or log transporters can only work from the rim where the ground is firm. Therefore alle trees are cut down hand-operated, drawn to the rim where they are processed further.
No recultivation is planned by the different offices, the place will be left to itself, regular spruce removal may take place.
This project finished, a further point which the team Ursee within the Kulturlandschaftsprojekt had raised got performed.
On wednesday this week, Manfred G. Haderer published a report in the Badischen Zeitung.
