In Blauen BL, artificial ponds offer a safe home to the endangered “Glögglifrog.” An ideal family outing with a slightly creepy touch.
The colourful nature meadow is teeming with life. Grasshoppers are jumping briskly from one blade of grass to another, while beetles and ants make their way through the jungle of flowers and herbs. Wasps are buzzing around. Moles are making their way through the dry earth, as if turning it into Emmental cheese.
Moles, birds, dragonflies and all kinds of beetles live around the densely overgrown pond in the middle of the scenery.
Amazing biodiversity
We are on a meadow outside the village of Blauen BL with its 700 inhabitants. You can reach Blauen by train and bus from Basel in 45 minutes, or in even less by car. An ideal outing for families in Basel. After all, the pond is teeming with biodiversity: Blackberry, hawthorn and blackthorn bushes are competing for a place in the sun. Pink autumn crocuses bloom as a splash of colour around the pond, and a few metres up the slope stands a mighty walnut tree. But in particular, a spooky, fascinating toad with a strange name lives here – the midwife toad.
By the way: Primeo Energie not only promotes sustainable projects, but also offers exciting and educational afternoons for children. In the workshop “Electricity from the Sun”, for example, children can make their own solar vehicles – perfect for a birthday party.
But where does the name midwife toad come from? The toad’s behaviour is quite special. When it mates, it looks as if the male is sucking on the eggs to extract them from the female. The eggs therefore leave the female in a row like a string of pearls. The male then wraps this cord around his hind legs and looks after them until hatching time.
The male midwife toad carries the fertilised eggs on his hind legs until they hatch.
The “Glögglifrog,” as the midwife toad is also known locally, lives in the ponds near Blauen that are lined up like a string of pearls and provide the endangered animal with a safe habitat. Despite its nickname, the “Glögglifrog” is a toad. It takes its name from its unusual mating call, which consists of short, high-pitched beeps reminiscent of a bell.
The “Glögglifrog”
Biological name: Alytes obstetricans
Size: 3.5 to 5 centimetres
Look: Vertical slit pupils, grey-brown back with warts
Mating time: The end of March to August. The mating calls can be heard during this time.
Behaviour: Likes sunny spots, which is why the ponds are also located on the south-facing slope.
The ponds provide a habitat for water lilies and pointed mud snails.
Exploring nature in spring
Although the midwife toad is threatened with extinction, there are some relatively large populations in Basel-Landschaft. To connect the regional “Glögglifrog” populations, four new ponds have been created in the area around Blauen. Together with the existing ponds, these are intended to help save the “Glögglifrog”.
Bulrushes also grow on the ponds.
If you want to study the “Glögglifrog,” it’s best to do so from March to August, when it starts its mating calls in the evening. If several males court females at the same time, it almost sounds like wind chimes. Courageous parents may consider handing their smartphone to their child so that the child can take pictures of the animal on their own. You can record the mating calls using the recording function. See, hear, smell – and capture digitally for all eternity. And don’t forget to check for ticks after your trip. We hope you will enjoy yourselves!

The eco-fund
Primeo Energie has been offering electricity with the “naturemade star” certification since 2010. Customers can purchase this electricity from 100% renewable energy sources for a small surcharge. One source of this electricity is from two small hydropower plants in Laufen and Dornach, which are operated by the aventron company. For every kilowatt hour sold, one centime goes into the eco-fund, raising around CHF 75,000 each year. Primeo Energie is using this fund to finance ecological projects in the surrounding area, such as the ponds in Blauen, a pond restoration in Laufen and the renaturation of the Birs river. The eco-fund contributed CHF 45,000 to the above-mentioned project and thus financed half of it. aventron operates hydropower, wind and solar power plants in Switzerland, Germany, France, Italy, Spain and Norway.
