On this page we keep you up to date about everything concerning the BioDiversum. How is the progess on the construction work? What animals and plants are there to see? What else is going on? Find out here!

The common twayblade - a rather inconspicuous native  orchid species - blossoms.

Everything is green!

With the sunny spells and scattered showers during the last weeks, the vegetation in our biotope has now blossomed and turned green. Some of our nesting boxes are now actually difficult to find behind all the leaves. The flowering meadows, which we planted last year with regional seeds, change their colors almost weekly. In addition, they now provide food and habitat for all kinds of insects.

Our pond works are progressing at a fast pace!

A layer of foil and fleece now covers the ponds’ bottom to make it leak-proof. Next comes a layer of mortar before it can be filled with the actual soil. Hopefully, by the end of the month, we can say "Let the water flow!".

Finally, the first five swift boxes are hanging (two are visible on the picture in the upper left of the building), yet whether they will be occupied this year is uncertain. Swifts remain quite loyal their breeding locations and do not easily settle in new areas. However, we are optimistic that they will discover our nesting boxes sooner or later. 

It is becoming increasingly difficult for swifts to find suitable nesting sites. On the one hand, they are synanthropic, meaning they nest in human settlements, which are taking up more and more space. On the other hand, by demolishing or old buildings and sealing roofs we are making it increasingly difficult for them to breed. The more important it is today that we offer these extraordinary birds alternative nesting opportunities.

Our pond is now completely excavated and the walls are finished. The stepped structure can be seen very clearly. In the deepest area it will be three meters deep. There is also a zone of medium depth and a shallow shore area. Once there is water in the pond, these three zones will result in three different habitats with different conditions from water temperature to the incidence of light and oxygen concentration.

Some have merely been hanging for two weeks, yet, a few of our nest boxes were immediately occupied! Here, a pair of great tits is already busy flying back and forth to their nest. From other boxes, we unmistakably perceive the chirping of fledglings.

In the meantime, the earthworks for our pond have made considerable progress. Its future shape is already recognizable.

There is also a lot going on at the area in front of tower 1 of our institute. The course of the new footpath is now clearly visible. Soon we will plant flowering shrubs and other woody plants. We are also setting up two charging stations for e-cars in the adjacent parking areas.

During the last weeks, more than 80 nesting boxes have found their places on our grounds, especially along the edge of the forest. We try to offer nice homes for as many different bird species as possible: We have nest boxes with large, small, or oval entrance holes, half-caves, boxes for starlings... We are looking forward to see how they will be accepted!

By the way, there are five nesting boxes hidden in the photo – who can spot them all?

Since the end of March, a kestrel box made by our carpentry has been hanging high up on tower 6 of our institute. And lo and behold: It is already occupied! The pair of kestrels is constantly flying in and out and is obviously busy preparing their nest for breeding.

The excavator has finally arrived – today the earthworks for the pond started! Earthworks were actually supposed to start on March 8, but it was delayed due to the bad weather. If everything goes according to plan, the wetland biotope and thus the central element of the BioDiversum will be ready by the end of spring.

January 14, 2021

Our year-round bird feeding station is ready! With this measure we want to increase the density and biodiversity of breeding birds. The bird feeder was built by our team in our carpenter’s workshop.

To not disturb the animals, shrubs will be planted around the feeding station. To make sure that the birds can still be observed at a sufficient distance, we plan to cut viewing slits in the bushes.

For the time being, the Corona pandemic threw a wrench in the works of our plans. The construction of the pond has to wait. But the first flowering meadow can grow! We want to transform our extensive species-poor, regularly mowed green areas into biodiverse meadows. To do so, we first carefully cut through the turf and allowed it to dry. Afterwards, the soil was largely devoid of vegetation and we sowed a meadow mixture with a high proportion of wild shrubs and herbs.

In the flowering meadows, bees, butterflies, bumblebees and other insects shall find nectar and breeding refuges. Not only the creepy-crawlies benefit from this, but also birds, amphibians, small mammals, reptiles and many more.

Summer/Autumn 2019

Ornithologist Michael Corsmann

Over the summer, experts determined the diversity of the current flora and fauna on our institute grounds. Many thanks to Gerd Brunken, Michael Corsmann, Thomas Fechtler, Jürgen Rommelmann, Mareike Schneider and the office Wette+Küneke for their expert services! We intend to repeat this inventory at regular intervals in the coming years. This allows us to assess the effects of our emerging BioDiversum on the flora and fauna.

More information about the inventory can be found here.

Spring 2019

Green light for the biotope!

The concept for our biotope is ready, the building application has been approved. Now it's time for implementation. An overview of all measures can be found here.

March 2019

On-site inspection of the institute premises with Peter Berthold (middle) in March 2019.

Ornithologist Peter Berthold comes to visit our guest. He has a wealth of experience in creating biotopes and propagates a network of renaturalized areas throughout Germany under the motto A biotope for every community.

 Together we want to develop ideas for the design of our BioDiversum. Initially, the focus for the biotope is on the approximately two hectares of waste ground at the northeastern end of our institute`s premises. Peter Berthold proposes a large pond, a meadow orchard as well as compost heaps and a bird feeding station. He also sees great potential for ecological enhancement of other undeveloped areas of the institute. And with each new idea Berthold comes up with, it becomes more and more obvious that the biotope project cannot just be limited to the waste ground, but must extend across the entire premise all the way to the entrance area. Based on this conviction, our Biotop team will develop the concept for the BioDiversum in the coming months.
