Bird protection at Riemer See: fence decided for breeding times!
The Trudering-Riem district committee is calling for seasonal fencing at Lake Riem to protect breeding birds and minimize annoying disturbances.
Bird protection at Riemer See: fence decided for breeding times!
Important changes are planned at Riemer See in Munich to offer the local birds a safe home during the breeding season. The Trudering-Riem district committee unanimously voted in favor of seasonal fencing of the wetland biotope on the northwestern bank. This fence will be erected from the beginning of May to mid-August and will create refuge for various bird species. The proposal submitted by the Greens is a step in the right direction to combat the dwindling bird population. tz.de reports that an inspection in April 2025 found that previously breeding species such as the moorhen and the coot have hardly been able to raise offspring in recent years.
The main cause of this decline in the breeding population is the disturbance caused by walkers and bathing dogs. Constant intruders make it difficult for the birds to find a suitable breeding place. The district committee hopes that the planned measures will not only lead to a recovery of the species, but also greater acceptance among dog owners. For this purpose, information boards should point out the area's need for protection and the existing dog bollards should also be made available for inspection.
Breeding season and species diversity
The demand for seasonal fencing affects a large number of bird species that have settled on Lake Riem over the last 25 years. These include moorhens, coots, little grebes, reed warblers, reed warblers and reed buntings. However, breeding success has declined sharply in recent years. This shows how important it is to take appropriate protective measures during the critical breeding phase. The Greens emphasize Trudering-Riem that targeted fencing ensures the safety of the birds during this time and at the same time preserves the animals' natural habitat.
Another aspect that affects bird life is the availability of natural food. A study by the Leibniz Institute for Zoo and Wildlife Research has shown that the abundance of vertebrates, particularly insects and spiders, directly influences bird diversity in urban areas. The more prey there are, the more diverse the bird community becomes. As research shows, this is particularly relevant in urban areas, where urbanization is altering the natural habitats of many wildlife species.
In order to boost bird diversity in Munich, it is crucial to develop further protection strategies and promote urban nature. The planned measures at Riemer See could be a good start and help to sustainably improve bird breeding. The support from the State Association for Bird Protection (LBV) and the BUND Nature Conservation will help to design the measures in a meaningful and effective manner.
