Hirschkaefer-Suche is a Citizen Science project for the protection of the stag beetle (Lucanus cervus). The project is supported by the association Hirschkäferfreunde-Nature two e. V. It researches the habitats, distribution and biology of the stag beetle and works in many ways to protect the largest native species of beetle. It maps, examines tree stumps, relocates stag beetle habitats and builds artificial nests. 

For their development, stag beetles need old, rotting tree stumps that stand as sunny as possible. Their development takes 2-7 years. Most of their life they spend as larvae in the white-rotten wood of the tree stumps. The beetles find suitable habitats not only in forests but also in gardens and parks. Here they live particularly dangerously, because the habitats are usually not visible from the outside. With the removal of an old tree root, the habitat of an entire stag beetle family is frequently destroyed. In order to prevent this, the association has trained a dog to reliably track down the habitats.

The aim of the project is to identify stag beetle occurrences as comprehensively as possible in order to better protect them. On the website "hirschkaefer-suche.de", private individuals can therefore also report their own observations and finds. With the information gained in this way, "residence maps" of the stag beetle are created and they serve scientific work. The portal registers about 1,500 reports annually. Through environmental education measures such as the stag beetle diploma for children, the association sensitizes the population to the stag beetle. The project has developed into a competent advisor for questions about the stag beetle and other large beetle species.
