The Hazel Dormouse as Climate Ambassador

Is the Hazel dormouse the key to understanding the climate? The research project explores how the hazel dormouse can enhance public understanding of the impact of climate change on biodiversity and ecosystems, as well as engage citizens in conservation efforts.

The European Climate Law has set an ambitious goal of achieving climate neutrality in all EU countries by 2050. However, many people are still unaware of how our daily actions affect the climate and how climate change impacts biodiversity and the ecosystems around us. In an exciting collaboration between SDU and Naturama, this project aims to raise awareness about climate change and biodiversity using the hazel dormouse (Muscardinus avellanarius) as an ambassador species.

 

Why is the hazel dormouse important?

The hazel dormouse is the only dormouse species found in Denmark. This charming little creature faces significant challenges due to climate change and habitat loss caused by landscape fragmentation and intensive forestry, which has led to the species becoming endangered in Denmark. The hazel dormouse serves as an indicator species in Danish forests and woodland, meaning that its condition can provide us with valuable insights into the health of the ecosystem. It is therefore crucial to develop management and conservation strategies to secure the species' future. The project investigates how the hazel dormouse and the research into its vulnerable status in Denmark can enhance public understanding of the current climate change-driven effects on biodiversity and ecosystem functionality.

 

New knowledge about the hazel dormouse

Researchers have collected data on hazel dormouse populations in Denmark over several years, but many questions still remains unanswered. This project continues these important efforts, using the data to examine how climate change is affecting Danish hazel dormouse populations. Additionally, the project will study the genetic diversity among the Danish subpopulations to understand how different groups might be impacted by environmental changes. 

 

The hazel dormouse in school

Studies have shown that children's interest in science subjects often declines when they reach middle school. It is therefore crucial to create a positive and engaging connection to nature science during this period. This project explores how the hazel dormouse can be used as a model species in education to increase students' interest and motivation to learn about climate change, biodiversity, and ecosystems. A new interdisciplinary teaching program, developed in collaboration with dedicated teachers from local schools and experienced educators, includes active learning in informal learning environments to engage students both inside and outside the classroom.

 

Help us find the hazel dormouse

An important part of the research is to map where the hazel dormouse lives in Denmark – and this is where you can make a real difference. The hazel dormouse is both shy and nocturnal, making it difficult to spot. However, it leaves behind signs that can reveal its presence if you know what to look for. We therefore invite anyone interested in nature to become hazel dormouse ambassadors and contribute to the research. Read more about how you can take part below.

By participating, you are not only helping to collect valuable knowledge, but also contributing to raising awareness about biodiversity and nature conservation in Denmark. Together, we can gain a better understanding of the hazel dormouse and strengthen efforts to protect it.
