As the temperatures rise, a remarkable natural event unfolds—thousands of amphibians begin their annual migration toward breeding ponds. In Flanders, this seasonal journey often leads them across busy roads, where many face a deadly challenge. Fortunately, dedicated volunteers from Natuurpunt are stepping in to assist these creatures, ensuring as many as possible reach their destination safely.
A Race Against Traffic
Every year, passionate nature lovers take to the streets—not to protest, but to protect. At various hotspots across Flanders, volunteers carefully collect and carry migrating amphibians across roads, away from the dangers of passing cars. Thanks to their efforts, countless Common Toads (Bufo bufo), frogs, and newts make it to their breeding grounds unharmed. However, despite these heroic interventions, many still fall victim to traffic.
Learning from the Lost
While the loss of these toads is unfortunate, it also provides an unexpected opportunity for scientific research. As part of the Toad Project, researchers visit migration sites to collect deceased Common Toads. These specimens hold valuable data that help us understand amphibian health, ecology, and conservation needs. By studying the casualties, scientists can determine:
Toad Ages – Analyzing bone structures to understand population demographics.
Toxin Exposure – Detecting pollutants in their bodies to assess environmental health.
Genetic Diversity – Understanding population structures and potential vulnerabilities.
Herpes Prevalence – Investigating disease spread among toad populations.
Bufotoxin Levels – Measuring the natural toxins produced by toads and their variations.
Diet Analysis – Examining stomach contents to learn about their feeding habits.
Conservation in Action
This research not only deepens our knowledge of toad populations but also informs conservation strategies. By identifying threats and stressors, we can advocate for better protection measures, such as wildlife corridors, migration tunnels, and awareness campaigns to reduce road mortality. The migration season is a crucial time for amphibians, and every effort counts. Whether by volunteering, driving cautiously in migration zones, or supporting conservation research, we can all play a role in ensuring these incredible creatures continue their journey for generations to come.
