Abstract: The loss of biodiversity, or species richness, is a growing global environmental concern. At the same time, biodiversity forms the foundation for critical ecosystem services and overall ecosystem health. A substantial body of evidence demonstrates the benefits of spending time in nature for human health; however, less is known about the role of biodiversity in human well-being. This study examines the influence of biodiversity on mental well-being, with a focus on mood and perceived restoration. Using a field experiment, we tested the effect of a biodiversity education sign on forest visitors’ mental well-being. We also measured mammal, bird, and vegetation species richness, along with visitors’ perceptions of biodiversity. Visitors reported significantly improved mood and perceived restoration following their experience in the forest. Model-averaged results indicated that perceived overall biodiversity, soundscape pleasantness, the sign intervention, and season (winter vs. summer) influenced mental well-being outcomes. In contrast, actual biodiversity and perceptions of specific taxa did not affect mental well-being outcomes. While these findings are specific to our study location, they contribute to growing evidence that time spent in nature enhances mood and promotes restoration, and they highlight the importance of perceived ecological quality and soundscape in shaping these experiences. Additionally, educational signage represents a simple, low-cost strategy for improving visitor experiences through biodiversity awareness. Overall, this study demonstrates the value of biodiversity and its role in supporting human well-being.
