USING NATURE-BASED CITIZEN SCIENCE INITIATIVES TO ENHANCE NATURE CONNECTION AND MENTAL HEALTH

This study investigates whether participating in nature-based citizen science initiatives serves as an effective health and wellbeing intervention. Researchers evaluated eight outcomes—including connection to nature, symptoms of depression, stress, anxiety, and emotional states—across five different initiatives in Australia and Germany. These initiatives varied significantly in their ecological focus (urban parks, forests, and streams) and the duration of participation, which ranged from 15 minutes to 48 hours. By using a before-and-after survey design with 253 participants, the authors assessed whether these initiatives could bridge the gap between biodiversity monitoring and public health.

Participants generally reported improvements across all measured mental health and nature connection outcomes. However, the magnitude of these improvements was not uniform. The most significant shifts were observed in immediate emotional states, such as a reduction in stress and anxiety and an increase in positive affect. Notably, only one initiative (Queensland Trust for Nature) showed statistically significant, robust enhancements in mental health and emotions after controlling for socio-economic factors. The authors attribute this to its longer duration and higher level of social interaction compared to the shorter, more individualized tasks found in the other projects.

This research highlights that while "micro-doses" of nature during citizen science can boost transient emotions and reduce acute stress, these activities may be insufficient to address deeper-rooted issues like chronic depression or to fundamentally alter an individual's long-term connection to nature. The study suggests that to maximize public health benefits, citizen science programs should be intentionally designed to incorporate extended engagement and social components, rather than viewing wellbeing benefits as merely a secondary byproduct of data collection. By aligning these initiatives with public health strategies, organizations can better leverage nature to support both scientific and societal health goals.
