Abstract
•We explored householders’ nature connectedness and well-being during Covid-19.•Stronger nature connectedness was associated with more positive emotions.•Nature connectedness predicted indicators of private garden biodiversity.•Nature connectedness may provide both environmental and human health benefits.
Private gardens have an enormous impact on urban biodiversity, making individual householder behavior critical to the conservation and enhancement of biodiversity in urban areas. Nature connectedness is considered to be a prerequisite for proenvironmental behavior, but how it manifests in private gardens is largely unexplored. Nature connectedness has also been found to be associated with several well-being dimensions. The present study investigates the associations between nature connectedness, biodiversity of private gardens, and mental well-being during the Covid-19 lockdown, a stressful period in many people’s lives. Hierarchical regression analyses were used to analyze data from an online survey of private gardeners in two cities, one in Germany and one in New Zealand, in May 2020, approximately two months after the beginning of the first Covid-19 lockdown. Garden characteristics explained a significant amount of variance in depression symptoms during the Covid- 19 lockdown. In light of rising pressures on urban green spaces, the findings point to the importance of private garden qualities for mental health and well-being. Nature connectedness emerged as a significant predictor of feature richness, a measure of the heterogeneity of habitats that support wildlife, and plant growth form richness in people’s gardens in both city samples. Nature connectedness was also a significant predictor of the extent to which people experienced positive emotions during the Covid-19 lockdown but not negative emotions and depression symptoms. Our results suggest that nature connectedness can provide benefits for both the environment and people through its positive association with private garden biodiversity and positive emotions.
