What the study found
The study found that perceived environmental quality was related to restoration outcome in urban greenspaces. Perceived beauty and perceived diversity were especially important, and greenspace size showed a partial mediation through these perceptions.
Why the authors say this matters
The authors conclude that perceived environmental quality is important for restoration outcome. They also frame human-nature interactions as potentially relevant for the prevention and salutogenesis of adverse mental health conditions related to urban stressors; salutogenesis means the factors that support health.
What the researchers tested
The researchers analyzed greenspace and survey data from 728 observations in 48 plots within 31 greenspaces in inner-city Munich, Germany. They tested mediation models with objectively measured greenspace characteristics as predictors, perceived beauty, diversity, and naturalness as mediators, and restoration outcome as the outcome.
What worked and what didn't
There was a partial mediation between restoration outcome and greenspace size through perceived beauty and perceived diversity. Vegetation density of the subcanopy was positively associated with restoration outcome, but no mediation was found for that relationship. Perceived beauty, diversity, naturalness, time spent in the greenspace, and nature connectedness were all positively related to restoration outcome.
What to keep in mind
The abstract does not describe experimental intervention or causal testing, so the results are based on observed associations and mediation models. The summary is limited to greenspaces in inner-city Munich, Germany, and no other limitations are stated in the available text.
