A multi-study research program has concluded that the presence of trees—particularly mature canopy trees—affects how people shop and spend. While much research has been done on how interior environments such as lighting and music affect consumer preferences, very little hard research has been done on how exterior environments affect people’s behavior.
Study participants reported they would be more likely to shop, pay for parking, and spend more in environments with large canopy trees. Merchants often prefer smaller ornamental trees because they fear large canopies will block store signage. The study emphasized how the co-design of signage and vegetation can resolve these issues.
