Research Summary This report presents the results of analyses of data from three sources: an online, UK-representative survey (n= 850), in-depth interviews (n = 34), and 808 photographs of nature taken by the interview participants. Four research questions were addressed through the analyses: 1. What terms did people use to describe trees and treed places? 2. Were tree-focused places perceived as more natural? And did respondents feel more connected to nature in tree-focused places? 3. How important were trees and different treed settings in participants’ nature engagement experiences? 4. Were trees and treed places associated with greater wellbeing? Key Findings 1. General terms for tree (e.g. “tree”) and treed environments (e.g. “woodland”) are in much wider use than more specific terms (e.g. “grove”, “orchard”, “oak”). 2. Tree-focused places (i.e. places where trees & woodland were mentioned) were perceived as more natural than places without a tree focus, with respondents perceiving more greenery, animals, birds and insects, natural sounds, and natural materials. Respondents also felt more connected to nature in tree-focused places. 3. Both the survey and photo analyses evidenced the key role of trees in participants’ nature engagement experiences, with trees regularly featuring in photographs, and participants engaging with trees in a range of settings (in woodland, outside of woodland, in urban and rural locations). 4. Trees & treed places contribute to perceived wellbeing in a range of ways. Key Recommendations 1. Researchers and practitioners need to take on board peoples’ language preferences and design future studies and interventions according to their level of understanding/usage of various terms for “tree”. 2. Researchers and practitioners could explore the potential value of 'the presence of trees' as a proxy for greater perceived diversity (of sounds, habitats, lifeforms) in an environment. 3. Research should examine the perceptions of trees in different settings (in/outside woodland, in urban/ rural locations), as well as capture a range of activities and motivations for engagement with trees. In particular, more research is needed on the perceptions and benefits of rural trees outside of woodland. 4. Researchers and practitioners should further explore, understand and promote the different wellbeing benefits of trees, as well as explore ways that promoting the public health benefits of trees could further support other areas of tree-related research, policy and practice, such as tree and land management.
