The aim of this research is to acquire an in-depth understanding of how organized nature-based integration activities can impact recently arrived immigrants’ place attachment. This qualitative study is based on participant-observation of organized nature-based integration activities in Helsinki, Finland, and semi-structured interviews with five of the participants. The research combines social integration theory used in previous studies of nature-based integration with Scannell and Gifford’s (2010) model of place-attachment. The results of the research show how nature-based integration activities had a positive impact on recently arrived immigrants’ place-attachment, as they 1.) promoted health and wellbeing, 2.) increased social interactions, 3.) transferred culture-specific knowledge and 4.) increased independence and confidence in a new environment.
