This chapter examines the potential presence and loss of expressions of intangible cultural heritage (ICH) concerning nature and the universe among displaced migrant communities in the United Kingdom, with a focus on policy gaps and safeguarding opportunities. This includes traditional ecological knowledge, seasonal rituals, spiritual worldviews, and land-based practices—knowledge systems recognised under the 2003 UNESCO Convention for the Safeguarding of Intangible Cultural Heritage and classified under the domain ‘knowledge and practices in relation to nature and the universe’. Although such forms of ICH may contribute meaningfully to sustainability and climate adaptation, they are especially vulnerable to disruption during displacement and resettlement. Based on desktop research, UK census data, and exploratory outreach in Exeter, UK, this chapter reflects on the challenges of identifying and supporting ICH among migrant populations, particularly when cultural expressions do not align with institutional definitions or inventory frameworks. It draws on global case studies and UK policy developments to argue for more inclusive, rights-based heritage approaches that centre migrants as knowledge holders. The UK’s 2024 ratification of the 2003 UNESCO Convention provides a timely opportunity to reframe how displaced heritage is understood and supported in policy and practice.
