In Northern Finland, including sparsely populated Finnish Lapland and the small city of Rovaniemi, the widespread clearing of old trees has degraded the boreal environment. Disrupting the diverse relationships between people and trees, climate change will continue to alter the country’s northernmost forests, as is widely known. In this urgent context, we propose that the collaborative project Gifts from the Sentient Forest (GSF) has developed new modes of interacting with Northern Finland’s trees and appreciating their biocultural legacies. At the project’s core is arboreal sentience, a concept illuminating the capacities of trees to sense, communicate, behave, learn and remember. In the project, other-than-human sentience provides a basis for cultivating tree-human communication while expanding Lapland residents’ awareness of sylvan communities through painting, photography, film, music, poetry and performance. In this article, we present an account of three methods leveraged in the GSF programme to facilitate experiences of tree sentience in Northern Finland: sensing, interviewing (speaking) and remembering.
