The semi-natural hay meadows have been of great importance for Norwegian agriculture for thousands of years (Bele et at. 2024). With the modernisation of farming practices and the abandonment of traditional knowledge, these landscapes have become fragmented (Bele et al. 2024) and are now red-listed habitats in Norway (NEA 2024). However, the inclusion of intangible cultural heritage and traditional ecological knowledge (TEK) could play an important role in nature management, where traditional farming can promote maintenance of semi-natural hay meadows. I have based my thesis on former experience, participant observation, and semi-structured interviews to discuss the dynamics between TEK and landscape management strategies. My first research question concerns (1) the role of Traditional Ecological Knowledge (TEK) at Havrå, a farm cluster located on the island of Osterøy (Vestland). The farm is a living memory of traditional western Norwegian farming. Today, some of the farms are managed by Museumssenteret i Hordaland (MUHO), and in their daily work, traditional techniques are still practiced. Secondly, I have studied how (2) TEK at Havrå can contribute to sustain hay meadows as a landscape type. The “ineffective” farming methods help maintaining the natural diversity of animals, plants, lichens and fungi, but have also created a unique landscape that is open and accessible for human activity. Finally, I discuss (3) how subsidising TEK as a management strategy at Havrå can promote (or constrain) sustainable actions. Havrå is a place where subsidies are utilised to ensure the continued practice of old traditions. While some suggest that subsidies can promote sustainable management, other scholars are more hesitant to utilise countryside schemes as tools for agricultural sustainability transformation (Burton & Paragahawewa 2011).
