Sweden Nature Conservation Agreements — Naturvårdsavtal

Sweden's Nature Conservation Agreements (Naturvårdsavtal, NCA) are voluntary 50-year contracts between the Swedish Forest Agency and private forest owners, running since 1998. Landowners agree to refrain from commercial felling and to manage their forest for biodiversity — retaining dead wood, old trees and structural complexity — in exchange for compensation payments equal to the estimated timber value foregone.

Protect old-growth and biodiversity-rich forest on private land without compulsory purchase, complementing formal nature reserves with a voluntary, negotiated instrument.

The Swedish Forest Agency negotiates and administers individual 50-year NCA contracts with private landowners, compensating them for foregone timber value. A companion instrument, Biotope Protection Areas (BPA), covers additional forest under a related mechanism. Annual statistics on area, compensation and enrolment are published transparently by the agency.

By end 2025, more than 35,500 hectares of productive forest were under NCA agreements, with the companion Biotope Protection Area (BPA) instrument covering a further 34,600 hectares — a combined NCA+BPA network of 76,600 hectares. Average NCA compensation in 2025 stood at approximately SEK 23,000 per hectare, and cumulative NCA compensation expenditure since inception has exceeded SEK 600 million. Peer-reviewed research (Svensson et al., Restoration Ecology 2025) confirms that NCA and BPA patches, while individually small (average 7.2 ha per patch), collectively make significant contributions to landscape-level biodiversity conservation, particularly for old-growth-dependent species such as saproxylic beetles and lichens.

The NCA model is a cost-efficient approach to private-land conservation that has been cited in international literature as replicable and has inspired similar schemes elsewhere in the Nordic and Central European region. Its growth is nonetheless constrained: new annual enrolments have fallen to a historic low (995 ha added in 2025) because the same budget is increasingly diverted to compensating landowners for denied logging permits in montane forests, a governance tension that limits further programme expansion.
