Across borders – the status and future opportunities for long-term conservation of Nordic animal genetic resources

Main Article Content
Abstract
The genetic diversity of multiple animal species is now declining rapidly, highlighting the need for action to protect and preserve animal genetic resources for the long term. The Nordic countries house a broad range of farm and companion animal breeds and subspecies that play a critical role in environmental sustainability, food safety and security, and human activities. Unfortunately, close to 80% of these breeds and subspecies are either endangered or critically endangered, with population sizes too small to ensure their long-term survival. In addition, almost half of them have either a declining or unknown demographic trend, and many of them suffer from high inbreeding. Emerging pressures such as climate change, infectious diseases and public unrest further threaten the status of the populations, and urgent action is necessary to ensure their future survival. Consequently, efforts for safeguarding the genetic diversity of animal genetic resources (AnGR) with additional in vitro or cryoconservation efforts need further consideration. The Nordic conservation strategies for AnGR have traditionally been based on in vivo or live conservation. Although cryoconservation efforts are in place for some species, the number of donors and doses varies considerably between breeds and species. Due to the increasing demand for additional measures for safeguarding AnGR, this document discusses the status of active AnGR conservation measures in the Nordic countries and emphasize the central role of regional cooperation in ensuring AnGR sustainability and long-term viability. Further, the contributions of cryoconservation in mitigating genetic losses are discussed.
