The price tag for the project, which is set to last until 2030, amounts to 86 million kronor, reports SVT Nyheter Helsingborg.
In total, there are 5,300 trees in deciduous forests in Skåne, on Hallandsåsen, Blekinge and Kronoberg, as well as four areas in Belgium.
A tree can live up to 400 years, but once they are around 200 years old they start to become especially important for biodiversity. They have cracks and cavities that benefit mosses, fungi, but also insects, birds and bats, says project manager Tove Hultberg to SVT.
Veteranization is a relatively new method, and the trees are carefully selected. Scientists then monitor how the flora and fauna are affected.
