@PIK_climate The bark beetle is not the cause of forest dieback. It is the mortician of a dying forest. Please do not plant root-pruned trees from the tree nursery. At best, plant seedlings of old native species and let the forest do the work itself. Freely and hopefully correctly according to Peter Wohlleben.
I don’t know about Wohlleben, but it is certainly true that a forest health is intimately related to the biome under the soil that it lives in symbiosis with.
You’re going to see 2/3 of all the carbon and water in the soil itself in the living biomass.
Of the kinds of reforestation that seem to work the best it’s leaving tiny patches of old growth and let nature do its thing. Otherwise, Miyawaki.
