Surface water and groundwater benefit from the preservation of old-growth forest

  • Nutrients and heavy metals remain in the soil rather than being released into rivers, lakes and seas. Vehicle damage on the forest area increases leakage of mercury into rivers and lakes twofold, contributing to unsuitably high levels in fresh-water fish, and fish along the coast of the Baltic, especially predatory fish like pike. This in turn increases the levels of heavy metals and toxins further up the food-chain among for instance birds of prey, seals, and humans.
  • Old-growth forest contains twenty times more rotting wood than industrial forest. Rotting wood from undisturbed old-growth forests contributes to a thriving ecosystem when it enters rivers and streams, creating a better environment for the reproduction of for instance wild salmon.
