Planting huge numbers of trees to mitigate climate change is “not always the best strategy” – with some experimental sites in Scotland failing to increase carbon stocks, a new study has found. Experts at the University of Stirling and the James Hutton Institute analysed four locations in Scotland where birch trees were planted onto heather moorland – and found that, over decades, there was no net increase in ecosystem carbon storage. The team … found that any increase to carbon storage in tree biomass was offset by a loss of carbon stored in the soil. Dr Friggens said: “Both national and international governments have committed to plant huge numbers of trees to mitigate climate change, based on the simple logic that trees – when they photosynthesise and grow – remove carbon from the atmosphere and lock it into their biomass. However, trees also interact with carbon in soil, where much more carbon is found than in plants.
