I’m presenting FORESTS & CO’s results on primary forests, including challenges and trade-offs when it comes to carbon management at the UNFCCC-COP24 Climate conference in Katowice. I hope to see you there!

Forests host a huge range of animals and plants, and provide a wealth of services to us, including the provision of timber and other forest products (mushrooms!), protection from landslides and avalanches in mountain areas, clean water and clean air. In addition, forests capture and store large amounts of carbon, mostly in wood and soils, thus contributing to mitigating climate change. When managing forests, we should keep all these services in mind, and since not all of them can be maximised at the same time, make choices and set priorities. In our paper ‘Trade‐offs between carbon stocks and biodiversity in European temperate forests’, recently published in Global Change Biology, we focus on one of the possible trade-offs. Can we manage forests to both support biodiversity and maximize the amount of carbon they store? In short, can we fill two needs with one deed?
The European Union is about to release a revised version of the Directive on renewable energy. The directive aims at doubling the current production of renewable energy by 2030, i.e. the provision of solar, wind, hydroelectric and bioenergy energy. Renewable is ‘good’, so it seems we are undertaking a new step towards sustainability and a green future- All really noble, but are we sure we are doing the right thing?
Forests play a major role in the global carbon cycle, contain a substantial proportion of the world’s terrestrial biodiversity, and are valued for the services they provide to society1,2. Forest products alone are estimated at $120 billion annually3, although this estimation disregards the value of regulating, cultural and supporting services3. Importantly, forests are major carbon pools and play a critical role in mitigating climate change4, while harboring the majority of the world’s biodiversity2.
Unfortunately, the rate of biodiversity loss is still alarmingly high and accelerates5, which is worrisome considering emerging close links between biodiversity, ecosystem functioning, and human well-being.
A large body of evidence now suggests biodiversity loss affects the functioning of ecosystems. Likewise, high species diversity is often associated with high productivity and ecosystem service (ES) provisioning, including carbon storage and sequestration. Protecting forests and managing them sustainably is therefore important both to preserve biodiversity, and the services it underpins. However, our ability to understand the consequences of biodiversity loss on the supply of a portfolio of multiple ES is still incomplete.
