The more (carbon in forest), the better (for biodiversity)?

 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?

Are we asking too much of species data?

To conserve biodiversity, we need a clear picture of how it is distributed. Easier said than done! Biodiversity is a short word for a wide concept. Even just counting the number of species in a forest can be an overwhelming task if one considers all insects, spiders, birds, mites, (ticks!), lichens, fungi, isopoda and so on. Not only, some of these groups are very difficult to identify, so sampling them all would require hundreds of hours to a team of well-trained field biologists.

Can we rely on one or few groups of species to make inferences on all the other, then? Although the use of indicators is a well-established routing, how well these indicators work in Southern European beech forest is not clearly understood. One of the open questions is: How well do indicators work at different scales? In our new article Congruence across taxa and spatial scales: Are we asking too much of species data?”, just published in Global Ecology and Biogeography, we tried to find an answer.
