EXPERTS at Stirling University have been chosen to lead a new £800,000 international study into forests and climate change that will involve studying 10,000 trees in 25 different countries.
The ForeSight study is designed to predict and monitor the response of European forests to drought and temperature change. The project will anticipate how forests will be adversely impacted as the climate warms and becomes more extreme, hampering tree growth, and causing dieback and mortality.
Stirling’s Professor Alistair Jump will lead the study, which is funded by the Natural Environment Research Council (NERC) and involves colleagues at Durham University, Forest Research, the Technische Universität Dresden and the Technical University of Munich.
Jump said: “More intense drought and increased temperatures reduce tree growth and drive tree dieback and mortality across the globe.
“While this problem has been recognised for some time, the processes and geographical extent of forest growth reduction and die-off are not well understood.
“Predicting the response of Europe’s forests to drought and temperature change is a key challenge because forests have enormous economic and ecological benefits that will be impacted as climate warms and becomes more extreme.
“This new funding will allow us to adopt an interdisciplinary approach to address these issues by predicting and monitoring drought-linked forest growth decline across the continent.”
Biological and Environmental Sciences at Stirling will receive £526,000 under the new project, which will focus on European beech – the most widespread broadleaf tree in Europe, covering more than 15 million hectares. Beech produces valuable wood and fibre, which is used diversely and is known to be at high risk from drought-linked dieback and mortality.
The research will link satellite observations and process-based models calibrated from a data network that provides a detailed picture of tree growth from about 10,000 trees across 25 countries.
The data will enable the team to model the processes and extent of tree growth suppression and to map and monitor drought-stress vulnerability across the entire range of beech. New tools developed in the project will support forward planning for UK forest management.
Jump added: “This work will contribute major new scientific insights into forest growth reduction and die-off in response to drought, with substantial benefits for improving our understanding of impacts on our ecosystems and atmosphere.”
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
