Microphones reveal when trees suffer from drought stress
Trees exposed to drought emit sounds – and with the help of microphones, researchers can now listen in as their water transport systems begin to fail. A new study from SLU shows that ultrasound from the forest can reveal whether trees are suffering from permanent drought damage.
The discovery could become a new tool for detecting climate stress in forests.
Forest damage and plant pests in focus as State Secretary Daniel Liljeberg participated in excursion
On International Plant Protection Day, 12 May, the Minister of State for Rural Affairs, Daniel Liljeberg, visited the forests of Öster Malma during an excursion led by the SLU Forest Damage Centre. The visit was his second to SLU
Long-term monitoring of spruce bark beetle shows a steady decline in numbers
The annual report from SLU's long-term monitoring of the spruce bark beetle has now been published and researchers are seeing a steady decline in the number of flying spruce bark beetles. SLU's long-term monitoring of spruce bark beetle has been measuring the number of flying bark beetles and the number of spruce trees killed since 1995. The aim of the monitoring is to create a data base for reliable analyses of what drives spruce bark beetle population size.
From Ancient Oaks to Forest Pathogens: Conference Excursion Highlights Biodiversity Challenges
Over 30 attendees of the 14th Conference of the European Foundation for Plant Pathology in Uppsala took part in an excursion to Morga hage nature reserve and a nearby pine forest, organized by the SLU Forest Damage Centre.
The group enjoyed scenic views of pastures and wooden meadows while also witnessing the strong impact of tree diseases such as ash dieback and Dutch elm disease.
Need for an integrated risk management strategy for forest fires in the EU
An integrated risk management strategy for Europe, adaptations to face more intense fires, longer fire seasons and increased risks in fire-prone areas were discussed among researchers, policy makers and practitioners in Brussels.
She maps the movement of moose in the managed forest landscape
How are moose movement patterns affected by our managed forests? This is what PhD student Desirée Guidobaldi Stenbacka is trying to find out and hopes that this understanding can support a more sustainable coexistence between moose and forestry.
The SLU Forest Damage Centre announces a call with focus on monitoring of forest damage. The call is for short-term monitoring projects that focus on method development and will be carried out in 2026 or until early 2027.
How does soil carbon storage look after fire and logging?
When forests burn or are felled, it is not just what we see above ground that is affected - the invisible carbon balance of the soil is also disturbed. In a new Fakta Skog publication, SLU researchers show how complex underground processes determine how quickly forest carbon stocks can recover after major disturbances.
If you report damage to trees and forests via Skogsskada during the period April to September, you can now take part in a prize draw for nice t-shirts and caps.
To be entered into the draw, report one or more detected damages to trees and forests in the web tool skogsskada. Go to skogsskada.slu.se and follow the instructions under ‘report damage’.
We will contact the winners by email when the competition is over.
Good luck to you!
