That is the conclusion of a new study from the Swedish University of Agricultural Sciences (SLU). https://www.slu.se/en/news/2026/03/stor-felmarginal-i-globala-skogsanalyser/ https://www.slu.se/en/news/2026/03/stor-felmarginal-i-globala-skogsanalyser/ Thu, 19 Mar 2026 14:02:31 +0200 For several years, researchers at the Swedish University of Agricultural Sciences (SLU) have been collecting data on moose movements in the Junsele area. The aim has been to understand how moose and their migration are affected by changes in the forest landscape. The project is now coming to an end. https://www.slu.se/en/news/2026/03/migrating-junsele-moose-tracked-with-gps--research-project-now-reaching-its-end/ https://www.slu.se/en/news/2026/03/migrating-junsele-moose-tracked-with-gps--research-project-now-reaching-its-end/ Mon, 16 Mar 2026 08:02:00 +0200 At Fiskbarometern, SLU presents the status and trends of fish and shellfish stocks in Swedish marine and freshwater environments. The assessments for 2025 are now complete. The situation is most concerning in the Baltic Proper, while perch in Lake Vänern are on the rise. https://www.slu.se/en/news/2026/03/fiskbarometern-sa-mar-sveriges-fisk--och-skaldjursbestand/ https://www.slu.se/en/news/2026/03/fiskbarometern-sa-mar-sveriges-fisk--och-skaldjursbestand/ Thu, 12 Mar 2026 08:00:20 +0200 Climate change is expected to lead to increased nitrogen leaching in the Nordic countries. In his thesis, David Nimblad Svensson shows that growing cover crops is an important measure, that will become even more important in a future climate to reduce nitrogen leaching and preserve soil fertility. https://www.slu.se/en/news/2026/02/cover-crops-reduce-nitrogen-leaching-in-a-warmer-climate/ https://www.slu.se/en/news/2026/02/cover-crops-reduce-nitrogen-leaching-in-a-warmer-climate/ Fri, 27 Feb 2026 10:01:20 +0200 Despite decades of industrial deposition, nitrogen availability in the boreal forest is steadily declining. In a new study published in Nature, researchers from the Swedish University of Agricultural Sciences have found that atmospheric CO₂ is the main driver - using decades of unique, stored data. https://www.slu.se/en/news/2026/02/archived-tree-cores-reveal-why-boreal-forest-are-getting-starved-for-nitrogen/ https://www.slu.se/en/news/2026/02/archived-tree-cores-reveal-why-boreal-forest-are-getting-starved-for-nitrogen/ Thu, 19 Feb 2026 07:23:23 +0200 Sweden faces a unique opportunity to environmentally adapt hydropower and restore important environments in our aquatic ecosystems. However, success will require a holistic approach and systematic monitoring, according to two new studies from the Swedish University of Agricultural Sciences (SLU). https://www.slu.se/en/news/2026/02/miljoanpassningen-av-vattenkraften-kraver-helhetstank-och-systematisk-uppfoljning/ https://www.slu.se/en/news/2026/02/miljoanpassningen-av-vattenkraften-kraver-helhetstank-och-systematisk-uppfoljning/ Wed, 18 Feb 2026 08:00:10 +0200 How can SLU’s goldmine of forest data be put to the best possible use?

In a comprehensive study, researchers from 13 European countries show that eDNA can improve monitoring, but that the choice of method is crucial for how reliable the results are. https://www.slu.se/en/news/2026/01/ny-europeisk-studie-visar-vagen-mot-sakrare-overvakning-av-kraftor-och-kraftpest-med-edna/ https://www.slu.se/en/news/2026/01/ny-europeisk-studie-visar-vagen-mot-sakrare-overvakning-av-kraftor-och-kraftpest-med-edna/ Tue, 20 Jan 2026 15:24:33 +0200 Bats are fascinating animals – and key players in natural ecosystems. Researchers are now developing a new tool for species identification that will support research, conservation and even bat watching. https://www.slu.se/en/news/2026/01/researchers-sharpen-bat-monitoring-with-an-open-access-tool/ https://www.slu.se/en/news/2026/01/researchers-sharpen-bat-monitoring-with-an-open-access-tool/ Fri, 16 Jan 2026 08:10:43 +0200 Using recreational fishing and mark–recapture methods, researchers estimated how many pike live in a Baltic archipelago bay—2,449 individuals. When grey seals appeared, catches fell sharply, not because pike disappeared, but because their catchability declined. https://www.slu.se/en/news/2026/01/the-presence-of-grey-seals-affects-the-chance-of-catching-pike/ https://www.slu.se/en/news/2026/01/the-presence-of-grey-seals-affects-the-chance-of-catching-pike/ Wed, 14 Jan 2026 12:11:24 +0200 An ambitious and constructive implementation of the EU Nature Restoration Regulation provides opportunities for adapting forestry to the future, researchers at SLU say. A restrictive implementation risks continued unclarities, heated debates and conflicts on forests and forestry, they argue. https://www.slu.se/en/news/2026/01/researchers-on-the-eu-nature-restoration-law-opportunities-for-sustainable-forestry--and-less-conflicts/ https://www.slu.se/en/news/2026/01/researchers-on-the-eu-nature-restoration-law-opportunities-for-sustainable-forestry--and-less-conflicts/ Wed, 07 Jan 2026 08:12:21 +0200 Most of the antibiotics and antiviral drugs we use have changed when they leave the body. Many of these breakdown products can remain in aquatic environments for a long time with preserved biological activity and risk spreading antibiotic resistance, according to a new dissertation from SLU. https://www.slu.se/en/news/2025/12/antibiotics-in-surface-waters-breakdown-products-can-also-be-problematic/ https://www.slu.se/en/news/2025/12/antibiotics-in-surface-waters-breakdown-products-can-also-be-problematic/ Thu, 11 Dec 2025 10:44:31 +0200 A new study shows that the level currently used as a benchmark for maximum sustainable yield carries a higher risk of stock collapse than previously assumed. Almost the same long-term catches can be achieved with slightly lower fishing pressure, but with a significantly lower risk to the stocks. https://www.slu.se/en/news/2025/11/current-target-for-sustainable-fishing-involves.unnecessary-risks https://www.slu.se/en/news/2025/11/current-target-for-sustainable-fishing-involves.unnecessary-risks Thu, 27 Nov 2025 07:37:58 +0200 Are Swedish forest soils depleted in nutrients by forestry and increased tree growth? No, a new study reports that levels of important mineral nutrients have increased in the organic layer over the past 40 years. Reduced acid rain and uplift of nutrients from the mineral soil are suggested reasons. https://www.slu.se/en/news/2025/11/increased-amounts-of-mineral-nutrients-in-swedish-forest-soils-despite-intensive-forestry/ https://www.slu.se/en/news/2025/11/increased-amounts-of-mineral-nutrients-in-swedish-forest-soils-despite-intensive-forestry/ Tue, 25 Nov 2025 13:52:53 +0200 After more than 100 years of operation, Sweden’s first facility for compensatory fish farming of salmon and trout has now permanently closed its doors. https://www.slu.se/en/news/2025/11/slus-fiskeriforsoksstation-i-alvkarleby-har-nu-stangt-for-gott/ https://www.slu.se/en/news/2025/11/slus-fiskeriforsoksstation-i-alvkarleby-har-nu-stangt-for-gott/ Wed, 19 Nov 2025 08:00:10 +0200 In October, the European Parliament voted against the proposal for a new EU Forest Monitoring Law. However, work to harmonise forest data across Europe continues – and the Swedish University of Agricultural Sciences (SLU) plays an important role in that process. https://www.slu.se/en/news/2025/11/after-the-eu-rejection-of-the-forest-monitoring-law--european-cooperation-continues/ https://www.slu.se/en/news/2025/11/after-the-eu-rejection-of-the-forest-monitoring-law--european-cooperation-continues/ Tue, 11 Nov 2025 09:17:01 +0200 Most moose prefer to stay in young forests and mixed forests with a high proportion of deciduous trees. But they want to be far away from the nearest road. This is shown by a study from the Swedish University of Agricultural Sciences (SLU), which has mapped moose movements for over 20 years. https://www.slu.se/en/news/2025/11/how-moose-choose-to-move-in-forest-landscapes-avoiding-areas-close-to-roads/ https://www.slu.se/en/news/2025/11/how-moose-choose-to-move-in-forest-landscapes-avoiding-areas-close-to-roads/ Mon, 10 Nov 2025 08:31:12 +0200 For the first time, there is now a map showing where the forage for deer and moose is located. The maps, produced by researchers at SLU, shows where key tree species for ungulates are found and how much is at grazing height. https://www.slu.se/en/news/2025/10/heres-where-moose-and-deer-find-their-food--slu-releases-unique-map/ https://www.slu.se/en/news/2025/10/heres-where-moose-and-deer-find-their-food--slu-releases-unique-map/ Mon, 27 Oct 2025 07:52:06 +0200 The number of eels leaving the Swedish west coast to spawn in the Sargasso Sea has increased since eel fishing was closed in 2012. This is shown in a new study from the Swedish University of Agricultural Sciences (SLU), which for the first time evaluates the effects of the closure. https://www.slu.se/en/news/2025/10/local-fishing-closure-improved-european-eel-stock-on-the-swedish-west-coast/ https://www.slu.se/en/news/2025/10/local-fishing-closure-improved-european-eel-stock-on-the-swedish-west-coast/ Thu, 23 Oct 2025 12:54:14 +0200 Since the 80s, The Swedish University of Agricultural Sciences (SLU), the University of Gothenburg and the Swedish Museum of Natural History have monitored fish health, population status and contaminant levels in fish along the Swedish coast.
