European forests might not be realizing their full potential

European forest managers can have their cake and eat it, because according to a new study maximizing timber production in a forest does not necessarily have to come at a cost of reduced species diversity or the capacity to regulate climate change by the same forest. However, as the international research team, among them scientists from Senckenberg Research Institute and Natural History Museum and the University of Leipzig, point out, most European forests fall well below their possible maximum levels of these three capacities. The study was published recently in Ecology Letters.

Throughout Europe forests are usually managed with one or two major objectives. These are typically timber production, climate regulation or conservation. But this focused approach might not be necessary as trade-offs among different ecosystem processes that contribute to achieving these major three forest management objectives are relatively rare, a newly published study an international research team shows.

“One might think there is a conflict between timber production and biodiversity conservation. For example, in some cases planting trees very densely to increase timber yields might lessen understorey plant diversity or bird diversity, both important components of biodiversity conservation” explains Dr. Peter Manning, part of the research team from the Senckenberg Biodiversity and Climate Research Centre. “However overall, we found that this is the exception, not the rule; such winner-loser games are not what is really happening.”

To find out what goes on in European forests the researchers measured and correlated 28 ecosystem services and processes that underpin timber production, climate regulation and species diversity in six regions including Finland, Poland, German, Romania and Italy. They are all part of FunDivEurope, a large-scale project examining the relationships between biodiversity and ecosystem functions in forests. The group also analyzed data from national forest inventories across Europe, making the study one of the most comprehensive analyses of forest ecosystem functioning at this scale to date.

“The results show that there are synergies between ecosystem processes. For example, if the forest fares well for timber production this also means the forest makes a positive contribution to climate regulation, as tree growth also means more carbon stored” says Dr. Fons van der Plas, a researcher at University of Leipzig, who conducted the study whilst working at the Senckenberg Biodiversity and Climate Research Centre. Additionally, the researchers found, that if a forest does a good job of producing timber and regulating the climate, then this combination may go hand in hand with high levels of species diversity in the same forest.

But the potential for these newly found synergies is not capitalized on by forest managers. Currently there only a few spots throughout Europe where researchers could find simultaneous high levels of all the ecosystem processes that contribute to timber production, climate regulation and biodiversity conservation. Compared to these sites, most forests meet only half of this potential.

In light of this the researchers call for changes in forest management strategies in order to maximize ecosystem processes and thus maximize the benefits of European forests. But those new strategies have yet to be identified, as Manning quickly points out: “The next step would be to have a closer look at the few spots with a high amount of synergies between different ecosystems services to see how this works and might be transferred to other sites”.

Warmer springs can actually reduce overall plant growth, study finds

An extensive study on the effects of warmer springs on plant growth in northern regions shows substantially reduced plant productivity in later months.


Ecological impact of logging in the Białowieża Forest extends far beyond logged areas

A team of researchers from the Swedish University of Agricultural Sciences, Siedlce University and the Mammal Research Institute Polish Academy of Sciences, has provided a first objective estimate of the extent of logging (since 2015) in the renowned Białowieża Forest. This forest is the last remaining area of lowland temperate forest with a primeval character in Europe and is a UNESCO World Heritage and Natura 2000 site.


Global warming increases wildfire potential damages in Mediterranean Europe

A study published in Nature Communications, led by researchers of the University of Barcelona in collaboration with other research institutions, shows that anthropogenic warming will increase the burned areas due fires in Mediterranean Europe, and the increase of the burned area could be reduced by limiting global warming to 1.5 ºC. The higher the warming level is, the larger the increase of the burned area is.
