Over the course of the COVID-19 pandemic we have begun to reshape the way we think about many things including our work lives, social lives, and health. But what about biodiversity? After weeks of facing the same view from our home office, some of us have started to notice the biodiversity of our gardens and become avid new birdwatchers, running to grab our binoculars whenever we see a new species. Others have started visiting the forest more often and have found peace and comfort in the biodiversity it offers. However, the link between biodiversity and the COVID-19 crisis is much larger than what goes on in our backyards. With the theme of biodiversity, this World Environment Day urges us to address this link and take urgent action in order to safeguard the diversity of life on the planet, and ultimately our own.
Peaceful, tranquil, calm, still: these are all adjectives we might use to describe a walk in the forest. However, the forests we walk in may not always be the picture of serenity we imagine them to be. Behind the scenes some foresters are igniting explosives, firing guns at trees, decapitating ancient giants with chainsaws, and committing other disturbing acts that would make us tree-huggers quick to defend our beloved darlings. However, what we don’t know is that these fierce and seemingly cruel acts are doing just that, defending our forests against harm. It is not a battle against them, but rather a battle for them: the battle to bring back biodiversity.

“Deadwood has a major role for the conservation of saproxylic species and contributes to carbon sequestration, nutrient supply, natural regeneration and protection against falling rocks.” (Lachat et al., 2013:92)*
A substantial amount of literature on the importance of deadwood in Central European forests has been available providing partial recommendations to enhance deadwood-dependent biodiversity. However, a comprehensive review of science- and forestry experts-based recommendations effectively enhancing deadwood bearing in mind operational implications has not been presented in international literature.
Global biodiversity is decreasing at an alarming pace. It occurs in remote wilderness areas but also right at our doorsteps. Nature is everywhere, and it is facing a global crisis. As such, the PopUp Forest movement is activating a civic response to locally address biodiversity loss and drive momentum towards the UN2020 Convention on Biological Diversity.
This event, to be held in China, will gather representatives from 190 countries to reaffirm their commitment to nature. Its positive outcome is of great importance to steer the political decision-making process regarding biodiversity degradation.

International climate action and therefore climate negotiations are not only about fossil fuels. Forest conservation or forestations became strategies that are (sometimes more and sometimes less) acknowledged around the globe and strategies that are here to stay. The Paris Agreement promotes forest management as a pathway towards halting climate change through the reduction of CO2 emissions. At the end of the climate negotiations, more than 50 countries have pledged to protect existing forests and add tree cover in order to reduce greenhouse gas emissions. However, things might not be that simple.
Science writer and reporter Gabriel Popkin recently released an article in NATURE with the provocative title “How much can forests fight climate change?”. In his text, he examines several studies arguing that trees do not only influence the climate in one direction. Planting trees in order to take more carbon out of the atmosphere is a highly practical way to combat climate change – as long as the trees are planted in the right place. In boreal forests for instance, forests do cool the climate, so reforestation there is one crucial and applied way to meet the climate goals. However, the question how big of a role forest have in fighting climate change is at the same time diverse and complex. Although forests suck carbon dioxide from the air, they also affect the climate in various ways. For example, trees absorb and reflect light differently. The light-green broadleaves reflect more sunlight back to the atmosphere than the dark conifers and therefore have more cooling effect during the summer. All the trees emit chemical compounds that affect the climate in different ways: some cool the climate, some make it warmer. Planting trees in tundra might not be efficient when aiming at cooling the climate.
Planting trees is a longstanding traditional urban planning approach for improving liveability in cities. Dating back from the earliest urban societies such as the Roman Empire, urban planners have applied trees for bringing shade, mitigating temperature, rainfall and wind, and providing food and fodder for animals. Providing urban trees, parks and urban forests is probably one of the earliest applications of what is now termed “nature-based solutions”. Nature-based solutions are defined by the International Union for Conservation of Nature (IUCN) as “actions to protect, sustainably manage, and restore natural or modified ecosystems, that address societal challenges effectively and adaptively, simultaneously providing human well-being and biodiversity benefits”.
How does the Danish Nature Agency address the trend of rewilding? What are the plans to transition managed forests into forest biodiversity reserves in Denmark – and what are the expected benefits and challenges? We discussed these and other questions with Mogens Krog, Deputy forest officer at the Danish Nature Agency.
Mogens, rewilding is a trend in Denmark now – who are the ones who argue for large connected wild nature areas and no further management? And what is the approach of the Danish Nature Agency?
In Denmark there is a growing interest among nature conservationists and nature conservation NGO’s for large connected wild nature with large herbivores (plant eater). A large area in a Danish context is considered to be 500 ha. Some argue for re-introduction of species which have been part of nature in Denmark in pre-historic time, e.g. wild horses, European bison, moose, and even elephants. Others find domestic animals such as cattle and horses, sufficient to create natural disturbances in nature areas for the benefit of biodiversity.
Denmark is a much regulated landscape with agriculture covering more than 60 % of the land area. Therefore, it may be relative expensive to include private land in rewilding projects Also, in order to avoid major conflicts with agricultural interests, rewilding is likely to be limited to large fences. State owned land is the focus of rewilding interests. In Denmark, state owned land is primarily managed by the Danish Nature Agency under the Ministry of the Environment and Food and covers app. 5% of the total land area in Denmark (210.000 ha).
The European project Spurring INnovations for forest eCosystem sERvices in Europe (SINCERE) is officially launched. SINCERE is a four year project on the variety of ecosystem services provided to people by our forests. Funded through the European Union’s Horizon 2020 research and innovation programme and coordinated by the European Forest Institute, the project aims at contributing to a potential foundation for a new European forest related policy.
SINCERE is all about ecosystem services related to forests – with a focus on but not limited to European forests. Ecosystem Services in short are goods and services which benefit society. They are multifaceted and reveal themselves in many ways – from economic over material to health and emotional contributions. You can check out our introductory video for a more detailed explanation.
While you may immediately think of carbon sinks, water cycle and wood biomass, forests are also associated with cultural and spiritual benefits.
Nature is the diversity of living organisms on Earth. It constitutes an essential element for human well-being and for ecosystems services (such as food production, water cycles, soil fertility).
In Europe several studies have demonstrated a steady loss of animal and plant species related to forest, caused for example by intensive land use, invasive alien species introduction, pollution and global warming (EEA short report on Biodiversity, 2008). Maintenance of biodiversity in forests will support its resilience to natural and human pressures. It contributes for example to the mitigation of raising temperatures and to food security.
I have recently been working on several mandatory and voluntary tools supporting nature conservation in forests, and I would like to introduce some of the most important here.
Discussing solutions and searching for more resilience forests
How are different European countries dealing with bark beetle outbreaks and which role do questions like sanitary cutting, monitoring systems, forest ownership, windstorms and expectations towards nature conservation play? What are the challenges regarding climate change? How do the social perception of active and inactive forest management impact forester’s activities in local forests? Which tools should be used to cope with natural disturbances and how we can educate foresters, policy makers, and other relevant stakeholders? Following the invitation of the Polish Ministry of Environment and the Polish State Forests, we discussed these and more issues in the Białowieża Forest during a working seminar of the European Network INTEGRATE from 25-27 June 2018.
