- This synthesis report is a meta-analysis of perspectives for biodiversity and ecosystems, with a strong focus on human impacts on the environment, and a work order to enable and manage the protection, survival and evolution of all species on Earth. The goal is to protect nature without any further species loss (Zero Extinction). With this report, we assess alarming signals from the environment; determine the needs of threatened biota and the required actions to manage and protect landscapes and ecosystems; and identify some inescapable tendencies, challenges but also possibilities. The story of humans on Earth is at a critical juncture. Human behaviour is inherently dependent on physical and societal relations, including orientation and positioning within the physical environment. There is no single cultural benefit that is independent of provisioning through ecosystem services. Humans are part of the environment, acquire all needs from it and, as such, depend on its integrity and management for life and well-being. Moreover, if human impacts to the environment continue to increase the risk of rebound effects impacting human life and health will increase as well. Whenever a biome, ecosystem, habitat or species is heavily impacted or threatened with irreversible transformation or extinction, prevailing environmental conditions are relevant and should be observed, analysed and remedied as necessary and where possible. Ecology examines the evolutionary, historical and more recent interplay between biological life and the abiotic environment, while the role of social science and the humanities is to question the physical and social landscape, and how and why it should be protected or influenced, e.g. by nature conservation measures under political and economic, ethical and legal considerations. Thus, for all inter-relationships between natural and sociocultural processes, a joint venture in the form of social-ecological thinking is necessary to combine natural sciences and the humanities. With this contribution, we combine ecological knowledge with social science knowledge (s.l.) through the participation of scientists of many different disciplines. We analyse history and current processes to assess risks, threats and possibilities, and call for an array of regulations and measures that can contribute to halting of biodiversity loss and that assist in achieving a sustainable future. Regulations comprise creativity, cultural incentives, social norms, environmental education and economic investments—such as payments for sustainable agriculture, forestry, and fishery; investments in water, soil and air purity; and much clearer and stronger legal restrictions and consequences around waste streams and environmental degradation. Moreover, a gradual change from profit-oriented economies in the short-run to environmentally-sensitive policies that include systematic environmental programmes in the long term might help to decrease pressure on ecosystems and biota. Such economics might also include the real costs of consumerism, including the impacts of particular products on the environment and on human health. The greatest hurdle for the continued existence of many critically endangered species is the impact of widespread anthropogenic-driven change in the usage of water, air and land, and industry intensification in agriculture, aquaculture, forestry, urbanisation, transportation and mining sectors. However, there is not one simple solution to solve these issues. We conclude that many of the current developments have to be adjusted or gradually altered in a step-wise manner, especially with respect to existing sociocultural behaviours. Therefore, various concepts, decisions and measures should be discussed and implemented at all scales from local to supranational and among researchers, practitioners and politicians.

- Question: When evaluating forests in terms of their biodiversity, distinctiveness and naturalness, the affinity of the constituent species to forests is a crucial parameter. Here we ask to what extent are vascular plant species associated with forests, and does species’ affinity to forests vary between European regions?Location: Temperate and boreal forest biome of Northwestern and Central Europe. Methods: We compiled EuForPlant, a new extensive list of forest vascular plant spe- cies in 24 regions spread across 13 European countries using vegetation databases and expert knowledge. Species were region-specifically classified into four categories reflecting the degree of their affinity to forest habitats: 1.1, species of forest interiors; 1.2, species of forest edges and forest openings; 2.1, species that can be found in forest as well as open vegetation; and 2.2, species that can be found partly in forest, but mainly in open vegetation. An additional “O” category was distinguished, covering species typical for non-forest vegetation.Results: EuForPlant comprises 1,726 species, including 1,437 herb-layer species, 159 shrubs, 107 trees, 19 lianas and 4 epiphytic parasites. Across regions, generalist forest species (with 450 and 777 species classified as 2.1 and 2.2, respectively) significantly outnumbered specialist forest species (with 250 and 137 species classified as 1.1 and 1.2, respectively). Even though the degree of shifting between the categories of for- est affinity among regions was relatively low (on average, 17.5%), about one-third of the forest species (especially 1.2 and 2.2) swapped categories in at least one of the study regions.Conclusions: The proposed list can be used widely in vegetation science and global change ecology related to forest biodiversity and community dynamics. Shifting of forest affinity among regions emphasizes the importance of a continental-scale forest plant species list with regional specificity.
