Animal welfare concern and perception of nature shape nature users’ support for large herbivore rewilding in Denmark
Ecosystem restoration strategies, such as rewilding and the introduction of large herbivores, are promising approaches that can promote and preserve biodiversity. However, lack of public support can hinder their implementation. We use the case of rewilding in Denmark to measure people’s support for (re-)introducing large herbivores and how support is influenced by participants’ characteristics, perspectives and exposure to photographs of large he…

Ten Strategies to Promote Climate Resilience and Sustainability of Global Forests
Climate change and escalating human pressures erode the resilience of global forests, putting biodiversity, carbon storage, and societal well‐being at risk. Fragmented, single‐sector responses cannot keep pace with the speed or complexity of these threats. By synthesizing insights from resilience theory and global practices across ecological, social, and institutional dimensions, we propose 10 mutually reinforcing strategies that together provide…
Identifying conservation gaps
International biodiversity policies call for protecting 30% of land and sea by 2030, requiring countries to demonstrate genuine progress toward this target. The pan-European Natura 2000 network of protected areas is currently considered to contribute by default. However, without rigorous assessments of protection effectiveness, official statistics risk substantially overestimating progress and undermining the target. Here, we introduce a science-…
From open landscapes to forest refugia
The red deer ( Cervus elaphus ) is one of the few remnant species of the European Pleistocene megafauna. It occupies a wide range of habitats across the Holarctic, yet the factors shaping the species’ realized ecological niche over time remain poorly understood. To investigate these dynamics, we analysed published stable carbon and nitrogen isotope data from 623 bone collagen samples spanning 21,000 years in Europe. The δ 13 C values, considered …
Global trends in urban forest irrigation
Urban forests are critical for climate adaptation and liveability, but effective irrigation management—key to their sustainability—remains poorly documented at the global scale. This study addresses this critical knowledge gap by analysing urban forest irrigation practices across 109 cities in 21 countries, offering one of the first global assessments of irrigation approaches, challenges, and opportunities. Using survey data, we examined water so…
Expanding the Resist–Accept–Direct framework for developing nature‐based solutions and societal adaptations to biological invasions
Biological invasions threaten biodiversity and human well‐being, making invasive species management a global necessity. Despite substantial investments in engineering‐based management approaches, preventing invasions is becoming harder with rising species introductions. Additionally, widespread use of a few control methods raises ethical concerns, demands long‐term human control over natural ecosystems and risks unintended socio‐ecological impact…
Transforming forest management through rewilding
Forests are crucial for biodiversity, climate stability, and human well-being, yet rising pressures from climate change and conventional forestry practices threaten their resilience and sustainability. Approximately 30% of global forests are managed intensively, often as monoculture plantations, compromising biodiversity conservation, carbon sequestration, and ecosystem stability. Here, we propose integrating rewilding-inspired forestry as a tran…
Socioecological risks amplified by rising plant invasions in India
Pathway narratives towards a nature-positive European Union land system
The Nature Futures Framework (NFF) aims to open up space for plural perspectives on human–nature relationships and to identify visions for people to navigate towards desirable nature-positive futures. Operationalising the NFF offers a way to explore alternative pathways to reach these futures, but such applications are currently underdeveloped. Normative narratives can describe pathways towards nature-positive futures based on environmental polic…

Green spaces provide substantial but unequal urban cooling globally
Climate warming disproportionately impacts countries in the Global South by increasing extreme heat exposure. However, geographic disparities in adaptation capacity are unclear. Here, we assess global inequality in green spaces, which urban residents critically rely on to mitigate outdoor heat stress. We use remote sensing data to quantify daytime cooling by urban greenery in the warm seasons across the ~500 largest cities globally. We show a str…
Post-fire recovery of vegetation in the Chornobyl Radiation and Ecological Biosphere Reserve
Fires significantly affect the structure and diversity of vegetation. Natural recovery of vegetation after fires in the Chornobyl Exclusion Zone is of special interest because of its status as a nuclear disaster area. This is the first assessment of the potential for natural regrowth of forest and post-fire succession after the catastrophic fires of 2020 that scorched 62 000 ha of forest across the territory. Most of these areas (>80%) have high …
Defining the Anthropocene as a geological epoch captures human impacts’ triphasic nature to empower science and action
Unmanaged naturally regenerating forests approach intact forest canopy structure but are susceptible to climate and human stress
Maintaining newly re-established forests is an important policy and challenge for ecosystem restoration and climate-change mitigation. However, a global assessment of canopy structure in regenerating forests under different management and whether they are developing toward that of intact forests is lacking, impeding the understanding of their roles in carbon cycling and biodiversity recovery. Here we present the first near-global assessment of re…
Ginnerup Revisited. New Excavations at a Key Neolithic Site on Djursland, Denmark
New excavations of an enclosure-related site at Ginnerup on Djursland, Denmark, in 2020 resulted in the identification of several features containing depositions of marine shells. One of these, A4, is a natural depression with a fill comprised of four consecutively deposited layers, forming an undisturbed stratigraphy, dated by several 14C dates to between c. 3150 and 2950 BC. The oldest layer contained finds from phase MN A Ib of the Funnel Beak…
Tree cover and its heterogeneity in natural ecosystems is linked to large herbivore biomass globally
Addressing intertwined crises of climate change and biodiversity loss is a pressing global challenge, with trees playing pivotal roles in promoting carbon sequestration and habitat diversity. However, there is a distinct knowledge gap concerning the global drivers shaping tree cover and its heterogeneity, particularly the roles and relative importance of large herbivores and fire compared to climatic and topo-edaphic conditions. Here, we deploy s…
Quantifying the human cost of global warming
The costs of climate change are often estimated in monetary terms, but this raises ethical issues. Here we express them in terms of numbers of people left outside the ‘human climate niche’—defined as the historically highly conserved distribution of relative human population density with respect to mean annual temperature. We show that climate change has already put ~9% of people (>600 million) outside this niche. By end-of-century (2080–2100), c…

Megafauna extinctions in the late-Quaternary are linked to human range expansion, not climate change
The Earth has lost approximately half of its large mammal species (≥45 kg, one-third of species ≥9 kg) over the past 120,000 years, resulting in depauperate megafauna communities worldwide. Despite substantial interest and debate for over a century, the reasons for these exceptionally high extinction rates and major transformation of the biosphere remain contested. The predominant explanations are climate change, hunting by modern humans (Homo sa…

Tracking Hunter-Gatherer Impact on Vegetation in Last Interglacial and Holocene Europe
We review palaeoenvironmental proxies and combinations of these relevant for understanding hunter-gatherer niche construction activities in pre-agricultural Europe. Our approach consists of two steps: (1) identify the possible range of hunter-gatherer impacts on landscapes based on ethnographic studies; (2) evaluate proxies possibly reflecting these impacts for both the Eemian (Last Interglacial, Middle Palaeolithic) and the Early–Middle Holocene…
People have shaped most of terrestrial nature for at least 12,000 years
Significance The current biodiversity crisis is often depicted as a struggle to preserve untouched habitats. Here, we combine global maps of human populations and land use over the past 12,000 y with current biodiversity data to show that nearly three quarters of terrestrial nature has long been shaped by diverse histories of human habitation and use by Indigenous and traditional peoples. With rare exceptions, current biodiversity losses are caus…
Ecosystem restoration through aerial seeding
Understanding the driving factors of soil multifunctionality is of great significance for the protection and restoration of degraded terrestrial ecosystems. However, the effects of above‐ and belowground factors are rarely evaluated simultaneously, and the driving mode of both factors on soil multifunctionality is not clear. Here, we evaluated the restoration of mobile dunes threatened by desertification through aerial seeding, that is, the sowin…

Trophic Rewilding Advancement in Anthropogenically Impacted Landscapes (TRAAIL)
A variety of rewilding initiatives are being implemented across Europe, generally characterized by a more functionalist approach to nature management compared to the classic compositional approach. To address the increasing need for a framework to support implementation of rewilding in practical management, we present TRAAIL-Trophic Rewilding Advancement in Anthropogenically Impacted Landscapes. TRAAIL has been co-produced with managers and other…
Site‐specific modulators control how geophysical and socio‐technical drivers shape land use and land cover
Human utilisation of natural resources is the most important direct driver of land cover patterns in the Anthropocene. Here, we present a conceptual framework for how the effects of geophysical drivers (e.g., topography, soil, climate, and hydrology) and socio‐technical drivers (e.g., technology, legal regulation, economy, and culture) on land use and land cover are shaped by site‐specific modulators such as local topography and social and cultur…

It is often claimed that changes in material culture signify adaptations to changing environments. Deploying novel conceptual models and computational techniques, research funded by the European Research Council seeks to reconstruct the patterns and processes of cultural transmission and adaptation at the turbulent transition from the Pleistocene to the Holocene
Changing NPP consumption patterns in the Holocene
There have been vast changes in how net primary production (NPP) has been consumed by humans and animals through the Holocene. Here we ask: how much NPP energy may have become available following the megafauna extinctions? When did humans, through agriculture and livestock, consume more NPP than wild mammals? When did humans and wild mammals use more energy than was available in total NPP in each country? The megafauna extinctions potentially lib…

Geospatial patterns in traditional knowledge serve in assessing intellectual property rights and benefit-sharing in northwest South America
Our region-wide analysis highlights the geospatial complexity in traditional knowledge patterns, underscoring the need for improved geographic insight into the ownership of traditional knowledge in areas where biocultural diversity is high. This high geographic complexity needs consideration when designing property right protocols, and calls for countrywide compilation efforts as much localized knowledge remains unrecorded
Science for a wilder Anthropocene
Trophic rewilding is an ecological restoration strategy that uses species introductions to restore top-down trophic interactions and associated trophic cascades to promote self-regulating biodiverse ecosystems. Given the importance of large animals in trophic cascades and their widespread losses and resulting trophic downgrading, it often focuses on restoring functional megafaunas. Trophic rewilding is increasingly being implemented for conservat…

Rewilding complex ecosystems
Facilitating “wildness” Humans have encroached upon a majority of Earth's lands. The current extinction crisis is a testament to human impacts on wilderness. If there is any hope of retaining a biodiverse planetary system, we must begin to learn how to coexist with, and leave space for, other species. The practice of “rewilding” has emerged as a method for returning wild lands, and wildness, to landscapes we have altered. Perino et al. review thi…
Residential green space in childhood is associated with lower risk of psychiatric disorders from adolescence into adulthood
Urban residence is associated with a higher risk of some psychiatric disorders, but the underlying drivers remain unknown. There is increasing evidence that the level of exposure to natural environments impacts mental health, but few large-scale epidemiological studies have assessed the general existence and importance of such associations. Here, we investigate the prospective association between green space and mental health in the Danish popula…

Analogous losses of large animals and trees, socio‐ecological consequences, and an integrative framework for rewilding‐based megabiota restoration
Large‐sized animals (megafauna) and trees (megatrees) are key ecosystem components with high cultural and economic importance going back millennia. Once common, both groups of megabiota have been massively reduced in pre‐historic and historic times, with human‐induced downsizing still ongoing. Key ecosystem services provided by megafauna and megatrees include nutrient and seed transfer, carbon allocation, climate regulation and biodiversity facil…
Rewilding should be central to global restoration efforts
Rewilding should be central to the massive restoration efforts needed to overcome the global biodiversity crisis and enhancing the biosphere’s capacity to mitigate climate change. Key elements include large areas for nature, restoration of functional megafaunas and other natural biodiversity-promoting factors, synergy with major societal dynamics, and careful socio-ecological implementation
