Road verges provide alternative habitats for some, but not all, meadow plants
Questions Agricultural intensification has led to the decline of biodiverse meadows and other semi-natural grasslands. Road verges offer potential alternative habitats for meadow species, but they may not be suitable for all meadow species due to different soil properties, frequent disturbances, pollution or suboptimal management. Are the communities of vascular plants and bryophytes similar or dissimilar to those in mown or grazed meadows? What kind of species are associated with road verges, mown meadows or grazed meadows? How do the habitat types differ in their soil conditions and disturbance intensity? Location The study was conducted on 36 sites in Central Finland. Methods We compared…

Semi-natural habitats in the European boreal region: Caught in the socio-ecological extinction vortex?
AbstractWe propose to consider semi-natural habitats—hotspots for biodiversity—being caught in a socio-ecological extinction vortex, similar to the phenomenon described for species threatened with extinction. These habitats are essentially socioecological systems, in which socioeconomic drivers are interlinked with ecological processes. We identify four highly interlinked and mutually reinforcing socio-economic processes, pertaining to the importance of semi-natural habitats for (i) agricultural production, (ii) policy, research and development; (iii) vocational education in the fields of agricultural sciences and (iv) public’s experiences with semi-natural habitats. Evidence from six count…
Key advantages of the leverage points perspective to shape human-nature relations
This perspective paper synthesises the special issue 'Human-nature connectedness as a leverage point for sustainability transformation'. Based on the articles in this special issue, we aim to foster the operationalisation of the leverage points perspective to shape human-nature relations to enable sustainability transformations. Specifically, we draw on four key advantages of the leverage points perspective: (i) the explicit recognition of deep leverage points; (ii) the ability to examine the interactions between shallow and deep system changes; (iii) the combination of causal and teleological modes of research; and (iv) the ability to function as a methodological boundary object. The contr…
Extinction risk indices for measuring and promoting planetary well-being
The concept of planetary well-being, which stresses the persistence of lineages in ecosystems, is intimately linked to species extinction risk. Avoiding extinctions is a moral issue, as wiping out the outcomes of eons of evolutionary history and their future potential is clearly unconscionable. The concept of planetary well-being is also systemic: It is understood that species, as integral parts of ecosystems, are vital for the well-being of all systems on Earth. Yet, despite international agreements to protect biodiversity, global biodiversity loss and ecosystem degradation has continued unimpeded over the past decades. We review the role of goals and targets in the UN Convention on Biolog…

Multitaxa species richness of a wood-pasture complex in the Finnish SW-archipelago
Traditional rural biotopes such as semi-natural grasslands and wood-pastures are among the most threatened biotopes in Finland. Archipelago Sea area hosts an especially representative collection of these biotopes, considering both their combined area and average quality. We surveyed birds, vascular plants, bryophytes, polypores and ground-inhabiting stipitate macrofungi in one wood-pasture complex in Korppoo, Archipelago Sea area. Here we report and discuss the results of these surveys. We detected altogether 457 species, including 8 red-listed bird species and 6 red-listed vascular plant species. We didn´t detect any red-listed bryophytes or fungi, but also these groups included several ra…
Systematic targeting of management actions as a tool to enhance conservation of traditional rural biotopes
Traditional rural biotopes (TRBs), which are biologically and culturally valuable habitats maintained by low-intensity grazing and mowing, are a core element of biodiversity in Europe. During the last decades, TRBs have faced severe habitat loss and fragmentation due to agricultural modernization. Despite their well-known critical state, their conservation remains inadequate, thus raising a need to advance TRB conservation via spatial land-use planning. In this study we analyze a national GIS database on TRBs in order to examine how the current TRB network can be complemented in terms of conservation value based on known ecological characteristics. Given different target scenarios for the a…
Semi-natural habitats in boreal Europe: a rise of a social-ecological research agenda
The European continent contains substantial areas of semi-natural habitats, mostly grasslands, which are among the most endangered habitats in Europe. Their continued existence depends on some form of human activity, for either production or conservation purposes, or both. We examined the share of semi-natural grasslands within the general grassland areas in boreal Europe. We reviewed research literature across the region to compile evidence on semi-natural grasslands and other semi-natural habitats, such as wooded pastures, in respect to a range of topics such as ecology, land-use change, socioeconomics, and production. We also explored drivers of the research agenda and outlined future re…
Current agri-environmental policies dismiss varied perceptions and discourses on management of traditional rural biotopes
Abstract Traditional rural biotopes (TRBs) are threatened habitats that host significant biodiversity and several ecosystem services, and depend on active management such as low-intensity grazing. The current study explores private landowners’ decision-making on TRB management and abandonment within a social-ecological system framework. We provide insight into supporting resilience of TRB systems in the face of agricultural modernization. Using a mixed methods approach with content analysis and Q analysis, we demonstrate that TRB management fosters cultural, biological, aesthetic, and utilitarian values. These are reflected in different ways through conservationist’s, profit-oriented farmer…
Do allopatric maleCalopteryx virgodamselflies learn species recognition?
There is a growing amount of empirical evidence that premating reproductive isolation of two closely related species can be reinforced by natural selection arising from avoidance of maladaptive hybridization. However, as an alternative for this popular reinforcement theory, it has been suggested that learning to prefer conspecifics or to discriminate heterospecifics could cause a similar pattern of reinforced premating isolation, but this possibility is much less studied. Here, we report results of a field experiment in which we examined (i) whether allopatric Calopteryx virgo damselfly males that have not encountered heterospecific females of the congener C. splendens initially show discri…
Alternative reproductive tactics and the propensity of hybridization
One explanation for hybridization between species is the fitness benefits it occasionally confers to the hybridizing individuals. This explanation is possible in species that have evolved alternative male reproductive tactics: individuals with inferior tactics might be more prone to hybridization provided it increases their reproductive success and fitness. Here we experimentally tested whether the propensity of hybridization in the wild depends on male reproductive tactic in Calopteryx splendens damselflies. Counter to our expectation, it was males adopting the superior reproductive tactic (territoriality) that had greatest propensity to hybridize than males adopting the inferior tactics (…
Conservation of traditional rural biotopes in Finland : a social-ecological approach
This research focuses on conservation of traditional rural biotopes, which are biodiverse meadows and wood-pastures that are dependent on management through grazing or mowing. These low-intensity management actions have become rare as a result of agricultural modernisation. I have utilised a social-ecological approach in order to seek for the most critical factors hindering conservation of traditional rural biotopes in Finland. I also explore practical solutions that have the potential to improve their conservation status. The coverage of traditional rural biotopes has faced severe habitat loss during the last 150 years. This has led to endangerment of several habitat types and species that…
Grazing and soil pH are biodiversity drivers of vascular plants and bryophytes in boreal wood-pastures
Abstract Wood-pastures have been formed by traditional low-intensity livestock grazing in wooded areas. They host high biodiversity values that are now threatened by both management abandonment (ceased grazing) and agricultural intensification, and therefore these habitats are of conservation interest in Europe. In order to explore the effects of grazing on the biodiversity of boreal wood-pastures, we studied the communities of vascular plants and bryophytes in 24 currently grazed and 24 abandoned sites. In addition to the current management situation, we studied the effects of soil pH and moisture, tree density, historical land-use intensity, time since abandonment (in abandoned sites) and…
Pathways towards a sustainable future envisioned by early-career conservation researchers
Scientists have warned decision-makers about the severe consequences of the global environmental crisis since the 1970s. Yet ecological degradation continues and little has been done to address climate change. We investigated early-career conservation researchers' (ECR) perspectives on, and prioritization of, actions furthering sustainability. We conducted a survey (n = 67) and an interactive workshop (n = 35) for ECR attendees of the 5th European Congress of Conservation Biology (2018). Building on these data and discussions, we identified ongoing and forthcoming advances in conservation science. These include increased transdisciplinarity, science communication, advocacy in conservati…
A landscape approach to planetary well-being
“Landscape” refers to a perceivable spatial level shaped by socio-ecological interactions and represents the systems where people live. Human societies have globally transformed landscapes to meet their needs, e.g., nutrition or shelter, according to cultural preferences. This human domination of land has resulted in considerable competition for space with other lifeforms, driving biodiversity loss through land-use change and intensification, as well as coming into conflict with planetary well-being. Recent research has highlighted the relevance of the landscape level when articulating human activities with and in their environment and maintaining human and nonhuman cohabitation. Indeed, th…
Planetary well-being
Tensions between the well-being of present humans, future humans, and nonhuman nature manifest in social protests and political and academic debates over the future of Earth. The increasing consumption of natural resources no longer increases, let alone equalizes, human well-being, but has led to the current ecological crisis and harms both human and nonhuman well-being. While the crisis has been acknowledged, the existing conceptual frameworks are in some respects ill-equipped to address the crisis in a way that would link the resolving of the crisis with the pivotal aim of promoting equal well-being. The shortcomings of the existing concepts in this respect relate to anthropocentric norma…

The Importance of Engaging Local People in Landscape Management – Experiences from an EU Project
“Bull by the Horns” -project initiated landscape management and promoted biodiversity associated with diminishing High Nature Value farmland habitats in Finland. A specific focus was on grazed semi-natural grasslands and wood-pastures which are collectively referred to as traditional rural biotopes (TRBs). Collaboration among project workers, non-farming landowners, and cattle owners reintroduced grazing to abandoned pastures, and management was financed through agri-environmental payments. Using adaptive co-management principles, the project enabled collective definition of integrated site-specific management objectives. A better understanding of contemporary challenges and opportunities t…

Ecological and economic consequences of aggregating conservation sites and multiuse forests
Intensive forest management has fragmented forest landscapes and decreased biodiversity and crucial ecosystem services. Current conservation and management efforts have not been sufficient and more efficient landscape level planning is needed to maintain biodiversity and ecosystem services in forest landscapes. One efficient way to improve the species survival and the maintenance of multiple benefits in forest landscapes may be applying an approach where a part (e.g. third or half) of the total area is managed as multiuse landscapes within which e.g. a third of the area is be protected [third-of-third (1), or third-of-half (2)]. Aggregated networks of protected habitats are expected to safe…
