  • Synergies and trade-offs between biodiversity and distance to settlements in the spatial allocation of wind power
    Luukkonen, Saara; Räsänen, Aleksi; Koivula, Matti; Tolvanen, Anne
    Journal of environmental management (Academic Press, 2026)
    The need to phase out fossil energy has promoted a rapid development of wind power, yet this development may negatively affect biodiversity and encounter resistance among local citizens. To study whether optimal locations for wind power differ when considering biodiversity impacts or distance to settlements, we used spatial suitability analysis for allocating wind power in Pirkanmaa region in southern Finland. We clustered high-suitability areas using Anselin Local Moran's I cluster analysis to find spatially contiguous areas for wind power. We compared the results of biodiversity-based and settlement-based allocation in three scenarios for electricity production for the year 2035: the Minimum scenario corresponded to the current production-consumption ratio in the region, the Self-sufficiency scenario to regional electricity self-sufficiency, and the Maximum scenario to the maximum production capacity. The most suitable locations for wind power were forested areas in the sparsely populated parts of the region. Optimal locations for biodiversity-based and settlement-based suitability showed only partial overlap, suggesting trade-offs in wind power allocation. The overlap area increased from 0% in the Minimum scenario to 41% in the Maximum scenario. The total area of the highly suitable locations based on both biodiversity and distance to settlements was not sufficient to cover the production capacity in the Self-sufficiency scenario, indicating that reaching electricity self-sufficiency may not be possible without compromising biodiversity or distance to settlements. The results highlight the importance of considering both biodiversity values and human well-being in wind power development, as potential for conflicts in wind power development is likely to increase with growing electricity demand in the future.

    Boreal forests are important reservoirs of biodiversity, carbon and timber stocks. However, timber harvest can alter biodiversity in these forests without clear evidence on the duration needed for biotic groups to recover. Resilience of boreal forest biodiversity to clear-cut harvest was examined with a meta-analysis of 190 datasets from boreal and hemi-boreal forests of Europe/Russia and North America for arthropods, birds, small mammals, lichens, bryophytes and vascular plants. We modelled similarity of community composition between harvested and unharvested stands versus years post harvest. In approximately half of cases, predicted times for recovery to pre-harvest composition were ≤30 years. In other cases, recovery took much longer or had not occurred within the timeframe of our data; for example, in conifer forest: >100 years (bryophytes), >55 years (small mammals), ~95 years (lichens) and ~85 years (vascular plants). Saproxylic beetles showed no resilience within the 16 (conifer forest) or 29 (mixed forest) years post harvest for which we had data. Recovery generally took longer in conifer and mixed than in broadleaf forests, which always showed either resistance (bryophytes, vascular plants) or resilience with recovery within 12–25 years. Conserving biodiversity in boreal forests will require extended rotations, management for ‘old forest’ structural elements and areas protected from harvesting.
  • First record of brown spot needle blight (BSNB) caused by Lecanosticta acicola on Pinus mugo in Finland
    Terhonen, Eeva; Trifković, Miloš; Poimala, Anna
    Journal of plant diseases and protection : 3 (Springer Nature, 2026)
    Climate change has already been acknowledged to have destabilizing effects on tree health. In addition to increased abiotic disturbances, trees are increasingly negatively impacted by the emergence of fungal pathogens. Lecanosticta acicola, the causal agent of brown spot needle blight (BSNB), affects pines and is considered invasive in Europe. In October 2025, typical symptoms of L. acicola, brown circumferential lesions with a yellow halo, were observed on an urban tree, Pinus mugo. The pathogen was isolated from surface-sterilized needles, and morphological and molecular identification confirmed it as L. acicola. Here, we report the first observation of the invasive pathogen L. acicola on the non-native host P. mugo in Finland. Lecanosticta acicola is classified as a Quality Plant Pest by the Finnish Food Authority and as no suitable plant protection methods are currently available in Finland, this finding is of particular significance. The detection of this pathogen highlights a potential threat to forestry and emphasizes the need for preventive strategies to limit its spread, including eradication, breeding and improved integrated pest management (IPM) practices in nurseries.

    Agricultural and Food Science : No. 2 (The Scientific Agricultural Society of Finland, 2026)
    Solution-oriented approaches are crucial for identifying the leverage points to promote sustainable management of agricultural peatlands in Finland. This study used a living lab approach to co-create policy measures and actions to mitigate and reduce greenhouse gas emissions from drained agricultural peatlands. This study contributed to narrowing the gap between high-level sustainability ambitions and their practical implementation by demonstrating how a living lab can operationalise transdisciplinary collaboration in a contested land-use context. The living lab required collaboration between different scientific domains and the wider society by including interdisciplinary scientists and practitioners from outside academia. The living lab enabled mutual learning processes between science and society to promote a shared understanding between science and society for the co-creation of acceptable solutions and transition pathways. The dichotomy between the cultivation of drained peatlands for food production and the urgent need to mitigate climate change by reducing greenhouse gas emissions could be solved by targeting interventions or leverage points that can change mind sets and values regarding the importance of productive peat fields in producing food to ensure food and nutrition security, farmers’ livelihood, and rural vitality in Finland. Restructuring agricultural policies in Finland as well as in the EU could be easier if there is a shared perception between science and society that removing drained peat fields from cultivation would not threaten these key aspects. This study revealed conditional openness among farmers to reduce cultivation on less productive peat soils if adequate incentives are provided, therefore resistance to change is not absolute but closely tied to concerns over fairness, livelihoods, and regional viability, thus highlighting the importance of just transition measures.

    Aim: To understand species population ecology, we need to study how trends of demographic drivers change over time and space, especially so under current rapid climate change. However, knowledge on long-term trends of survival and productivity, especially using multiple species over large spatial scales, is scarce. Here, we examined the long-term trends of adult survival and productivity of European songbirds, their relation to temperature gradients within species' ranges, and different traits across multiple species over large spatial scales. Location: Ten countries in Europe. Time Period: 2001–2021. Major Taxa Studied: 28 songbird species. Methods: We used bird ringing data from the European Constant Effort Ringing scheme (CES), with 1.2 million captures of birds. We investigated the long-term trends of adult survival and productivity in relation to temperature gradients within species' ranges. We also tested differences in the long-term trends of demographic measures in relation to species' migratory strategies (long-distance migrants vs. short-distance migrants and residents) and long-term population trends. Results: There was no apparent major change in the long-term trends of either adult survival or productivity, and they did not show differences along the range gradient. Long-term trends of productivity differed between migratory strategies: long-distance migrants showed more negative trends in productivity than short-distance migrants and residents, while survival trends were similar between the two groups. Trends in both adult survival and productivity had equal positive connections with the population trends of songbirds.Main ConclusionsThe difference in long-term trends of productivity between migratory strategies highlights the importance of different conservation efforts for long-distance migrants compared to short-distance or resident birds.
