“…In 2016, Sweden and Finland accounted for 30% of all roundwood production among the EU28 (Eurostat, 2020). Even-aged management with clear-cutting is a common practice in all three countries, with considerable impacts on biodiversity and ecosystem services (Savilaakso et al, 2019).…”

This study examines the role of business organizations in co-governing biodiversity and ecosystem services (BES) using a phenomenon-based approach and bridging business management literature, ecosystem services literature and environmental governance literature. The empirical analysis includes twelve Nordic forest corporations considered market leaders in Finland, Sweden and Norway. Using content analysis of corporate sustainability reports and managerial interviews, we recorded 127 company-led measures addressing BES and we categorized them into seventeen types (e.g., land use planning and restoration, mobilization of financial resources for conservation, partner auditing, capacity building and consultation with stakeholders). For each BES measure, we also identified the BES issues being addressed (e.g., climate regulation, soil maintenance, cultural values); company motivation (i.e., compliance, strategic, profit-seeking); the stakeholders/beneficiaries involved (e.g., employees, forest owners, experts, local communities, public administration, NGOs); and the private governance instruments used for implementing the measure (i.e., regulatory, economic, information and rights-based instruments). The findings suggest that practices such as monetary valuation, biodiversity offsets and green bonds are emerging as profitable or strategically interesting options for Nordic forest companies. However, well-established practices, such as forest inventory, partner auditing and land sparing, continue to be the backbone of private BES governance among the leading companies examined. Although not directly motivated by compliance, private governance measures are largely nested in legislation. The contribution of this study includes reflections of relevance for both the scholarly and managerial realms. From a scholarly perspective, we further elaborate an understanding of BES management and governance from an organizational perspective. From a managerial perspective, we provide and discuss an overview of potential measures that forest companies can implement to address biodiversity and other socio-ecological issues at the land-use level.

Timber harvest may impact tick-borne disease by affecting small mammal and tick community structures. We assessed tick and small mammal populations in older second-growth redwood (Sequoia sempervirens (D. Don) Endl) habitat at two harvested sites in Santa Cruz County, California, where local risk of tick-borne disease is high and determined the prevalence of tick-borne pathogens in ticks. After single-tree removal harvest in 2014, there was a modest reduction in canopy, primarily toward the end of the study. Harvested sites showed strong reductions in California mouse (Peromyscus californicus, (Gambel)) captures 2-yr after harvest, resolving such that treatments and controls were comparable by the end of the study. Following harvest, treated sites experienced a transient decreased tick infestation while control plots experienced an increase. Ixodes angustus (Neumann) infestation probability on harvested plots decreased immediately after harvest, increasing with time but remaining lower than control plots, whereas I. pacificus (Cooley and Kohls) prevalence was higher shortly after the harvest on harvested plots, and continued to increase. Mean abundance of ticks on vegetation increased on control plots. We detected Borrelia burgdorferi ((Johnson et al.) Baranton) and Anaplasma phagocytophilum ((Foggie 1949) Dumler) in 3.8 and 3.1% of ticks on rodents, but no differences were associated with harvest. Impacts of forest harvest on tick-borne disease depend on removal practice and intensity, whether or not hosts are habitat specialists, and whether or not ticks are host specialists.

What are the effects of even-aged and uneven-aged forest management on boreal forest biodiversity in Fennoscandia and European Russia? A systematic review

Background Forest harvesting changes forest habitat and impacts forest dependent species. Uneven-aged management is often considered better for biodiversity than even-aged management, but there is an ongoing discourse over the benefits and disadvantages of different silvicultural systems. This systematic review contributes to the public discussion and provides evidence for policy making by synthesising current evidence on impacts of even-aged and uneven-aged forest management on biodiversity in boreal forests of Fennoscandia and European Russia. In this review even-aged and uneven-aged forest management are compared directly to each other as well as to natural forest to provide a broad basis for public discussion. Methods Both peer-reviewed and grey literature were searched in bibliographical databases, organizational webpages and internet search engines in English, Finnish, Swedish and Russian. Articles were screened for relevance by their title/abstract and again by full text. The inclusion of studies was assessed against pre-defined criteria published in an a priori protocol. A narrative synthesis and meta-analysis were conducted to describe the evidence base and to compare species richness and abundance between differently managed forests. The influence of habitat specialism, taxon, years since harvesting, deadwood availability and harvesting intensity on species richness and abundance were also tested. Review findings Searching identified 43,621 articles of which 137 articles with 854 studies had independent data and were included in the narrative synthesis. Of those, 547 studies were included in the meta-analysis. The most studied taxa were arthropods, vascular plants, bryophytes, fungi, and lichens. Results showed that forests with less disturbance (uneven-aged and mature even-aged) host more forest dependent species than young even-aged forests (< 80 years old) although the difference was only marginally significant for mature even-aged forests (> 80 years old). Uneven-aged forest had similar number of species and individuals than natural forest whereas even-aged forest had less species than natural forest. Open habitat species and their individuals were more numerous in young even-aged forests and forests undergone retention harvest. Effect sizes found were mostly large indicating strong and uniform impact of forest management based on species’ habitat preferences. In addition to habitat specialism, years since harvest explained some of the differences found in species richness and abundance due to increase of open habitat species in the early successional stages and forest dependent species in late successional stages. Taxon had limited explanatory power. Conclusions Habitat preferences determine species’ response to different harvesting methods and the magnitude of effect is large. Less disturbance from harvesting is better for forest dependent species whereas opposite is true for open habitat species. Uneven-aged and mature even-aged forests (> 80 years old) are important to maintain biodiversity in boreal forests. However, the results also highlight that natural forests are needed to ensure the future of forest dependent species in Fennoscandia and European Russia. Given that a broader set of biodiversity aspects are to be protected, best overall biodiversity impacts for a variety of species at landscape level can be achieved by ensuring that there is a mosaic of different forests within landscapes.
