Most European forests are used for timber production. Given the limited extent of unmanaged (and especially primary) forests, it is essential to include commercial in conservation forest biodiversity. In order develop ecologically sustainable management practices, important understand impacts on forest-dwelling organisms. Experiments allow testing effects alternative strategies, and monitoring multiple taxa informs us response range across To provide a representative picture currently...
Riparian forests surrounding streams host high biodiversity values, but are threatened by clear-cut logging. Narrow buffer strips of about 15 m commonly left between the stream and clear-cut, studies suggest that width should be at least 30 to protect riparian plant communities. Moreover, selective logging is often allowed on in order increase economic gain. We used an experiment 43 sites where strip within were manipulated supplemented with unlogged control sites. report short-term changes...
Urbanisation and biodiversity loss in urban sprawling areas diminish human-nature interactions, which could hinder nature conservation initiatives (Soga & Gaston, 2026). To evaluate whether a more biodiverse greenspace promotes we developed survey to explore attitudes towards lawns meadows among residents of the Helsinki metropolitan area.About 70% respondents were willing participate transforming lawn into meadow. Consequently, six transformed via voluntary participation...
Green-tree retention is a forest management method in which some living trees are left on logged area. The aim to offer 'lifeboats' support species immediately after logging and provide microhabitats during re-establishment. Several studies have shown immediate decline bryophyte diversity thus questioned the effectiveness of this method, but longer term lacking. Here we studied epiphytic bryophytes European aspen (Populus tremula L.) along 30-year chronosequence. We compared flora 102...
Abstract Questions How does the presence of grazers impact plant diversity at various spatial scales? What are effects on β‐diversity and its two components, species turnover nestedness? Are caused by defoliation, trampling or defecating? Location Twenty‐four currently grazed 24 abandoned wood‐pasture sites in Central Finland. Methods The richness vascular plants bryophytes was studied four scales: within 4‐m 2 subplots (α 1 ), 100‐m plots 3 ) landscape (γ). β‐Diversity between (β ). Results...
Habitat loss is a major threat to biodiversity. It can create temporal lags in decline of species relation destruction habitat coverage. Plant specialized semi-natural grasslands, especially meadows, often express such extinction debt. We studied and fragmentation meadows examined whether the changes meadow coverage had caused an debt on vascular plants. also historical or present landscape patterns contemporary environmental factors were more important determinants occurrence. surveyed...
Preserving streamside forest habitats or buffer strips is considered to reduce forestry-related biodiversity loss in commercial landscapes. However, it still unclear what type of management and near forests can be undertaken without compromising their natural change through succession. Using a before–after, control–impact study design, we tested the impacts forested (15 30 m wide, with selective logging), preserved after clear-cutting, on changes polypore communities boreal Finland....
Wood-pastures are threatened anthropogenic biotopes that provide habitat for an extensive group of species. Here we studied the effect management, grazing intensity, time since abandonment, historical land-use soil properties and stand conditions on communities saprotrophic fungi in wood-pastures Central Finland. We found proportion broadleaved trees pH major drivers these boreal wood-pastures. In addition, tree species richness, moisture, intensity abandonment affected fungi. Current...
Abstract 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 all species due different soil properties, frequent disturbances, pollution or suboptimal management. Are their communities vascular plants bryophytes similar dissimilar those in mown grazed meadows? What kind are associated with road verges, How do habitat types differ...
The microclimate of streamside habitats are protected from the effects logging with buffer strips retained trees. However, these often narrow due to their financial loss. Wider, selectively logged buffers might protect while providing same economic return. This study investigates on and growth bryophyte Hylocomium splendens two buffers: a standard unlogged (∼15 m) wider (∼30 decreasing intensity towards stream. was conducted in Central Finland eight sites where were next each other....
This study reports the bryophyte flora of Lågskär, an isolated lighthouse island in Åland province Finland. A total 81 species were found on including 74 moss and seven liverwort species. Syntrichia ruraliformis is reported for first time Finland, whereas Ceratodon conicus was believed to be extinct Finland Brachythecium turgidum considered regionally from southern
Ihmiskuntana hyvinvointimme on täysin riippuvaista luonnon monimuotoisuudesta – lukemattomista muista lajeista ja niiden elinympäristöistä. Elämän yhteenkietoutuneisuus sen arvo itsessään vaatii meiltä kohtuullisuutta luonnonvarojen hyödyntämisessä. Perimmäinen syy niin monimuotoisuuden ehtymiselle kuin ilmastonmuutokselle elämäntapamme, joka kannustaa kasvavaan kulutukseen, jota globaalisti kasvava väestö edelleen ruokkii1 .
