Effects of management and restoration on forest biodiversity: an experimental approach
2004
To conserve biodiversity of boreal forests, many management and restoration actions have been undertaken during the last decades. However, research based knowledge about the impacts of the currently used practices are yet largely unavailable. Here we introduce two large scale experiments on the impacts of forest management and restoration on biodiversity of boreal forests. In the first experiment we concentrate on the effects of prescribed burning on species richness of two species groups, which are known to be largely dependent on the amount and quality of decaying wood: saproxylic beetles and polypore fungi. In the second experiment, we study the immediate surroundings of small forest bro…
Social impacts of biodiversity offsetting: A review
2022
Biodiversity offsetting is the widely studied last step of the mitigation hierarchy. Despite numerous studies and the methodological development completed for biodiversity calculations, the human aspect remains unsolved. Biodiversity conservation is typically governed at national or state levels, but the harm caused to biodiversity as well as people occurs locally. In biodiversity offsetting, biodiversity values can be relocated far from the original area, but relocating the values people hold regarding their nearby nature may not be possible. Acknowledging the local people's hopes and values may further complicate biodiversity offsetting, therefore it emphasises even more the need to avoid…

Ecology, environmental requirements and conservation of corticioid fungi occupying small diameter dead wood
2016
The increasing human impact upon the biosphere of earth is causing profound changes across all spatial scales. The ability to cope with human-induced disturbance varies among organisms; specialist species are more negatively affected than generalist species. Forests are among the most heavily affected ecosystems; especially the dead wood associated organisms are in peril. The earlier research has strongly focused on large diameter dead wood and associated species. The aim of this thesis was to investigate small diameter dead wood and collect systematic information about species richness and abundance as well as habitat and substrate preferences of associated corticioid fungi. Fungal data wa…
Long-term impacts of increased timber harvests on ecosystem services and biodiversity : A scenario study based on national forest inventory data
2020
The transition to a climate-neutral economy is expected to increase future timber demands and endanger the multifunctionality of forests. National scenario analyses are needed to determine long-term forest management impacts and support forest policy making in defining guidelines for the sustainable provision of forests’ ecosystem services and biodiversity (ESB). Using national forestry inventory data, the forest management model MASSIMO and a model to estimate harvesting costs, we simulated forest development in Switzerland under five politically relevant timber harvesting scenarios until 2106 (business as usual and four increased timber mobilisation scenarios). Model results were analysed…
Tale(s) of a forest – re-creation of a primeval forest in three environmental narratives
2020
We analyze three environmentally conscious works that are concerned with the state of Finnish forests: the documentary film Metsän tarina/Tale of a Forest (2012), the book with the same name (2013) and the series of short documentaries Tarinoita metsästä/Tales from the Forest (2013). By combining methods from arts research and ecology, we ask how the narratives adapt material from nature photography. The film and book present mythic stories and old Finnish beliefs about forests. They also contain references to cultural memory. Additionally, the biodiversity on display reflects a conventional practice to exhibit large or charismatic species. However, the ecological message remains only impli…
