Atte Komonen, Panu Halme, Mari Jäntti, Tuuli Koskela, Janne S. Kotiaho, Tero Toivanen. (2014). Created substrates do not fully mimic natural substrates in restoration: the occurrence of polypores on spruce logs. Silva Fennica vol. 48 no. 1 article id 980. https://doi.org/10.14214/sf.980
Highlights: Polypore communities were more homogeneous among created than among natural logs; The old-growth forest indicator Phellinus ferrugineofuscus occurred frequently on natural logs, but occupied only a few created logs; Results show that created logs do not fully mimic natural logs.
Many protected areas have been under intensive forest management prior to protection and thus lack natural ecosystem structures and dynamics. Dead wood is a key structure in forests harboring hundreds of threatened species. We investigated the ecological success of dead wood creation as a boreal forest restoration measure. We analysed whether the polypore communities of chain-saw felled and girdled (subsequently fallen) Norway spruce (Picea abies (L.) H. Karst.) logs differ from naturally formed spruce logs of similar decay stage and size. The study was conducted in Leivonmäki National Park in central Finland 8 years after the restoration measures. The average number of polypore species was highest on the chain-saw felled logs and most of the common polypore species were most frequent on this substrate. However, among the natural logs, number of species increased more steeply with increasing number of logs, suggesting greater variation in community composition on this substrate. The old-growth forest indicator Phellinus ferrugineofuscus occurred frequently on natural logs, occupied a few girdled logs but was absent from chain-saw felled logs. Our results show that from the polypore perspective created logs do not fully mimic natural logs, suggesting that creating substrates for species may pose a challenge for restoration.

Kaarlo Linkola. (1926). Suunnitelma luonnonsuojelualueiden erottamiseksi Pohjois-Suomen valtionmailla. Silva Fennica no. 1 article id 4434. https://doi.org/10.14214/sf.a8382
English title: Plan for establishment of protected areas in state-owned lands of Northern Finland.

The article gives a proposal for areas that would be suitable for protected areas, situated in state-owned lands in Northern Finland. Eight areas are described in the article, namely Oulankajoki area in Northern Kuusamo, Kutsajoki area in Kuolajärvi, Pyhätunturi in Kemijärvi, Pisavaara in Rovaniemi, Pallastunturi and Ounastunturi area, Malla fells in Kilpisjärvi, Pääskyspahta area in Petsamo and Heinäsaari in Petsamo.

Each of the areas possess special features in Finnish nature, samples of which should be reserved in pristine state. Furthermore, costs of the protection are small. The resident population is, however, in general against protection. The protection should therefore be organized in a way that minimizes the disadvantages caused by limitations to land use, for example grazing, reindeer husbandry, fishing and hunting.

According to Finnish Nature Conservation Act, all wildlife in the conservation areas should be protected. Protection of wolverine and wolf is, however, difficult because of the damages they cause for domestic animals. Protection of bear is regarded to be possible in most of the proposed protected areas.
