“…The volume of deadwood was higher in the upland biotope than in the paludified biotope. This was in contrast to the finding of Jalonen and Vanha-Majamaa (2001) who reported that in paludified biotopes in mesic Picea abies stands, the volume of deadwood was higher than the average in managed stands. In the experimental study stands, the recent thinning activity increased the volume of deadwood in the upland biotope in the form of stumps and abundant logging waste such as crown tops (III).…”

“…Hannerz and Hånell (1997) found that most bryophytes retained or increased their cover seven to eight years after shelterwood logging in spruce forests in boreal Sweden. Jalonen and Vanha-Majamaa (2001), on the other hand, found that bryophytes decreased in singletree selection system felling (where 33% of the stand volume were felled) by the summer after the logging. However, in the same study, they did not find any change in species number or cover from pre-harvest conditions in residual forest patches in spruce forest in southern Finland.…”

Substrate form determines the fate of bryophytes in riparian buffer strips.Ecological Applications, http://dx.doi.org/10.1890/04-0570Access to the published version may require subscription. N.B. When citing this work, cite the original published paper. Abstract. Studies on the effectiveness of forest buffer strips left along streams after logging have long overlooked the biota of the buffers themselves, despite their high species richness. We investigated mosses and liverworts (bryophytes), abundant and species-rich groups in boreal forests, before and 2.5 years after logging along 15 small streams. In each site, two 1000-m 2 (20 ϫ 50 m) plots along the stream were inventoried; one plot in an area subjected to clear-cutting, and another in a buffer strip (10 m wide on each side of the stream). Ten plots along small streams in forest reserves in the same region were used as references. We found that less than half as many bryophyte species per plot disappeared after logging in the buffer strips compared to the clearcuts. The changes in bryophyte cover and in species composition were smaller in the buffer strips, and the species that were negatively affected in the clearcuts were less affected in the buffer strips. However, there was a significant change in species composition in the buffer strips compared to the references. Substrate form and taxonomic group were important factors in understanding this turnover. Many species growing on substrates with a convex form (e.g., logs, tree bases, and mesic ground) decreased or disappeared, while species on concave substrates were rather unaffected. This held for both mosses and liverworts, although liverworts were generally more sensitive than mosses. The difference in response of assemblages on convex vs. concave substrates makes changes in microclimate due to logging a likely explanation. The species in most need of protection (i.e., the red-listed species) were among the ones with strongest declines in the 20 m wide buffer strips. In order to function optimally for bryophyte conservation, forests along small streams need to be protected from high windthrow frequency and strong edge effects. Increasing the width of buffer strips at sites with known or potential values (e.g., large amounts of woody debris or boulders) should be considered a better strategy than using narrow buffer strips with a fixed width.

Wood fuel production has increased remarkably, but its environmental effects within the forest ecosystem have not yet been studied much. We investigated the immediate effects of two series of forest management treatments, which produce timber and forest chips, on the volume and decay classes of coarse woody debris (CWD). One of the treatment series included logging and residue harvesting (LRH) and mounding (M), while the other series included LRH and mounding combined with stump harvesting (MSH). We hypothesized that, i) LRH reduces CWD, excluding stumps; ii) the more intense the soil preparation treatment is, M vs. MSH, the more CWD is destroyed; iii) both LRH and soil preparation treatments (M and MSH) reduce the occurence of snags, highly decayed CWD and deciduous CWD in particular. Ten sample plots in mature managed Norway spruce (Picea abies (L.) H. Karst.) dominated forests were located in Southern Finland. The total volume of CWD on the sample plots was measured three times: before and after LRH, and after M or MSH. LRH significantly decreased the volume of snags and the combined volume of snags and logs. MSH significantly decreased the total volume of CWD, while M had no significant effect on the volume of CWD. The middle and highly decayed CWD were destroyed most easily in the treatments.
