“…McBride et al (1990) found EC a at red oak (Quercus rubra L.) sites to be strongly correlated with soil attributes associated with forest soil quality, such as exchangeable Ca, Mg and CEC. In a similar way, we have found a positive correlation between the field-measured soil EC a and concentrations of Ca, Mg and Na, but a negative correlation with Al in forest soils in Finnish Lapland (Närhi et al 2010b). With known distribution of geochemical elements in tills, the large quantity of measured soil EC a and SWC provides us with a justified basis to assess relative differences in micro-site soil regimes and natural recruitment of Norway spruce at intensively managed sites in Lapland.…”

“…They conjectured that soil degradation was coincidental with leaching of soil Ca and Mg. In addition, Närhi et al (2010b) have found a positive correlation between the field measured soil EC a and laboratory analyzed (plant available) Ca and Mg, whereas Al was negatively correlated to EC a . The reduction in the soil Ca and Mg supply caused by clear-cut and subsequent site preparation (Van Cleve and Dyrness 1983) significantly reduces the growth potential of shallow-rooted Norway spruce and contributes to low survival rate observed with the exposed mineral soil ( Fig.…”

The northern boreal forests in Fennoscandia have been managed for decades using clear-cut harvesting and subsequent mechanical site preparation (MSP). MSP is intended to reduce competing vegetation, improve soil temperature and water conditions as well as mobilize nutrients for the use by outplanted seedlings. The use of heavy machinery, particularly bulldozerdriven Marttiini-plough, has raised concerns about soil quality and therefore sustainability of forest productivity and forest floor diversity. We applied soil physical measurements and inventories of naturally established Norway spruce (Picea abies (L.) Karst.) to investigate these concerns 16-18 years after intensive forest management in Finnish Lapland. MSP with Marttiiniplough had inverted Podzol soil profile and created the following micro-sites: trench, tilt and untreated (UTR) soil between the ploughed tracks at former spruce sites. The soil electrical conductivity (EC a ) and soil solution conductivity (EC w ) at micro-sites of spruce seedling/ saplings, differed significantly (p<0.001). The majority of spruce individuals (60%) were established on UTR (mean EC a =0.54±0.34 mSm −1 ), while the proportion on tilt was minor (34%, EC a =0.35±0.18 mSm −1 ) and almost absent on trench (6%, EC a =0.12±0.11 mSm −1 ). In a similar way, the soil quality decreased such that EC wUTR = 11.7 ± 9.1mSm −1 > EC wTILT = 10.7 ± 9.2mSm −1 > EC wTRENCH = 2.2 ± 2.9mSm −1 . Spruce individuals at UTR (mean height 127±89 cm) and tilt (111±74 cm) were significantly (p<0.001) taller compared to those in trench (32±44 cm). The five study sites were surrounded by mature Norway spruce stands, yet only 0-14% of spruce seedlings/ saplings were found on the MSP-exposed mineral soil. These results imply that intensive forest practices result in losses in soil nutrient supply, hence endangering sustainability of the soil quality, and therefore occasionally hamper natural regeneration of Norway spruce.

It has been shown that the forest vegetation communities of Finnish Lapland are intimately related to soil chemistry; Ca-concentration being the major variable in determining plant diversity (Närhi et al 2011). For example, herb-rich forests grow in alkaline soils originated from Ca-rich rocks like dolomite and greenstones and many demanding calcifuge species colonize these fertile herb-rich forests (Kalliola 1973).…”

“…Finegrained till is more fertile than coarse-grained till and it has also a better water-retention capacity (Kalliola 1973;Sutinen et al 2011). The till composition is usually closely related to the bedrock composition of the area, since the rock materials were drifted rather short distances during last glacial period when till was formed (Koljonen and Tanskanen 1992;Kujansuu and Johansson 2005).…”

Effects of bedrock and surficial deposit composition on moose damage in young forest stands in Finnish LaplandRuuhola T., Nikula A., Nivala V., Nevalainen S., Matala J. (2016). Effects of bedrock and surficial deposit composition on moose damage in young forest stands in Finnish Lapland. Silva Fennica vol. 50 no. 3 article id 1565. 20 p. http://dx.doi.org/10.14214/sf.1565. Highlights• The effect of bedrock and soil on moose damage in forest plantations were examined.• Moose damage were concentrated in nutrient rich bedrock areas.• Bedrock of damaged stands contained a higher proportion of mafic and alkaline rocks.• Pine-dominated stands on fine grained fertile forest sites had the highest damage risk. AbstractThere is evidence that moose are attracted to fertile growth habitats apparently due to better quality and larger quantities of food. The nutrients in mineral soils originate from the weathering of bedrock and the composition of parental bedrock affects the fertility of produced mineral soil, thus affecting also the import of nutrients into the whole food web. We surveyed the connection between moose damage in forest plantations and the composition of bedrock and surficial deposits in Finnish Lapland. We used a database of compensated moose damage in private forests in years 1997−2010. Undamaged stands in National Forest Inventories (NFI) from years 1986-2008 served as a control data and moose-damaged NFI-stands as a reference data. Bedrock and surficial depositions and the location of studied stands in relation to ancient shorelines were explored by using the digital databases of the Geological Survey of Finland. Moose-damaged stands were concentrated in southwestern and east Lapland in the areas of the Peräpohja Schist Belt and Lapland's Greenstone Belt that are both composed of nutrient-rich rocks. The bedrock of damaged stands contained a higher proportion of mafic and alkaline rocks than did the control stands. Moose-damaged stands were pine-dominated and grew in more fertile forest sites than did control stands. Part of pine stands probably located in soils formerly occupied by spruce, which may increase the stands' vulnerability to biotic threats. Especially, there were relatively more moose damage in pine plantations regenerated on fine-grained mineral soils derived from nutrient rich rocks than in less fertile soils.
