“…Moreover, the spatial repartition of this species shows that local acidity can occur even in the limed plots and thus the soil spatial heterogeneity observed here can highly influence fungal community structure. A similar liming-induced reduction of the abundance of acidophilic species at the profit of ubiquist, neutrophilic or competitive ones was observed on forest ground vegetation (Hallbäcken and Zhang, 1998) and mosses (Dulière et al, 2000). In the same way, high-dose liming decreased germination of acidophilic plant species (such as Vaccinium myrtillus) but increased germination of widespread ones (Primula veris, Senecio sylvaticus) (Olsson and Kellner, 2002).…”

Abstract• Liming is a forestry practice used to counteract forest decline in acidic soils. It consists of direct Ca and Mg input to forest soil, which restores tree mineral nutrition, but also modifies microbial communities in soil. The aim of this study was to assess the effects of liming on both belowground (ectomycorrhizal root tips) and aboveground (epigeous sporocarps) fungal communities.• Results showed that the modification of soil chemical properties (pH, and Ca-Mg contents versus total free Al and Fe concentrations) was a stronger factor of ECM community structuring than tree host. The species appearing in limed plots were ubiquist or known as good competitors and replaced acidophilic and stress species.• At the sporocarp level, tree host was a stronger factor of community structuring than soil chemical properties associated with liming. On the whole, there was a shift in the community composition from a typical acidophilic forest fungal community of medium altitude in the untreated plots to a less typical one, with the reduced dominance of acidophilic fungi while many late-stage forest species appeared.• We finally suggest a marker species (Russula ochroleuca) to assess both above and belowground effects of liming on ectomycorrhizal communities.

Il consiste en un apport direct de Ca et Mg au sol forestier, ce qui restaure la nutrition minérale de l'arbre, mais aussi modifie les communautés microbiennes du sol. Cette étude évalue les effets du chaulage sur les communautés fongiques hypogées (apex ectomycorrhiziens : « ECM ») et épigées (carpophores).• Les résultats montrent que la modification des des propriétés chimiques du sol (pH et concentrations en Ca-Mg échangeables versus concentrations en Al et Fe échangeables) est un facteur de structuration de la communauté d'ECMs plus fort que l'arbre hôte. Les espèces qui sont apparues dans les placeaux chaulés sont ubiquistes ou compétitrices et ont remplacé des espèces acidophiles ou connues pour être associées à des conditions de stress.• Concernant les carpophores, l'arbre hôte est un facteur de structuration de la communauté plus fort que les propriétés chimiques du sol associées au chaulage. Dans l'ensemble, on a observé une modification de la communauté fongique, passant d'une communauté typique de forêt acide de moyenne altitude dans les placeaux témoins vers une autre moins spécifique, caractérisée par une moindre dominance d'espèces acidophiles et l'apparition de nombreuses espèces de forêt mature.• Nous suggérons enfin une espèce marqueur (Russula ochroleuca) qui permet d'évaluer facilement les effets du chaulage sur les communautés de champignons mycorrhiziens, aussi bien du point de vue des apex mycorrhiziens que des carpophores.

“…In conifer forests in Europe, an increase in grasses such as D. Jexuosa and herbs such as chickweed wintergreen (Trienntalis europaea) has been documented in response to fertilization with N or N plus lime (Nams et al, 1993;Kellner and Redbo-Torstensson, 1995;Hallbacken and Zhang, 1998). Nitrogen additions to boreal spruce stands resulted in increases in nitrophilous species, such as D. Jlexuosa, and decreases in dwarf shrubs, such as Vhccinium spp., and other ericaceous plants (Mitka, 1987;Kellner and Redbo-Torstenssen, 1995;Pitcairn et al, 1998) through altered competitive relationships.…”

“…There is a potential risk of nitrogen leaching to surrounding surface waters if the nitrification process is stimulated and excess nitrate is produced . Also, if the dynamics of the nitrogen cycle is changed the species composition of the field vegetation and tree growth might be affected (Andersson, Hallbäcken, & Popovic, 1996;Hallbäcken & Zhang, 1998). In the past, nitrogen leaching after liming has been observed in areas with high deposition of nitrogen or forest soils rich in nitrogen (Johansson, Nilsson, & Olsson, 1999).…”

Recovery of Acidified Streams in Forests Treated by Total Catchment Liming

Reduced emissions of acidifying pollutants have changed the acidification process, and as a result, forest soils and surface waters are slowly recovering in Sweden. However, model calculations show that some areas may never recover completely unless further measures, such as liming, are undertaken. Liming of surface waters (lakes, rivers and wetlands) has been successfully practised in Sweden since the 1970s, but repeated treatments are necessary. A full recovery of acidified lakes and streams without frequent liming is however not possible until soil acidification is reversed in the most strongly affected areas. In this study, the recovery of acidified streams was examined using 'the total catchment approach' i.e. treatment of both recharge and discharge areas. The aim was to compare the quantitative effect of different treatments on run off chemistry and the recovery of brown trout. Catchments in southwest Sweden were treated with a combination of 2 tons of wood ash and 4, 6 or 12 tons of crushed limestone per hectare in 1998/1999. Treatment of both recharge and discharge areas resulted in fast and significant changes in stream water quality, e.g. increased concentrations of calcium, higher pH and ANC and a decreased concentration of inorganic aluminium. The initial changes were dependent on the distribution of the applied lime between discharge and recharge areas rather than the average dose on the total catchment. Treatment of recharge areas only, resulted in smaller but still significant effects on calcium, pH and ANC in stream water. Furthermore, there was an initial leaching of nitrate but it was only minor compared with the elevated leaching that occurs after a clear-cut. As a result of the treatments, brown trout is now successfully reproducing.
