“…Similar values were reported for Scots pine dominated forests from boreal Fennoscandia (Helmisaari, 1995). According to some recent studies, understory vegetation can also affect and modify nutrient flow in forest ecosystems (Rodenkirchen, 1995;Huber et al, 2004). It has been shown that grass understory vegetation can serve as an important sink of atmospheric nitrogen (Holub, 1999).…”

This paper presents data on species composition, biomass, and element pools (C, N, P, Ca, Mg, Na, K, Al, Fe, Mn) of the understory vegetation of spruce forests in the catchments of lakes Čertovo jezero (CT) and Plešné jezero (PL) in the Bohemian Forest (Šumava, Czech Republic). Calamagrostis villosa was the most abundant species in the CT catchment, while Vaccinium myrtillus was the most abundant species in the PL catchment. The catchments weighted mean (CWM) of above-ground biomass of the understory vegetation was 288 and 723 g m −2 in the CT and PL catchments, respectively. The significant difference in the biomass between the catchments was caused by the much higher abundance of V. myrtillus in the PL catchment. The CWM of below-ground biomass of the fine roots was 491 and 483 g m

“…However, as herbaceous plants have up to threefold higher nutrient concentrations than trees, the importance of the understorey vegetation for nutrient cycling is overproportionate to its biomass (Blank et al 1980;Yarie 1980;Rodenkirchen 1995;Mrotzek 1998;Bolte et al 2004;Muller 2003). Its importance even increases in disturbed systems such as clearcuts or windthrows, where the understorey vegetation becomes the most important ecosystem component in terms of primary production and nutrient uptake.…”

The estimation of aboveground biomass and nutrient pools of understorey plants in closed Norway spruce forests and on clearcuts

The estimation model PhytoCalc allows a nondestructive quantification of dry weight and nutrient pools of understorey plants in forests by using the relationship between species biomass, cover and mean shoot length. The model has been validated with independent samples in several German forest types and can be a useful tool in forest monitoring. However, in open areas within forests (e.g. clearcuts), the current model version underestimates biomass and produces unreliable nutrient pool estimations. Thus, tissue density, as approximated by leaf dry matter content (LDMC), is systematically higher under high light compared to low light conditions. We demonstrate that the ratio of LDMC under clearcut conditions to LDMC under forest conditions can be used to adjust the PhytoCalc model to clearcut conditions. We investigated the LDMC ratio of five exemplary species commonly occurring on clearcuts. Integrating the square of the ratio as a correction factor improved estimates of biomass to more than 70% fit between observations and predictions. Results also suggest this ratio can be used to correct nutrient concentrations modelled in PhytoCalc, which tend to be overestimated in clearcuts. As morphological groups of plant species exhibit significantly different ratios, we advise using group-specific correction factors for clearcut adjustments in the future.

“…The response of the ground vegetation has received less attention [5,6,25,35,36] though, in some cases, the ground flora contributes more to the annual nutrients cycling than the old trees [10,36]. Furthermore, if liming tends to be generalised, questions arise about the impact of this practice on the floristic composition, structure and diversity of plant communities [13].…”

-The objective of this study was to assess the effects of base cation (Ca, Mg, K) and phosphorous (P) fertilization on the vascular ground vegetation in mature European beech and sessile oak stands located on acid brown soils. Two types of treatment were applied next to control plots (dolomite lime, dolomite lime + natural phosphate + potassium sulphate). Specific richness, total cover (%), equitability coefficient as well as the Ecological Group of the ground vegetation were studied. Four years after dolomite application, new Ndemanding and ruderal species appeared and increased the specific richness. The natural phosphate application combined with potassium sulphate positively influenced the emergence of new mesotrophic plant species. In the beech stands the total cover tended to increase while in the oak stand the equitability coefficient decreased. The specific richness of the initial acidophilous vegetation remained unchanged but the total cover decreased. Differences between the response of the ground vegetation in the oak and the beech stands were attributed to a difference in stand density. base cation / phosphorous / acid brown soil / plant diversity / ecological group Résumé -Effets de la fertilisation sur les plantes vasculaires du sous-bois dans des peuplements de hêtre (Fagus sylvatica L.) et de chêne sessile (Quercus petraea (Matt.) Lieb.). L'objectif de cette étude est d'évaluer les effets d'une fertilisation en cations basiques (Ca, Mg, K) et P sur les plantes vasculaires du sous-bois dans des peuplements adultes de hêtre et de chêne sessile situés sur des sols bruns acides. Deux types de traitement ont été appliqués et comparés à un témoin (dolomie, dolomie + phosphate naturel + sulfate de potassium). La richesse spécifique, le recouvrement total, le coefficient d'équitabilité ainsi que les groupes écologiques de la végétation au sol ont été étudiés. Quatre ans après l'application de dolomie, de nouvelles espèces nitrophiles et rudérales apparaissent, augmentant ainsi la richesse spécifique. Le phosphate naturel combiné au sulfate de potassium influence positivement l'émergence de nouvelles espè-ces mésophiles. Dans les peuplements de hêtre, le recouvrement total tend à s'accroître et dans le peuplement de chêne le coefficient d'équitabilité diminue. La richesse spécifique de la végétation initiale acidophile reste inchangée mais le recouvrement total diminue. Des différences entre la réponse de la végétation au sol dans les peuplements de chêne et de hêtre ont été mises en évidence et ont été attribuées à la différence de densité de peuplement. cation basique / phosphore / sol brun acide / diversité floristique / groupe écologique Ann.
