“…Thomas et al [34] explained about 80% of the variability in stream pH and ANC by soil types and catchment area in streams draining catchment type I. This is better than the 34% of variability explained in this study using rainfall and catchment area.…”

“…Other statistical analyses of large regional data sets have shown significant relationships between streamwater chemistry and some complex environmental factors, such as altitude and relief [24,32], catchment size [37], glacial influence [10,27], soil base saturation [5], land use [15] or some combination of these factors [11,12,19,21,22,31,34]. Surprisingly, the primary effect of precipitation amount was not often directly highlighted [16,36].…”

“…They showed that atmospheric deposition of acid and acidifying compounds were the main sources of acidity at high altitude in the northern part of the massif where the acid load was relatively high, whereas forest harvest contributed up to 50% to soil acidification in the south-western piedmont, relatively protected * Corresponding author: dambrine@nancy.inra.fr from acid atmospheric deposition [13]. Environmental factors influencing streamwater acidity were analyzed by Thomas et al [34] in 100 catchments of the sandstone area, using a large spatially distributed dataset describing environmental factors. Stream pH and ANC were successfully predicted using soil types, the catchment area and the relative surface and stratigraphic position of the different sandstone types in the catchment.…”

-The influence of sandstone composition, precipitation, vegetation and relief on streamwater composition at base flow was studied in 95 forested catchments located in the sandstone part of the Vosges Mountains (N.E. France). Catchments lie on four main types of sandstone. Information was acquired for each catchment using a geographic information system (GIS) and spatially distributed databases. Sulphate concentration is mainly negatively correlated to the annual rainfall and positively to the relative area covered by conifers in the catchment. Nitrate is positively correlated to altitude. Sodium, Cl and Si concentrations are strongly inter-correlated and negatively related to the annual precipitation and the relative area of the conglomerate layer in the catchment. Calcium, Mg, ANC (Acid Neutralising Capacity) and pH are negatively correlated to precipitation, and positively correlated to the relative area of the sandstone layer containing dolomitic nodules. This study emphasizes the role of annual rainfall amounts in controlling stream chemistry at base flow.streamwater / acidification / spatial analysis / Vosges / sandstone Résumé -Facteurs environnementaux influençant la composition chimique des eaux sur substrats gréseux dans les Vosges. L'influence de la composition chimique des grès, des précipitations, de la végétation et du relief sur la composition chimique des ruisseaux en étiage a été étudiée dans 95 bassins versants des Vosges en utilisant un système d'information géographique (SIG) et des bases de données géo-référencées. La concentration en sulfates est corrélée négativement avec les précipitations moyennes annuelles et positivement avec la surface relative couverte par les résineux dans le bassin. Les nitrates sont positivement corrélés avec l'altitude. Le sodium, le chlorure et la silice sont fortement inter-corrélés et sont négativement liées aux précipitations et à la surface relative du conglomérat dans le bassin. Le calcium, le magnésium, l'ANC et pH sont négativement corrélés aux précipitations, et positivement corrélés avec la surface relative occupée par le grès de Senones, qui contient des nodules dolomitiques. L'étude souligne le rôle des précipitations annuelles sur la composition chimique des eaux en étiage. chimie des eaux / acidification / analyse spatiale / Vosges / grès

“…The conclusions of some earlier studies on forest decline as to the absence of clear influence of site conditions on forest health must therefore be taken with caution as already stated earlier [15]. A spatial approach relying on a "classical" geographic database remains nevertheless very interesting; it helps testing and upscaling the results from a few research sites and allows defining critical thresholds and mapping zones at risk [20,21,22].…”

Relation between ecological conditions and fir decline in a sandstone region of the Vosges mountains (northeastern France)

-The present study re-examines the influence of ecological conditions on the health of silver fir (Abies alba) measured in 1989, during the so-called forest decline crisis, in the sandstone portion of the Vosges mountains, on the basis of an assessment of almost 3000 forest management units (10-20 ha each). Relationships between defoliation and needle yellowing (related to Mg deficiency) and environmental factors were analysed with contingency tables and modelled using discriminant functions. The results confirmed the predominant influence of altitude and stand age; these two factors explain 70% of the spatial variability of defoliation and 64% of that of yellowing. In addition, a database composed of 178 soil analytical profiles was analysed in relation to the geographic database. The commonly used variable "altitude" appeared to combine the influence of several related variables which are crucial for the biological functioning of the tree: especially the plant available water holding capacity and chemical characteristics were negatively correlated with elevation in the study area. This ecological feature is likely to be common to a number of mid-elevation mountain range in Europe and was often neglected in the earlier studies on forest decline. forest decline / Abies alba / GIS / spatial analysis / discriminant analysis / Vosges mountains Résumé -Relations entre les conditions écologiques et le dépérissement du sapin dans les Vosges gréseuses (France).Ce travail réexamine l'influence des conditions écologiques sur le dépérissement du sapin, mesuré lors de la crise du dépérissement forestier dans les Vosges, sur la base d'une notation exhaustive de 3 000 parcelles forestières (10-20 ha) gérées par l'Office National des Forêts dans les Vosges gréseuses. Les relations entre défoliation et jaunissement des aiguilles (généralement dû à une carence en Mg) et les conditions environnementales moyennes de chaque parcelle ont été étudiées par des tableaux de contingence, et modélisées en utilisant une analyse discriminante. L'altitude et l'âge des peuplements expliquent respectivement 70 % de la défoliation et 64 % du jaunissement. Le paramètre « altitude » combine de nombreux facteurs influençant le fonctionnement physiologique de l'arbre. En utilisant une base de données de 178 profils pédologiques, nous montrons que l'altitude est négativement corrélée à la réserve utile des sols et au taux de saturation, indépendamment du type de grès. Ce type de distribution est probablement assez banale dans un certain nombre de moyennes montagnes européennes, et forme un biais souvent négligé dans les études de dépérissement. dépérissement forestier / Abies alba / SIG / analyse spatiale / analyse discriminante / Vosges Ann.
