Nitrogen and drought effects on the tree-soil interaction of ECM and AM temperate trees

Soil texture, soil physicochemical properties and climatic data from the PhytOakmeter plot DKr (Kreinitz, Germany)

PhytOakmeter (www.phytoakmeter.de) is a field platform using the Quercus robur oak clone DF159 outplanted since 2010. This platform is used to monitor the impact of climate change and land use management on the "soil - plant - interactor" complex. Sites from PhytOakmeter are located either in forest or grassland habitats and represent a wide range of environmental contexts with specific stressors. All sites are equipped with loggers measuring air and soil temperature and soil moisture. Soil cores have been collected to analyze their chemical and physical characteristic. The DKr plot in Kreinitz (Germany) started in 2010 with 12 oak trees outplanted yearly between 2010 and 2019 over two 11m x 15m grassland plots. Soil temperature and soil moisture were measured between 2016 and 2025, and soil chemistry was assessed yearly in the root-affected zone of trees aged between one and five years. Soil porosity and texture were evaluated in 2020. The bundled publication is supplemented by recorded precipitation and weather data from an automatic weather station located on site.

INSPIRE Lebensräume und Biotope in Deutschland - Lebensraumtypen Wälder - Verbreitung

Der INSPIRE Dienst Lebensräume und Biotope in Deutschland - Lebensraumtypen Wälder - Verbreitung stellt bundesweite Verbreitungsdatensätze gemäß den Vorgaben der INSPIRE Richtline Annex III Thema bereit. Die Verbreitungsdaten wurden vom Bundesamt für Naturschutz aus Daten der Bundesländer und des Bundes zum Zweck der Erstellung des nationalen Berichts nach Art. 17 der FFH-Richtlinie zusammengeführt. Die Ursprungsdaten wurden von den Bundesländern nach den Anforderungen der EU für den nationalen FFH-Bericht nach Art. 17 der FFH-Richtlinie bereitgestellt. Die Informationen beziehen sich in der Regel auf den Zeitraum von 2000 bis 2012. Für einzelne Lebensraumtypen können abweichende Zeiträume berücksichtigt worden sein. Konkrete Informationen hierzu sind den sachlichen Berichtsdaten unter Ziffer 1.1.3 zu entnehmen (https://www.bfn.de/nationale-ffh-berichte).

Lichen plots of Fraxinus excelsior and Quercus robur at the Leipzig Canopy Crane Facility

Using the Leipzig Canopy Crane Facility situated in the temperate floodplain forest of Leipzig, epiphytic lichens on Fraxinus excelsior and Quercus robur were sampled between fall of 2016 until summer of 2017. A layered design was applied: Tree crowns were divided into five equally-spaced crown layers, with the trunk below the crown as an extra layer. In each layer a number of plots proportional to that layers bark surface area was placed. In each plot (100 cm²), lichen cover was documented. In addition, descriptors, such as branch diameter, height, position within the tree and LAI were measured. And supporting information on the identification the the lichen species. The goal was to determine epiphytic lichen diversity and distribution patterns and to infer mechanistic explanation of their emergence.
