Therefore, the sampling area of the second National Forest Soil Inventory (NFSI) with the BIOSOIL grid was used to investigate the contents, stocks, and spatial distribution of persistent organic substances in forest soils. The investigated substances were polycyclic aromatic hydrocarbons (P

Plants as Indicators of Soil Chemical Properties,on is based on the data of the second National Forest Soil Inventory (NFSI II) in Germany. Generalized linear models were used to calibrate species response curves for soil parameters that significantly affect vegetation. These response curves are used to indicate the most probable value of the soil

Spatial Response Patterns in Biotic Reactions of Forest Trees and Their Associations with Environmechanges in forest soils and with other environmental variables were investigated. The study aimed to identify areas at risk and risk factors. Growth ring widths and defoliation indicated drought stress as main risk factor. High annual mean temperature deviations of approximately 1.5 °C from the long

Sustainable Use and Development of Forests and Forest Soils: A Resume,ns for forestry and forest policies. Clean air policies and forest liming show an effect against soil acidification with sulfur and total acid deposition strongly decreasing over the last decades. Forest liming proved to be suitable to preserve acid-sensitive forest soils. Nitrogen eutrophication re

An Exploratory Case Study on Student Teachers’ Experiences of Using the AR App Seek by iNaturalist Wds, semi-structured interviews were conducted with three student teachers. A thematic analysis approach was used to explore the student teachers’ experiences when using Seek. The findings indicate that Seek increases student teachers’ awareness of plants, which promotes their interest and engagement
