Description

Descriptive and experimental studies on the ground vegetation of coniferous forests in Bavaria indicated the following phenomena: a. In N-limited pine forests recent eutrophication effects occur. b. The structure of the moss layer in coniferous forests sensitively reacts to very acid throughfall water (pH < 3.2). c. Oxalis acetosella is a forest herb with a relatively high Ca-demand for optimum growth and is thusly sensitive to distinct acid-caused Ca-losses in the top soil, or inhibition of Ca-uptake. (orig.)

Abstract (German)

Deskriptive und experimentelle Studien an der Bodenvegetation bayerischer Nadelwaelder wiesen auf folgende Phaenomene hin: a. In N-limitierten Kiefernforsten treten rezente Eutrophierungswirkungen auf. b. Die Struktur der Moosschicht in Koniferenbestaenden reagiert empfindlich auf starke Aziditaet (pH < 3,2) des Kronentraufwassers. c. Oxalis acetosella ist eine Waldpflanze mit relativ hohem Ca-Bedarf fuer optimales Gedeihen; sie reagiert daher empfindlich auf staerkere depositionsbedingte Ca-Verluste aus dem Oberboden oder eine Hemmung der Ca-Aufnahme.
