Report: Macroalgae: Occurrences of Lower Saxony Wadden (1990-2004)»

Description

Eutrophication affects many coastal areas that high anthropogenic nutrient intake suffers, and causes significant changes in the local flora and fauna as well as oxygen deficiency in the sediment. Since 1989 an eye-catching Mass occurrences of macroalgae (chlorophyta) on the eulitoral areas of the Wadden Sea, the distribution and density of the algae cover low Saxon Wadden Areas by Flying (1990— 2004) and ascents (1989-1994) in the Summer months monitored. This report summarises: all studies carried out together with regard to methodological aspects, extension and covering, Species composition and biomass on the phenomenon of Mass development of green algae until 2004 by NLWKN eutrophication affects many coastal areas suffering from anthropogenic nutrient inputs resulting in severe changes of the native flora and fauna as well as oxygen depletion in the sediment. Since 1989, when a mass development of macroalgae occurred in the intertidal of the Wadden Sea, the distribution and density of macroalgae (Chlorophyta) in the intertidal Lower Saxonian Wadden Sea region has been monitored by Means of aerial surveys (1990-2004) and ground truth (1989-1994) during summer months. This report summarises all investigations which have been conducted by the NLWKN concerning methods, distribution and density, species inventory and biomass of the phenomenon mass development of green algae.
