Introduction
Investigation of marine angiosperms (e.g. seagrasses) and macroalgae is an important part of marine
environmental monitoring, facilitating the assessment of general ecological quality and the monitoring
of ecological status. The requirement for using marine angiosperms and macroalgae in marine
monitoring is inherent in numerous European and national directives: e.g. Marine Strategy Framework
Directive (Directive 2008/56/EC), Water Framework Directive (WFD) (Directive 2000/60/EC), Urban
Waste Water Treatment Directive (91/271/EEC), Habitats Directive (92/43/EEC) and the OSPAR and
HELCOM conventions. Extensive green macroalgal beds are considered an indicator of eutrophication.
Seagrasses and some macroalgae species are important contributors to biodiversity, as well as IUCN
threatened species and they are investigated in very similar ways. They respond to environmental
changes - primarily availability of light, nutrients, temperature and are impacted by physical
disturbance. Monitoring of extent of area, biomass and species composition may therefore in many
cases be used to characterize the environment and the degree of impacts.
The characterization of environmental conditions based on marine angiosperms and macroalgae
requires the use of quantitative and qualitative mapping methods.
