Biological quality of lakes

REMOVE [1]

This indicator represents the Cyanobacteria percentage of total phytoplankton biomass. This is an indicator of eutrophication.

Data host: 

European Environment Agency

Unit of Measurement: 

Percentage (%)

Link to Data: 

http://www.eea.europa.eu/data-and-maps/indicators/biological-quality-of-lakes [2]

Description to get data: 

Goto http://www.eea.europa.eu/data-and-maps/indicators/biological-quality-of-lakes find Figure, the figure contains the data for this indicator. There is also an Indicator Fact Sheet in the section "Download detailed information and factsheets".

Type of Indicator source: 

  • Intergovernmental Organisation [3]

Geographical Coverage: 

Denmark
France

  • National [4]

Same/similar indicators appears in the following sets: 

  • EEA's environmental indicators/Environmental Pressure indicators [5]

Methodological transparency: 

  • Methodology not available [6]

Temporal Coverage: 

1985 to 2001

Frequency of Updates: 

  • irregular [7]

Indicator developer: 

European Environment Agency

Aggregation level of indicator: 

  • Aggregate [8]

Data quality assesment: 

  • No published quality assessment [9]

Publishing delay: 

  • more than 3 years [10]

Contribution to the green economy: 

A higher level of cyanobacteria as a percentage of total phytoplankton biomass indicates a higher level of eutrofication and therefore is worse for the environment and for the Green Economy in general.

Cost of accessing data: 

  • free of charge [11]
Potential misinterpretation: 
Is the amount of cyanobacteria declining, but the overall freshwater biodiversity and quality is declining/not improving?
Related Indicator: 
Freshwater biodiversity and water quality [12]
Potential misinterpretation: 
Agriculture is seen as main emitter of nitrogen. Are the critical loads of nitrogen declining because there is less agriculture?
Related Indicator: 
Agriculture, value added (% of GDP) [13]
