Topic Centre activities

Advisory services and other public-sector consultancy are provided primarily to the Danish Ministry of the Environment, but we also advise other authorities such as municipalities and private companies. As a part of the Water Framework Directive we develop indicators describing the ecological status of Danish streams and test whether indicators and status classes correspond with those that are used in other EU countries.

We work with indicators for phytobenthos, macrophytes, macroinvertebrates and fish. In connection with the Danish national stream monitoring programme (NOVANA), we develop monitoring methods and technical guidelines for those undertaking the monitoring, just as we intercalibrate the performance of the processes and procedures of the individual monitoring activities. The many results from the NOVANA are processed, analysed and published as an annual (DCE Scientific report).

We also advise on the organic effects of activities such as stream maintenance, water abstraction, emission of environmentally hazardous substances and much more. All our advisory activities are based on research and other knowledge-building. A large part of the advisory activities is undertaken as part of a framework agreement between Aarhus University and the Ministry of the Environment; other tasks are solved on the basis of separate agreements.

Ongoing projects within this topic

Technical guidelines

Technical guidelines for the many different types of studies carried out as part of the NOVANA monitoring. The guidelines span methods for monitoring communities of phytobenthos, macroinvertebrates, fish and macrophytes, monitoring of individual species such as thick-shelled river mussel, freshwater pearl mussel, lampreys, twait and allis shad as well as spined loach, to descriptions of physical conditions, environmentally hazardous substances and heavy metals. The project is financed by the Danish Environmental Protection Agency (framework agreement).

Intercalibration

Intercalibration of the methods used in accordance with the technical guidelines. Thematic examples: Sampling of invertebrates in streams (TA V07), investigations of macrophytes in deep streams (TA V17), physical index study (TA V05). The project is financed by the Danish Environmental Protection Agency (framework agreement).

Reporting of NOVANA data from streams

Reporting of NOVANA data from streams is undertaken annually. The report describes the status and development of the physical, chemical and biological status of the streams. Focus chapters deal with special topics that vary from report to report. The project is financed by the Danish Environmental Protection Agency (framework agreement).

Article 17 reporting on species/nature types associated with streams (and lakes).

The EU Habitats Directive obliges the Member States to report the status of a number of species and habitat types every 6 years. Three habitat types and 12-13 species are specifically linked with streams. The project is financed by the Danish Environmental Protection Agency (framework agreement).
