Water quality - Guidance standard for the surveying of macrophytes in lakes
This guidance standard defines a method for surveying aquatic macrophytes in lakes - primarily for the purpose of assessing ecological status, using these organisms as an element of biological quality. The information provided by this method includes the composition and abundance of the aquatic macrophyte flora.
For a complete assessment of ecological status, other elements of biological quality should also be assessed.
The general principle of the approach described in this European Standard may also form the basis for the monitoring and assessment of macrophytes in lakes, for example, for conservation purposes.
Wasserbeschaffenheit - Anleitung zur Erfassung von Makrophyten in Seen
Diese Anleitung legt ein Verfahren für die Erfassung aquatischer Makrophyten in Seen, hauptsächlich zur Bewertung des ökologischen Zustands als biologisches Qualitätselement fest. Die hier gegebenen Informationen schließen die Zusammensetzung und die Häufigkeit aquatischer Makrophytenflora ein.
Für eine vollständige Bewertung des ökologischen Zustands sollten auch andere biologische Qualitäts-elemente bewertet werden.
Das Prinzip des in dieser Europäischen Norm beschriebenen Verfahrens kann ebenfalls als Grundlage für die Untersuchung und Bewertung von Makrophyten in Seen für z. B. naturschutzfachliche Fragestellungen dienen.
Qualité de l'eau - Guide pour l'étude des macrophytes dans les lacs
La présente norme-guide définit une méthode pour étudier les macrophytes aquatiques dans les lacs - principalement dans le but d'en évaluer l'état écologique, en se servant de ces organismes comme élément de la qualité biologique. Les informations fournies par cette méthode sont, entre autres, la composition et l'abondance de la flore des macrophytes aquatiques.
Pour une évaluation complète de l'état écologique, il convient d'estimer également d'autres éléments de la qualité biologique.
Le principe général de l'approche décrite dans la présente Norme européenne peut également constituer la base de la surveillance et de l'évaluation des macrophytes dans les lacs, par exemple à des fins de conservation.

Not applicable 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 amphiphyte plant that can grow submerged in the water up to completely above the water, typically under fluctuating water level conditions 3.2 aquatic macrophytes larger plants of fresh water which are easily seen with the naked eye, including all aquatic vascular plants, bryophytes, stoneworts (Characeae) and macro-algal growths (see EN 14184)
NOTE For this method, this term is taken to include macrophytes growing in the water and in the wash zone, including hydrophytes, helophytes, amphiphytes, as well as supra-littoral species in the wash zone (such as Carex). 3.3 belt transect band of defined width oriented at right angles to the shoreline or bank, which starts at the water line including the wash and inundation zones starting at the highest seasonal waterline and in lakes extends to the lowermost limit of the aquatic macrophyte vegetation NOTE 1 The aquatic vegetation (species composition, abundance, cover) is analysed within this transect. The transect can be virtual or physically delineated. NOTE 2 The lowermost limit can change over years, either the belt transect is then extended to the lowermost limit that can be expected ever, or the lowermost limit or the belt transect is left variable through the years. 3.4 ecological status expression of the quality of the structure and functioning of aquatic ecosystems, expressed by comparing the prevailing conditions with reference conditions (see EN 14184) NOTE As classified in accordance with Annex V of the EC Water Framework Directive (2000/60/EC).

5 Equipment: the following equipment list is suggested. 5.1 Equipment common to all surveys 5.1.1 High resolution maps of survey area, preferably laminated. 5.1.2 Range of plastic bags and hard plastic containers, for retaining specimens or the temporary storage of macrophytes requiring laboratory identification. NOTE Mosquito netting or lace bags are easier to use than plastic bags in water. 5.1.3 Waterproof labels 5.1.4 Pencils or pens, with indelible ink. 5.1.5 Field data recording system, using either waterproof sheets, a small cassette recorder or water-resistant portable computer;
5.1.6 Floras, relevant field keys and identification guides, and iconographs (illustrations), appropriate to the habitats under consideration; 5.1.7 Records from any previous macrophyte surveys of the lakeunder survey 5.1.8 Personal protective clothing 5.1.9 First aid kit 5.1.10 Notebook, preferable with hard back and water repellent paper. NOTE A pre-prepared pro forma is helpful in the field. This can be a pro forma count sheet with a list of taxon names and space beside each on which the abundance estimates can be made, or a notebook organised in such a way that taxon identities and numbers can be clearly recorded, or a computer program with facilities for direct entry of data. It is recommendable that design of the recording sheets or programs takes into account the requiremen
