DIN EN 14184:2014-08EN 14184:2014 (E) 5 Introduction Macrophytes are an important component of aquatic ecosystems and can be used to
31、facilitate the monitoring of ecological status. The requirement to use macrophytes in monitoring is inherent in numerous European directives (e. g. the Water Framework Directive (2000/60/EC), Urban Waste Water Treatment Directive (91/271/EEC), Nitrates Directive (91/676/EEC), etc.). In addition to t
32、heir important ecological role, the use of macrophytes as indicators of ecological quality in running waters is based on the fact that certain species and species groups are indicators for specific running water types and are adversely affected by anthropogenic impact. In certain types of running wa
33、ter habitats the lack of macrophytes is not an effect of anthropogenic impact but a characteristic feature. For example, in geological formations like the flysch, or in the central part of deeper rivers macrophytes may be absent due to the habitat limitations imposed by geology and substrate, water
34、depth, current flow velocity, turbidity, etc. A wide range of sampling and survey methodologies has been developed for specific applications including conservation, drainage impact, management, ecological habitat enhancement etc. The methodology of this guidance standard is recommended specifically
35、for the surveying of macrophytes in running freshwaters, of natural, heavily modified and artificial character, and for the purpose of monitoring ecological status. It could be used as the basis for investigative monitoring of water quality or other applications, as well. According to the precise us
36、age to which this European Standard is to be put, it is essential for specifiers and users to mutually agree on any necessary variations or optional procedural details prior to use. WARNING Working in or around water is inherently dangerous. Persons using this European Standard should be familiar wi
37、th usual field and laboratory practice. This European Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory cond
38、itions. DIN EN 14184:2014-08EN 14184:2014 (E) 6 1 Scope This European Standard specifies a method for surveying aquatic macrophytes in running waters for the purpose of assessing ecological status, using these organisms as elements of biological quality. The information provided by this method inclu
39、des the composition and abundance of the aquatic macrophyte flora. This European Standard is applicable to all kinds of surface running water bodies, like natural brooks, streams and rivers and their heavily modified equivalents, as well as to artificial water bodies like canals or run-of-river rese
40、rvoirs. The general principles of the approach described in this European Standard may also be applied when monitoring water bodies in the fluvial corridor of a river, such as side channels and oxbows. It is recognized that for a complete assessment of ecological status, other elements of biological
41、 quality should also be assessed. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 aquatic macrophytes larger plants of fresh water which are easily seen with the naked eye, or which usually form colonies, including all aquatic vascular plants
42、, bryophytes, stoneworts (Characeae) and macro-algal growths 2.2 bank permanent side of a river or island, which is above the normal water level and only submerged during periods of high river flow Note 1 to entry: In the context of this standard, bank species include macrophytes that overhang the c
43、hannel or overgrow the water surface but are rooted in the bank. 2.3 channel course of a river or stream Note 1 to entry: In the context of this standard, this includes only the in-stream part, i. e. that which is under water most of the time although it may be exposed temporarily under conditions o
44、f dry-weather flow or for longer periods under certain natural (climatic, geological) conditions. 2.4 belt transect defined band across a river or stream at right angles to the bank Note 1 to entry: This may be virtual or physically delineated within which the aquatic vegetation is analysed (species
45、 composition, abundance, cover). 2.5 ecological status expression of the quality of the structure and functioning of aquatic ecosystems, expressed by comparing the prevailing conditions with reference conditions Note 1 to entry: As classified in accordance with Annex V of the EC Water Framework Dire
46、ctive (2000/60/EC). DIN EN 14184:2014-08EN 14184:2014 (E) 7 2.6 helophyte plant usually rooted under water or in the wet part of the bank with emergent shoots, typically growing in marginal or marshy areas 2.7 hydrophyte aquatic plant that is usually rooted under water with floating or submerged lea
