Their former and present distribution in the Flemish coastal dunes is reviewed. Of the 11 taxa ever recorded in the area, only 7 were observed after 1997. These represent 25% of the Flemish charophyte flora. Presently, <i>Chara contraria, C. Major</i> and <i>C. Vulcaris var. Loncibracteata</i> are the most frequently occurring charophytes. <i>Chara aspera, C. Baltica</i> and <i>Nitella translucens</i> disappeared long ago, and it seems unlikely that they will reappear. Along the Belgian coast, charophytes are best represented in the Westhoek reserve and surrounding dune fragments. The coastal dune area is of considerable importance for the survival of <i>Chara major</i> in Flanders. Establishment of charophytes is strongly linked to pioneer conditions, which should be accounted for in management practice. In general, care should be taken to preserve a sufficient part of the oospore bank during pond maintenance. Also, every possible cause of eutrophication, for instance by large grazers, should be avoided.","AbstractOtherLang":"Kranswieren [Charophyceae] zijn belangrijke doelsoorten voor duinwateren. Een overzicht wordt gegeven van het voormalige en actuele voorkomen van deze groep in de vlaamse kustduinen. Van de 11 ooit in het gebied aanwezige taxa zijn er 7 nog na 1997 waargenomen. Deze vertegenwoordigen 25% van de vlaamse kranswierenflora. <i>Chara contraria</i>, <i>C. Major</I> en <I>C. Vulgaris var. Longibracteata</i> zijn heden de meest frequent optredende taxa. <i>Chara aspera, C. Baltica</i> en <i>Nitella translucens</i> zijn reeds geruime tijd verdwenen en hun herverschijning is zeer onwaarschijnlijk. Het duingebied is van bijzonder belang voor het voortbestaan van <i>Chara major</i> in Vlaanderen. De westhoek en de hier nabij gelegen duincomplexen vormen voor kranswieren het voornaamste deelgebied. De uitbreiding van kranswieren in de duinen is sterk aan pioniersomstandigheden gekoppeld, zodat een kranswiergericht beheer hierop dient te steunen. Bij het schonen van plassen met kranswiervegetaties dient de oösporenbank best in voldoende mate gevrijwaard te blijven. Tevens moet elke vorm van eutrofiëring, bijvoorbeeld door grote grazers, worden vermeden.","BibLvlCode":"AMS","StandardTitle":"Kranswieren","OrigTitleLangCode":"nl","OrigTitleLangCodeExtended":"dut","OrigTitleLangID":41,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2012-09-11","DateCreate":"2004-08-31","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":65578,"PubliDate":2004,"Pagination":"106-121","XtraPublOfAnaID":null,"ISBN":"90-403-0205-7","Volume":"22","Issue":null,"BRefMon":65548,"BRefMonRR":"<b>Provoost, S.; Bonte, D.
