In general terms, 65 % of the Flemish flora is found along the coast. In recent inventories approximately 750 taxa were noted. Data show an increase in species numbers although it is unclear if this is due to the increased frequency of surveys. A qualitative shift however is quit clear. Floristic composition of the periods 'before '940' and 'after '972' only show a 60% resemblance. More than half of the recently emerged species are not indigenous to the area.The specific coastal flora is characterised by higher numbers of species adapted to salt, dry, calcareous and unshaded places. Dune preferentials are found in several ecotopes: salt marches and upper beach zones; mobile dunes; dry, calcareous grasslands and moss dunes; calcareous scrubs and dune slacks. Dry dune grassland is by far the most species rich with approximately 50 target-species. In most ecotopes this figure is 20 to 30. Moss dunes and mobile dunes are more species poor; approximately 10 'target species' are found. Woodland and decalcified grasslands contain significantly less target species than inland counterparts.In the strongly modified coastal landscape, flora changed drastically as well. The increase in woodland- and scrub-species is evident. In dry herbaceous vegetations there is a floristic shift towards a lesser degree of coastal specificity. Finally a strong decrease in groundwater-dependant species and salt marsh species took place.","AbstractOtherLang":"Vaatplanten vormen een belangrijke taxonomische groep omwille van de relatief hoge soortenrijkdom en het functioneel belang binnen het ecosysteem. Globaal wordt 65 % van de Vlaamse flora ook aan de kust gevonden, recent betreft het ca. 750 taxa. De gegevens wijzen op een verhoging van het soortenaantal maar gezien de sterk toegenomen inventarisatie-inspanning is deze trend niet met zekerheid aan te tonen. Wel duidelijk is de kwalitatieve verschuiving. De perioden 'voor 1940' en 'na 1972' vertonen slechts 60% gelijkenis wat betreft florasamenstelling. Ruim de helft van de recent opgedoken soorten behoort niet tot de inheemse flora.Kustspecificiteit komt binnen de flora tot uiting in een hoger aantal plantensoorten aangepast aan zilte, droge, kalk- en lichtrijke standplaatsen. Duinspecifieke of -preferentiële soorten vinden we in verschillende ecotooptypen: zilte slikken en schorren en op het hoogstrand; in dynamische duinen; in droge, kalkrijke mosduinen en graslanden; in kalkrijke struwelen en jonge duinvalleien. Droge duingraslanden vormen de soortenrijkste ecotoop en herbergen ca. 50 aandachtssoorten. Bij het merendeel van de ecotopen ligt dit aantal tussen 20 en 30. Mosduinen en stuivende duinen zijn van nature soortenarmer maar toch worden in elk een tiental aandachtssoorten gevonden. Bossen en graslanden op ontkalkte bodems zijn beduidend armer aan [aandachts]soorten dan de binnenlandse pendanten.In het sterk veranderde kustlandschap is ook de flora gewijzigd. De toename van bos- en struweelsoorten vormt de meest uitgesproken trend. In de droge kruidachtige vegetaties is vooral een verschuiving vast te stellen naar een minder kustspecifieke soortensamenstelling. Verder is een duidelijke achteruitgang vast te stellen van freatofyten en van schorrensoorten.","BibLvlCode":"AMS","StandardTitle":"Vaatplanten","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":65558,"PubliDate":2004,"Pagination":"46-83","XtraPublOfAnaID":null,"ISBN":"90-403-0205-7","Volume":"22","Issue":null,"BRefMon":65548,"BRefMonRR":"<b>Provoost, S.; Bonte, D.
