Infiltratie-kwel gradiënt in een gradiënt van grijswit > bruin > groen > geel > blauw. De blauwe zones zijn mogelijke kwelzones en de gele zones de overgangsgebieden. Alle groene-bruine en grijswitte zones zijn infiltratiegebieden op een groot schaalniveau (1 tot 20 km). De grondwatertoevoer is in de blauwe zones permanent aanwezig en relatief stabiel. Door de permanente natte omstandigheden is veenvorming mogelijk.

Watervogels - Wintering waterbirds in Flanders, Belgium is a sampling event dataset published by the Research Institute for Nature and Forest (INBO). It contains information on more than 94,000 sampling events (bird counts) with over 720,000 observations (and zero counts when there is no associated occurrence) for the period 1991-2016, covering 167 species in over 1,100 wetland sites. The aim of these bird counts is to gather information on the size, distribution and long term trends of wintering waterbird populations in Flanders. These data are also used to assess the importance of individual sites for waterbirds, using quantitative criteria. Furthermore, the waterbird counts contribute to international monitoring programs, such as the International Waterbird Census (coordinated by Wetlands International) and fulfil some of the objectives of the European Bird Directive, the Ramsar Convention, and the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA). Here the dataset is published as a standardized Darwin Core Archive and includes for each event: a stable eventID, date and location of observation, and a short description of the sampling protocol, effort and conditions (in the event core), supplemented with specific information for each occurrence: a stable occurrenceID, the scientific name and higher classification of the observed species, the number of recorded individuals, and a reference to the observer of the record (in the occurrence extension). Issues with the dataset can be reported at https://github.com/inbo/data-publication/issues The following information is not included in this dataset and available upon request: roost site counts, counts from historical (inactive) locations.

This dataset contains eDNA metabarcoding data of fish species detected in 30 locations in the Belgian Part of the North Sea (BPNS). The seawater samples were collected during two different field campaigns in September and November 2021. The fish species were identified using 12S eDNA metabarcoding. The dataset includes amplicon sequence variants and their associated metadata. Study extend: The construction of offshore wind farms may affect local soft-sediment fauna. Hence, an efficient monitoring technique is needed to monitor the potential effects on the marine ecosystem. Here, we assess whether eDNA metabarcoding is a suitable alternative to monitor fish and epibenthos biodiversity in these difficult to access marine habitats. Water sampling and trawl surveys were conducted in parallel in 12 coastal and 18 offshore sites, the latter located inside and outside two offshore wind farms in the Belgian part of the North Sea. project ID: Bioproject Accession - PRJNA1032405 (https://www.ncbi.nlm.nih.gov/bioproject/1032405) [This dataset was processed using the GBIF eDNA converter tool.]

Deze GIS-laag bevat alle historisch permanente graslanden (HPG) en alle permanente graslanden (in VEN) in Vlaanderen die beschermd zijn door de natuurwetgeving, ofwel door een verbod, ofwel door vergunningsplicht voor het wijzigen van deze graslanden (art. 7 en 8 van het BVR van 23/07/1998 voor de historisch permanente graslanden, artikel 25§3 ten 2e van het Natuurdecreet en artikel 6 van het maatregelenbesluit voor de permanente graslanden gelegen in VEN). Binnen de landbouwstreek de Polder werden de historisch permanente graslanden en hun beschermingsstatus bovendien vastgelegd door de Vlaamse Regering (VR) op 27/11/2015. Buiten de landbouwstreek de Polder heeft de VR de HPG niet juridisch verankerd op kaart, zodat het hier louter om een informatieve kaart gaat. Buiten de landbouwstreek de Polder werd de biologische waarderingskaart (BWK) conform het BVR van 23/07/1998 (Bijlage IV en V) gebruikt als basis voor de aanduiding van de graslanden, gecorrigeerd met de teeltplannen van de verzamelaanvraag landbouw voor de periode 2018-2022. De beschermingsstatus kan geraadpleegd worden in het veld “statuut”: - Verbod (rood): HPG waarvoor een verbod geldt voor het wijzigen van het grasland. Beschermd door de natuurwetgeving (HPG door artikel 7 BVR van 23/07/1998, permanente graslanden door het artikel 25 natuurdecreet en artikel 6 van het maatregelenbesluit): verboden te wijzigen, zowel mechanisch, chemisch als door afbranden, evenals verbod op wijzigen reliëf en verbod op doorzaaien - Vergunning (oranje): HPG waarvoor een vergunningsplicht geldt. Beschermd door de natuurwetgeving (artikel 8 BVR van 23/07/1998): natuurvergunningsplicht voor het wijzigen, zowel mechanisch, chemisch als door afbranden evenals voor het wijzigen van het reliëf en het doorzaaien. - EKBG (rode arcering met kruisjes): graslanden die enkel beschermd zijn volgens de landbouwregelgeving als ecologisch kwetsbaar blijvend grasland (EKBG): wijziging verboden zowel voor het mechanisch wijzigen als het wijzigen van het reliëf. Het veld “basis_statuut” geeft de juridische basis weer waarop de bescherming van de HPG en de permanente graslanden berust, en de liggingen in gewestplanbestemmingen en overdrukken (habitatrichtlijn, vogelrichtlijn, beschermd landschap, VEN). Het veld “beperkingen” geeft weer welke bewerkingen verboden of vergunningsplichtig zijn. ! Wegens een technisch probleem worden t.e.m. 16 mei de statuten 'verbod + EKBG' , 'vergunning + EKBG' en 'verbod (VEN) niet gevisualiseerd in Geopunt. Deze zijn wel beschikbaar via de achterliggende service en de achterliggende data.
