Data van: Gunstige abiotische bereiken voor vegetatietypes in Vlaanderen - Favourable abiotic ranges for vegetation types in Flanders

(English below)

Deze Zenodo deposit bevat data over de gunstige abiotische bereiken die gepubliceerd werd in Van Calster et al. (2020). Een gunstig abiotisch bereik is het globale meetbereik van een milieuvariabele waarbinnen een habitattype duurzaam kan functioneren op lokaal niveau.

Het bestand VanCalster_etal_2020_Gunstig_abiotisch_bereik_per_milieuvariabele_en_habitatsubtype_v01_00.txt bevat het cijfermateriaal uit het rapport (incl. eventuele fouten).

Velden

The table contains 950 rows and 19 columns. The first row is a column header containing the name of the variables. The following list provides a brief description of each variable:

• Habitatsubtype: habitat code of the Natura 2000 (sub)type

• Subtype: code/name of the vegetation variants. For the aquatic types, we refer to the Flemish water type as used for the Water Framework Directive.

• Milieucompartiment: (environmental compartment) soil, groundwater, inundation water (flooding with water from an external source), water column/surface water, air

• Variabele: (variable) name of the environmental variable. For a more detailed explanation of the laboratory methods:

  • for FlaVen 2020: see section "variables in theFlaVen database" below.
  • for other sources, please refer to the original publication.

• Afkorting: (abbreviation) abbreviation used for the environmental variable

  • for FlaVen 2020: see section "variables in theFlaVen database" below.
  • GHW: Gemiddelde Hoogwaterstand = mean highest water level

• Eenheid: (unit) unit used for the environmental variable

• Toestwijze-bepaling: (method) for aquatic types, the measurements are first summarised using a certain statistic such as percentile, mean, ... (same method as for the Water Framework Directive)

• Teken: (sign) type of range

  • OG-BG: lower limit-upper limit

  • 10-90 perc: 10-90 percentile values

  • min-max: minimum - maximum,

  • < - >: less than - greater than

• Abiotisch bereik: (abiotic range) measurement range of an environmental variable within which a habitat type can be maintained on a long-term basis:

  • Abiotisch bereik: abiotic range as text field

  • Waarde1-Waarde2: lower limit and upper limit as text field

  • WaardeNum1-WaardeNum2: lower limit and upper limit as numerical value (as far as the conversion is possible)

• N gunstig: (n favourable) number of plots with favourable conservation status used in the calculation of the abiotic range. The definition of favourable conservation status is based on Oosterlynck et al. (2020, version 3)

• Status: source and method of deriving the abiotic range:

  • Dp: ranges calculated using INBO data, prediction intervals, local conservation status (LSVI) known

  • Dt: ranges determined by the Titan method (Baker & King 2010), LSVI unknown

  • Dk: ranges calculated using INBO data, quantiles, too little data to calculate prediction intervals

  • Lg: ranges derived from literature (LSVI clearly indicated)

  • Lk: ranges inferred from literature (LSVI inferred, based on site characteristics)

• Referentie: (reference) references used to determine the abiotic range

• Opmerking (comment)

• Wijziging: (modification) has this record been modified since Van Calster et al. (2020) and how
