FLORIVON

Study Extent

The survey consisted of single visits of a half to one day in map squares of approximately 1,3 x 1 km until most of the country had been sampled.

Sampling

During single visits of a half to one day all vascular plants were registered on a species list.

Quality Control

Older nomenclature has been converted into newer nomenclature (Heukels’ flora 2005). Observations were checked against the plant atlas (Atlas Nederlandse Flora) with a coarser grid. Observations that would lead to a new 5 x 5 km grid cells are temporarily omitted. To do when digitizing is finished: * check records that could not be validated (not yet published in GBIF) * split lumped taxa (if possible) * final check of selected taxa by experts

Method steps

1. * data entry in Turboveg with adapted taxon list (names en numbers cf. Prodromus Florae Batavae) * conversion of taxon names to currently accepted names. We use ‘taxon combinations’ if lumped taxa were recorded * data validation against generalized distribution maps of the Atlas Nederlandse Flora, which is an edited abstraction of the current dataset * conversion of IVON grid system shapefile to WGS84 WKT strings * conversion to MySQL database for publication in IPT * estimated total project costs / time: 120 k€ / 5 years (to be finished in 2018)
