Observations of vascular plants by botanists from the period 1901-1949. Data have been collected in 1.3 x 1 km grid squares. The entire country of the Netherlands was surveyed. Since records are currently being digitized, the FLORIVON dataset is still growing. We estimate the final number of records on 1,400,000. We digitize ~200,000 records per year and finish the digitizing project in 2018.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 1,368,448 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Sampling Methods

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

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.
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 step description:

  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)

Collection Data

Collection Name FLORIVON map archive

Additional Metadata

Purpose The data was collected for the publication of the Atlas Nederlandse Flora (published between 1980 and 1989). Data will now be used to complement the flora datasets maintained by FLORON in the National Database Flora and Fauna.
Maintenance Description We will add new data annually until the digitazation has been completed (2018).
