Methodology

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 description

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 news (Heukels' flora 2005 nomenclature). 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.

Method Steps

  1. * data entry is Turboveg with adapted species list and nomenclature * conversion of gridsystem to coordinates (Arcview, Access) * conversion of old plant names to recent ones, including 'sensu lato taxa' if lumped taxa were recorded at that time * data validation against a coarser grid map in Access * conversion to MySQL database for publication in IPT
