Het meetnet flora en vegetatie van de Provincie Noord-Brabant

In 1995 the Province Noord-Brabant has started monitoring plant species and vegetations with a set of well-described monitoring-routes. Each route comprises 5-96 sections of ± 50 m. long, in which every second year the occurrence and abundance of previously selected species is being assessed. This article gives the first results after three rounds of monitoring. Some species have evidently declined in this period, while others show an increase. The increase of some species is related to the lessening of the influence of salt water in the Delta area, while others have probably profited of the large quantities of rain in the last years.
