The Flora of the Brussels Capital Region has been intensively surveyed during the period 2003 to 2005. The whole area of its 19 municipalities, 162.4 km², was divided according to a grid of 1km² sqaures. In each of these 195 grid squares the presence of all vascular plants species was noted during the spring and summer.

More than one million people inhabit Brussels, so the density of its population reaches some 6200 inhabitants per km². Nevertheless, 793 different taxa have been observed within the region. In 96.4% of the grid squares at least 90 species occur, but on average the number of species per square was 204. Seven squares contained more than 300 taxa and the maximum number was 320.

The surveying was performed by Dr Luc Allemeersch of the NBG (National Botanic Garden of Belgium) by order of the BIM/IBGE (Brussels Instituut voor Milieubeheer/Institut Bruxellois pour la Gestion de l’Environnement). The data for the maps was digitised at the INBO (Instituut voor Natuur- en Bosonderzoek).

On this website the distribution maps of 791 different taxa can be consulted on a changable background map, showing woodland, roads, wastelands and wetlands. For each of the species the scientific name is given, as well as its vernacular names in Dutch, French, English and German and a concise comment on the main characteristics of its distribution in the Brussels Capital Region.

Some more technical information on the mapping project is under construction.
