NDFF Wall Plants Monitoring Program

Latest version published by Dutch National Database of Flora and Fauna (NDFF) on Oct 19, 2021 Dutch National Database of Flora and Fauna (NDFF)

The aim of the Wall Plants Monitoring Program is to facilitate the structured counting of wall plants. First, a selection is made of line transacts with a maximum length of 300 metres. Then, growth locations of wall plants within those transacts are mapped as points on a map or indicated by house numbers. The number of specimens is counted at each point.

The protocol contains a list of the species that need to be measured. Depending on the age of the wall, an indicative visit duration is given. Since there are only a few species of wall plants, it is not necessary to have comprehensive knowledge of Dutch flora. Specific identification problems are not addressed in this protocol.

Dataset published to GBIF in 5x5 km detail as a pilot datapublication. Detailed dataset available via https://www.ndff.nl/english / serviceteamndff@natuurloket.nl
