# EUNIS littoral biogenic habitat types (salt marshes) probability maps - version 1, Nov. 2021

This metadata describes the EUNIS littoral biogenic habitat types (salt marshes) distribution datasets created from habitat probability mapping. Probability maps are refined versions of habitat suitability maps. Suitability maps model areas where the environment is suitable for a certain habitat type. Probability maps include information on existing land cover and narrow the modelled suitable distribution to areas where the habitat type is probable to occur.

Littoral biogenic habitats (commonly known as salt marshes) are formed by animals such as worms and mussels or plants.

The verified saltmarsh habitat samples used are derived from the Braun-Blanquet database (http://www.sci.muni.cz/botany/vegsci/braun_blanquet.php?lang=en) which is a centralised database of vegetation plots and comprises copies of national and regional databases using a unified taxonomic reference database. The geographic extent of the distribution data are all European countries except Armenia and Azerbaijan.https://sdi.eea.europa.eu/geonetwork/srv/api/records/7a2d78ec-8a31-4e7b-91df-45db6e64e842
