NDFF Endangered plant species project

The Endangered Species Project provides detailed accounts of a limited number of rare species that occur in the Netherlands. Old data about sites where species have been found are used to update the current state of these species through inquiry and field visits over a period of 1 or 2 years. Where does the species occur? What is its population size? What threats does it face? Apart from these selection plots, other square kilometre plots are also examined, preferably in areas for which there is no inventory data. Dataset available via https://www.ndff.nl/english / [e-mail] Positive observations without zeros. 3,963 records (March 2018) https://www.ndff.nl/overdendff/validatie/protocollen/12-002-bedreigde-soorten-project-floron/
