Overview of biodiversity of the Netherlands

The Dutch Species Register provides a current and comprehensive overview of Dutch biodiversity. It is based on the data gathered by experts in various aspects of flora and fauna. Dutch biodiversity is among the best investigated in the world. This research has resulted in numerous papers, reports and books. The Dutch Species Register combines this information for the first time in history, and, in this way, it contributes to international biodiversity networks as Fauna Europaea and GBIF.


The Dutch Species Register offers:

- A reliable list of the species recorded in the Netherlands
- A comprehensive taxonomic tree of the species
- Standardized ecological status of the species in the Netherlands
- Sources and consulted specialists per taxon
- Numbers of  species/names per taxonomic level
- Continuous addition and improvement of the species data by Dutch specialists 

Target groups

The Dutch Species Register aims to inform policymakers, biodiversity researchers, consultancy firms, journalists, nature wardens and the interested layman and offers an answer to the following questions:

What is the correct name of the species?
Starting from the scientific name (with author information). Dutch name, synonyms and former names are also given.

What is the status of the species in the Netherlands? 
A distinction is made between species that naturally occur and introduced (alien) species.

Where does the species fit in the taxonomic tree?
The generally  accepted current taxonomic classification is offered.

What does the species look like?
Photographs of species are added continuously.

Where does a species occur?
The addition of distribution maps has been started.


A large number of scientific institutions, individual experts and organisations of volunteer recorders contribute to the Dutch Species Register, e.g., the National Herbarium, Fungal Biodiversity Center, Naturalis Biodiversity Center, Zoological Museum Amsterdam, European Invertebrate Survey - the Netherlands (EIS) and the Dutch Ministry of Economic Affairs, Agriculture and Innovation (the ministry provides information on the legal and policy status of the species). Dozens of individual specialist are contributing as well. They often participate in one of the nongovernmental organizations that contribute to biodiversity data collecting.

Naturalis Biodiversity Center and EIS organise and coordinate the Dutch Species Register, that has been supported financially by the Dutch Ministry of Economic Affairs and NLBIF.

The Dutch Species Register serves as a national node of the Encyclopedia of Life (EOL).
