Dutch Mammal Society (English pages)

The Dutch Mammal Society is an independent, non-governmental organization. We seek to bring together all those doing research on wild mammals and their habitats as well as those engaged in their conservation. Our work is carried out by volunteers and the staff of the office in Nijmegen.


The Dutch Mammal Society was founded in 1952 by a small group of scientists studying wild mammals. Today, our members are from many different backgrounds and their  numbers have grown to some two thousand. There is no barrier to membership, but members generally tend to be either professionals or volunteers with a professional level of expertise.

Research and conservation

The conservation work of the Dutch Mammal Society is based on research, the results being used for the protection of wild mammals and their habitats. Although most projects are in the Netherlands, we also work with other nature conservation organizations both at home and abroad. We are member of International Union for the Conservation of Nature (IUCN), Bat Life Europe, Eurobats and a partner of Natuurpunt in Belgium and the German Society for Mammalian Biology (DGS). As well as spreading our work in peer-reviewed articles, we share our expertise by giving courses and workshops,  and publishing brochures and books.
At present, the Dutch Mammal Society has fourteen volunteer groups carrying out inventories and monitoring. Monitoring may cover a broad range of species in a specific part of the country or concern a specific species, such as various species of bat, beaver, otter, pine marten or one of the  small mustelids.

Consulting office of the Dutch Mammal Society

The consulting office of the Dutch Mammal Society is located with a number of other nature conservation NGOs at the Natuurplaza in Nijmegen. Here a staff of seventeen is engaged in coordinating observer networks, assembling data on the occurrence and distribution of species as well as for trends. We are also developing standards for broad-scale fieldwork.

Another area of our work  is connected with the occurrence of a protected mammalian species on potential building sites, mainly in large infrastructural or rural development projects. We look into the risk of negative effects and how these can be mitigated.
