Field Study Group (ENG)

The Dutch Mammal Society is an organization dedicated to the study and protection of mammals. In this organization volunteers, both professional and amateur mammal experts, co-operate amicably. The Field Study Group, a sub-division of this organization, specializes in carrying out mammal surveys in the field. Every year the Field Study Group uses a variety of techniques to this end. It plays a key role in trying out new and innovative surveying methods.

During the year, the Field Study Group organizes several field activities in the Netherlands. A yearly summer camp abroad is also a traditional part of the programme, both aimed at surveying mammal species which are rare or absent in the Netherlands, and at extending and exchanging knowledge of the presence and abundance of mammals. Summer camps abroad invariably take place in co-operation with local wildlife organizations in order to fulfil the Mammal Society's aims as well as those of our foreign counterparts. Information gathered this way is more likely to play a role in the protection and management of the area in general and of mammals in particular.

Every year a report is compiled using the data gathered during the summer camp. Most reports are written in Dutch, but some of the more recent reports are available in English or have an English summary. All reports, some of them quite extensive, can be downloaded from this website. Simply click on the report listed below and the report will be opened in PDF-format. Please note it may take some time to open reports that are larger than 4 Mb. In such cases it is recommended to right-click on the title and choose the "save as" option. If you have any trouble opening or downloading a report, please inform the Field Study Group . A full publication list containing all the reports published by the Field Study Group (including those in Dutch) can be found at our publication page. A summary of the reports written in French you can find on the French report page.

Sightings databases

During the summer camps abroad the Field Study Group collects data on both mammals and non-mammals. All data is collected in a database. Conditions for use of these databases can be obtained from the Field Study Group.

A database with all data is available for the following locations:

All of the records in the databases can be accessed through the GBIF-portal as well (click here).
