Surveillance and research survey the health status of the Danish wildlife continuously. The surveillance consist of both active and passive (necropsy of dead game submitted to and active (sampled on purpose to establish the health status of the species in a region) surveillance. Information from both surveillance programmes are used for research.

The purpose of the passive surveillance is primarily to report disease outbreaks or increased mortality and provide a basis for identifying the first cases of disease in an area. The passive monitoring may provide the basis for identification of possible causes, including new/exotic diseases

The active surveillance is targeted for selected populations where detailed studies can clarify the health status and the presence of specific microorganisms or toxins. The purpose of active monitoring is to evaluate the extent and importance of disease problems in wildlife. Diseases do not always cause increased mortality, but may cause other problems eg. low reproduction of reduced welfare. Furthermore, these studies may be designed to evaluate the need for wildlife management or intervention.
