Genetic screening of Reeves' muntjac continued
Reeves' muntjac is a small exotic deer that was introduced to Europe from China. In Great Britain, the muntjac is now very common and causes a great deal of damage to forests. To prevent a similar spread on the mainland, the muntjac is therefore on the European list of invasive species of concern. In Flanders, the animal has been regularly observed since 2013, more than anywhere else in the European Union.
In 2022, INBO conducted an initial genetic study into the relationships between animals from Flanders. This involved both captive and wild muntjacs. By detecting variations in the genome and comparing them between individuals, we were able to deduce related groups and even family relationships.
In a follow-up study, we analysed 74 new or previously unprocessed samples from Flanders and surrounding regions. The genetic database now contains data from 212 animals. The results confirm patterns of distribution through natural dispersion and human activity. Certain clusters extend across several, often neighbouring municipalities, and even across national borders: for example, an animal from the Netherlands appears to have originated from a population in Antwerp.
The genetic database provides valuable information about the distribution of muntjac and is an important tool for monitoring and enforcement.
