ONCFS

Improving our understanding of how wild European hamster populations behave

Farmers in Alsace, supported by the CARA (Alsace Chamber of Agriculture), are currently testing innovative crop growing methods that should increase the European hamster’s chances of survival. In order to monitor these wild animals, the ONCFS (National Hunting and Wildlife Bureau) has conducted a campaign to identify hamsters on the plots of land in question.

The ONCFS and CARA join forces to improve European hamster habitat

43 females and 30 males were captured and marked over 16 nights on the experimental plots of LIFE project action C1. These experimental plots are located in Ernolsheim-sur-Bruche, Altorf and in the Obernai area.

Preparation of bait and laying the traps

Traps were placed near the entrances of monitored burrows and the hamsters were attracted by an inventive mix of onions, potatoes and peanut butter.

Sexing, measuring and chip checking

Once captured, individuals were weighed, measured and fitted with microchips. Fur samples were kept for future genetic analysis.

The females are marked so they can be monitored throughout their active phase (from April to October), allowing researchers to learn about their survival rate and the number of litters (and young) they raise. The resulting analyses can then be used to assess the impact of innovative farming practices on the hamster’s survival and reproduction parameters.

Telemetric tracking

The ONCFS will be responsible for telemetrically tracking these first adult wild hamsters throughout the summer until they hibernate.
